First day of this transmission it would appear.
Some quick observations: the SDC text was incorrect, reading "9800 kHz 20:45-23:59 UTC **From Sackville NB, Canada for your listening pleasure,
to North-East USA.** All FAC data was correct. Second, the Parametric stereo was not balanced well, with the right channel rather loud compared to the left channel. I checked my PC settings and they were set correctly, so somewhere the source balance is off. Resetting my balance by about 80/20% Left to Right fixed the sound. Lastly, there was several minutes of dead air at first, no audio was heard.
Nice strong signal. No close interference observed, only very weak analog signals on 9800 and 9780. The observed maximum audio bandwidth was about 13.5 kHz. Several dropouts heard, but only shown on the SNR to Correctly Decoded Frames History. No interference seen on the waveform (like lightning or electrical) I'm not sure what was causing this to happen, nor is the SNR taking any hits. Big SNR hit at 0042Z: looked like some strong, local interference caused that.
Dream crashed at 0044Z; restarted and continued logging. So this log will be in two parts. The second part is showing the wrong frequency: Dream didn't reset when I restarted the log.
0052Z: SDC now says "ww.tdpradio.co. Enjoy"
Tomorrow: I will run DRMSWR as it is more reliable.
This evening's transmission started very strong S9 +40dB plus, and then something happened and the signal dropped 40db. Was it a solar flare (CME)? :confused:

I must have started to post at the same time Brendan did. :)

Hi Zyg,
seems Brendan was first ;)

Btw nothing could be received on this transmission here in Germany.

No log: something went wrong and I have no data to show, so a written observation follows.
Music started right on time, stereo balance issue has been fixed. Logging other DRM broadcasts today has shown ionospheric conditions to be down from yesterday: so far this one looks good. SDC still showing CBC's message with wrong frequency and time.
A second, analog receiver shows 9790 coming at S9+20dB here.
Starting at about 0029Z, a series of very short audio interruptions began. They sound like source problems, not transmitter faults. Signal data doesn't show any drops or interference. Stopped by 0042Z.
SNR was at least 16 to 18 db the entire broadcast. Generally the signal was quite steady, although slightly down in SNR from yesterday.
Same as last night.
The MUF changes just after the start of the transmission. :(
A screen shot of the Dream desk top at the 15 minute (approx) point of the transmission.
Note that the ID screen still shows 9800 kHz 20:45 - 23:59 UTC...

Just to gripe a bit, but...what the hell! Why wasn't this sked sent out to the North American crowd? Not in DReaM skeds either.
I'm copying now and although the band is not that good, I have some audio. The P-Stereo is screwed up (almost no Left channel at all).
I'll post a log later.
Anyway, I stumbled on the broadcast. Will listen more regularly to see if it remains. Just one more incident of the broadcasters not being on the ball or even communicating with the North American monitors! It is sad, but I fear DRM is doomed over here due to the huge delays and lack of communication, oh yeah NO DAMN DRM RADIOS EITHER :mad:
Based on my frustration, I have started a Yahoo group for DRM in North America:
DRM North America Yahoo Group
http://groups.yahoo.com/group/drmna/
A group for discussion of Digital Radio Mondiale (DRM) broadcasting in North America. Members may be from anywhere around the globe, but discussion should revolve around programming and reception issues of those living in Canada, USA and Mexico.
Join if you like. This group will NOT be for reception reports, more for coordinating efforts.
I think I'll go have another beer and chill to the Trance...

Chris - this was only just scheduled back on Tuesday. It came up on the schedules when I was updating for the 17810 TDF/RNW broadcast. I found it then, and jumped on it that same day. Not sure why no one "broadcast" it to the NA DRM crowd.
Here are todays' notes:
Nice SNR, came up fast. SDC and FAC both showing CBC info, and wrong info at that. No audio for first 4 minutes, then RCI interval signal popped up. I/s ran for 2 1/2 minutes, then no audio again.
0015:49Z - finally, audio! 0017:53Z: stereo popped up, FAC now shows TDP radio and mono, but balance definitely changed to about 95% right channel, 5% left. FAC completely corrected by 0019:56Z. SDC still wrong for entire broadcast.
The first 16-17 minutes were really high quality digital silence, with a few minutes of the RCI identification loop in English and French.
Just when the audio finally started the conditions changed just as they have in the last couple of days.
Chris (Fibber): a friend of mine received notification from RCI about the new transmissions - but that was because he sent a reception report directly to them. I agree, RCI could have sent out a more general announcement.
The ID screen still showed 9800 kHz - so it looks like RCI doesn't monitor the output.
Brendan,
Thanks for your words and efforts. Here is my first log of this broadcast. Freq shows incorrectly, my fault. I was using HRD and SDRadio so when I saw the DRM waveform, I switched to DReaM and didn't have rig control going. I manually tuned.
CRI English came up on freq after with good signal but not so good audio. Makes me wonder about CBC. Oh well.
Dear friends in NA,
We do understand the concerns regarding not publicizing more about the TDPradio broadcasts.
As we did not wanted to be promoting something through the forum, we did send a press release to the moderator on Monday evening and a thread was starting from day 1 by the moderator.
If you want to read the press release, then go to the news page at www.tdpradio.com for the full content.
We do want to bring some new original content for DRM to NA and hope that our initiative is appreciated and followed by many others.
Kind regards,
Ludo

Ludo -
Thank you for getting back to us. Having an evening/late afternoon broadcast is a nice change. Most DRM broadcasts for North America are usually during the workday for many of us. I've been able to do a lot of logging while I've been unemployed, but no more: my new job starts today. Any logging I do will be automated, and filed much later when I return home.
By the way, you should seek a refund for nearly 16 minutes of broadast time for todays' broadcast at 0000 UTC: there was no audio from CBC Sackville at all! As Zyg/AF4MP said, it was "really high quality digital silence."
Have to go, thanks again.
Ludo,
Us North Americans LOVE another choice on DRM! Thank you! As far as
"not wanted to be promoting something through the forum"... We use DRMRX as our lifeline to what is going on. Unless you have been told NOT to promote broadcasts, we'd really appreciate hearing about tests, broadcasts, etc.
Regarding audio and other things: CBC often goofs with mono or one channel stereo, no audio, wrong text, etc. Perhaps you just have to keep reminding them about what you want and expect.
Regards and don't take my complaints (previous posts) too seriously!

This was the first day this week that I got home from work early enough to try for this transmission. Analog RCI on 9755 wasn't much better. Then I checked the solar indices and found that the A index was 21! Better luck next week, I hope.
Brendan1
14-10-2006, 02:03
Well, well, well. Sackville is on the ball today. Music started right away, both
the FAC and SDC are correct for TDP.
Only one little criticism: the audio is still coming across as about a 98% right
channel, 2% left channel mix. VERY lopsided. One thing I've noticed about the
parametric stereo mode is that it seems very susceptible to what appear to be minor fluctuations in SNR. Only a few tenths of a dB down, and the audio does a quick fadeout, fadein. I would not be surprised if this isn't normal because of the added complexity of two distinct channels being subjected to signal fading. It is as if one channel gets out of phase and starts cancelling the channel that isn't out of phase.
Zyg's disease hit me today: starting at around 0035Z, so many hits to the signal started coming that almost no audio was decoded. SNR has also deteriorated badly as well. I tried to copy Vatican Radio just before this (9750) and had nearly no signal at all. Propagation is definitely off, and Allan's comment is spot on.
Ludo, please convince CBC to transmit at something other than 20.88 kbps. Audio fidelity may suffer slightly, but the signal will travel farther. We North Americans have a lot of experience with signals that almost make it, but never decode well because of the transmission speed :(
Propagation was down the crapper today! CBC was awful, no Vatican or Kuwait.
The early Montinsery RNW test was the only good DRM all day. RNZI right now is even missing!
Ditto on Brendan's post. It seems that a 17.8 or so bitrate in Mono might make for more stable listening. I realize Ludo is into Stereo DRM, which is fine if there is enough signal and SNR.
I'm in a poor spot in the Pacific North West to be copying Sackville anyway. The new French Guyana transmissions really show some promise however. Several days of nearly 100% audio over the whole on-air time!
Brendan1
15-10-2006, 02:02
Hmmmm, somebody must have shaken CBC's tree. Two days in a row they start TDP's broadcast on time, with all the right info. Still having audio problems: overwhelmingly lopsided on the right channel again. Can somebody pleeeease fix it?
Just a few very short audio dropouts at the beginning. Propagation seems to be less disturbed today, although the sunspot number is lower.
Some more dropouts from 0035 to 0050Z; SNR fluctuating downward then back up.
Overall, much better than yesterday's broadcast. CBC shut down a minute early though!
This evening's 9790 kHz reception report.
The path between Sackville and Atlanta stayed open 30 mins. longer tonight! :)
The drop in SNR in the first 15 minutes was my fault - an intermittent fault in the cable between the radio and computer.
As Brendan said, most of the audio was in the right channel. I wonder if anybody at the transmitter site actually monitors the audio output?
-Zyg-
Brendan1
16-10-2006, 02:02
Excellent reception today. Only a couple of short dropouts, otherwise good quality signal. The previously mentioned audio problem is still with us however. Too much right channel... :( Propagation was much better today.
Alan Johnson
16-10-2006, 02:03
Wow! The left channel is still way down in amplitude, but what a signal. The major dropouts were due to me clicking on the second service tab, which showed "GDW" with audio and text, but no audio was present.
Brendan1
17-10-2006, 02:05
ALRIGHT! The audio is fixed! Good well-balanced stereo today. The SDC was showing just the usual Sackville message about transmitting for your listening pleasure to the NE USA, no TDP text. The FAC was all TDP and correct.
Good report all told. Just a few, quick dropouts.
This evening's 9790 kHz reception report. SNR too low for audio at the beginning of the period, then improved, and then finally settled on the border between audio and no audio.
Interestingly the S-meter signal strength was high, between S9+20dB and S9+30dB. Signal delay seems to be the culprit (I have also attached the Dream desk top screen shot taken at about the 57 minute point in the broadcast).
When the audio was on it sounded great, and with good stereo separation.
-Zyg-
This evening's 9790 kHz reception report.
No audio was decoded tonight. :mad:
The signal strength on the S-meter was only S9 (varying +/- 5dB) throughout the transmission period.

DRMLogger is not recording when I want it too. :( Had to hand start this log, and so only got the last few minutes of the broadcast.
Came through well, no problems heard for those few minutes.
Brendan1
19-10-2006, 02:09
Not very good today. Many dropouts, and the graphed data shows it.
Brendan1
20-10-2006, 02:04
A great start, then a lot of dropouts as the log shows. I suspect the low sunspot numbers are at work here. But, the graph starts declining just at the time local sunset occurs, so the shifting layers may also be at work.
I ran my CCrane modulator and listened to TDP on FM while I made dinner (via my DE1103). Great sounding when it was in! I plugged a pair of headphones in to hear the stereo. Sounded balanced! Signal kept getting worse until NADA!
Hi,
Just for fun I let Windows start up Dream from its sleep just after midnight UTC. It was not much to "see", from the back lobe, but on the other hand I was asleep and cannot confirm what was on the channel at that time of night. Seems to have been some bursts of music. Did anyone notice the Audio Level in the "Sound Spectrum" window? Is it as loud as on 6.015 MHz?
Terje
This evening's 9790 kHz reception report.
Much better. :) Although the graph doesn't look really good, the audio was coming through very well (DRM radio software which I don't usually use) but with obvious audio drop outs. The text message at times was garbled, don't know if that is the fault of the receive software.
In fact when I asked my wife to come over and experience the short wave stereo, she was dancing to the music :D
As for signal strength, very strong, pinning the S meter at S9+40db plus. Trouble with such power is that the multipath is strong too. At S9+30dB there were drop outs, and at S9+20dB the audio was gone! :eek:
Don't you just love DRM?
-Zyg-
Brendan1
21-10-2006, 02:18
Well Terje, I'm afraid I don't have an answer for you on the Audio Level: I don't know that anyone over here can "hear" TDP 6015 on this side of the big pond. I certainly can't make any kind of comparison here, anyone else in NA?
Here's my report today: a good number of dropouts, looks like the very low sunspot numbers are not helping (apparently at or near zero this last week).
Had to manually start this log (again), so I missed the first few minutes... :mad:
Thank you so much for the very nice reception reports that appear every day. Oregon and Arizona are some distance away from the primary intended coverage area, so it really is nice to see that you can listen to TDPradio in stereo over there as well! We hope the little problems in the first few days are over now. Thanks for reporting them.
Ludo

22-10-2006, 02:06
Very good reception today. Some audible cutouts that didn't appear to be RF related: source issue? The speed also changed: started at 20.96, ended at 20.88. For not being in the target area as Ludo said, I'd say this is pretty good!

This evening's 9790 kHz reception report.
This was the best, so far, of all the evening TDP Radio transmissions via Sackville. The conditions were stable.
Apart from some blips, the audio was great.
The attached ID screen indicated that the stereo audio rate was at 20.96 kb/s.

23-10-2006, 04:14
Well Zyg, my dips are smaller than your dips! Wasn't here to listen, but the graphed data looks pretty good. This looks like about the best log for TDP via Sackville for me. The SNR is not the highest, but the decoded frames is about the smoothest ever for me.
This evening's 9790 kHz reception report.
Poor.
Note that the Service Label shows Sweden. :confused:
-Zyg-
Brendan1
24-10-2006, 02:19
Well, DRM Logger is not working at all anymore. I have no idea why either.
So, here is the manually started log of the last 28 minutes of today's TDP broadcast. Much like Zyg's log, not all that good for the last minutes. My service label doesn't say Sweden at least, but there was weirdness yesterday on Sackville's signal that was much the same. Dream said one thing, DRMSwR said another, but after a few minutes they synchronized finally. Odd.
Brendan1
26-10-2006, 02:33
I was able to log most of the broadcast today: an excellent dataset. Sackville had the two service channels showing, but only one audio track was actually there.
Alan Johnson
27-10-2006, 02:01
couldn't listen for long today, but great reception. The stereo balance problem appears to be better.
73,
Alan Johnson
99.87% audio WAY OUT WEST!
I also happened to catch "Shine A Little Love" by ELO done Rave style.
VERY COOL :)
Brendan1
28-10-2006, 02:18
Well, it was a little up and down today. Due to some hardware/software (and humanware) problems, this log was manually started, and not auto-started.
Doesn't look too bad either, but there were some audio dropouts heard.
Taking a 3 hour road trip today, so I'm pod-ing both this and the previous broadcast! Awesome. Thanks Ludo and crew :)
This evening's 9790 kHz reception report.
The propagation hurt the signal, note the sharp and uniform SNR decrease!

29-10-2006, 03:41
I don't think I've ever had a flatter log. Very, very few blips. This makes Zyg's log look bad... ;) Just better propagation to the western US!

Not good. :mad:

Brendan1
30-10-2006, 03:28
Zyg - whatever happened to you hit me worse: my log has no data at all. Not a single blip of a single frame anywhere on it. Whatever was going on was pretty much fatal this far west.
Brendan1
31-10-2006, 01:57
TDP started okay, but went downhill. As I was listening, a lot of audio dropouts were happening.
Brendan1
01-11-2006, 02:19
Some dropouts at the end today - propagation seems to be changing somewhat.
Brendan1
02-11-2006, 02:10
Not so many dropouts today. Good reception overall. Only the slightest ending bobble in the SNR.
Brendan1
04-11-2006, 02:10
Original posting was in error: this is what a long day of teaching will do. My computer locked up during the unattended reception and had no data.
So sorry for any confusion - just noticed it tonight (4/11/06).
Brendan1
04-11-2006, 02:12
Only a few glitches. Otherwise excellent.
Brendan1
05-11-2006, 01:03
Noticeable dropouts for the last 10 minutes or so. Up to that point though, everything was excellent.
This evening's 9790 kHz reception report.
Signal started out strong S9+40dB, and lasted for about
45 minutes before propagation took over. ;)
-Zyg-
Brendan1
06-11-2006, 02:05
Zyg - for once, your QTH stayed open longer than mine. After about 40 minutes the signal quickly dropped in strength, and the broadcast became undecodable.
Brendan1
07-11-2006, 01:04
Much better - no big dropout today.
Brendan1
08-11-2006, 02:10
Not too bad: this will work for me! :p
Brendan1
09-11-2006, 01:04
Not so good today: I think there is a certain period of ionospheric instability following sunset, and it happens during this broadcast. Today was just worse than usual, and just as the broadcast was ending it was regaining strength. :(
Brendan1
10-11-2006, 02:31
Improved over yesterday, that's for sure. Some dips, but better overall.
Brendan1
11-11-2006, 02:02
Things just weren't going my way today with this broadcast. What began well ended with basically nothing.
Brendan1
12-11-2006, 01:09
Still pretty rough on the reception. Improved over yesterday.

13-11-2006, 02:13
Another not-so-good log tonight. Propagation is off, definitely.
Brendan1
14-11-2006, 02:09
A terrible day - getting home at minute :10, the waveform was fading in and out very quickly on Dreams' eval screen. Not a very successful log.
Brendan1
16-11-2006, 01:28
I missed yesterday because Dream crashed in the morning. Today's log is not all that good either, but at least it is something!
Brendan1
17-11-2006, 01:00
Way bad today. It would appear that the band is closing much, much earlier now. By the end of the log, there was virtually no waveform visible on the Dream evaluation screen.
Alan Johnson
18-11-2006, 00:57
I got a late start listening today - now the right audio channel is lower than the left! Good results until my local sunset.
Brendan1
18-11-2006, 01:04
I can confirm the unbalanced audio - the left channel was normal, while the right was virtually inaudible. Lower sunspot number today: somewhat better reception for the first time in several days.
Brendan1
19-11-2006, 02:01
Best log in days. Conditions continue to improve on this frequency.
Brendan1
20-11-2006, 02:06
Well, just when I think everything is getting better, something like today happens.
Brendan1
21-11-2006, 01:15
Still with the up and down - guess this one is settling into a real pattern for me.:(
Brendan1
22-11-2006, 01:04
Worst log since the TDP broadcasts began.
Brendan1
23-11-2006, 01:10
Somewhat better than yesterday, but the band still died early. :(
Brendan1
24-11-2006, 05:23
Each evening this broadcast is improving - overall conditions getting better once again. A few more minutes tonight, maybe the entire hour tomorrow?
Brendan1
25-11-2006, 01:03
Sigh - another not so very good day for this transmission.:(
Even worse reception in the Atlanta area.
Brendan1
26-11-2006, 02:13
Well, I thought Sackville had missed the broadcast entirely until I looked at the logged data: one minute worth of high quality something or other at the very end. Did someone forget to check the time? In the interest of proof, here's my log.
Brendan1
28-11-2006, 01:12
Good news is that today they were on time. Bad news is that virtually nothing was heard, at least when I was present. I got home at 0007 UTC, just as everything went downhill. :(
Brendan1
29-11-2006, 01:05
Good audio for the entire broadcast. First time in days it has been this good.
Brendan1
30-11-2006, 01:07
Not so good today. :( The band was noticeably failing at the end...
Brendan1
01-12-2006, 01:04
Terrible - a burst of music just as I get home, and then the band falls apart. :mad:
Alan Johnson
02-12-2006, 01:02
The signal dropped out a little before sunset.
Brendan1
02-12-2006, 01:13
Alan - you did better than I did. Not one beat or note heard, the SNR was just too low for reliable decoding, at least when I was home to be able to listen to anything... :(
Both of you had better reception of the 9790 kHz signal than I did!
-Zyg-
Brendan1
06-12-2006, 01:15
Not much today. Miserable conditions.
Brendan1
07-12-2006, 01:40
Best reception in days - I actually got to listen to some music today. The band did shut down rather dramatically however, a little more than half way through the broadcast.
Brendan1
08-12-2006, 01:03
Still marginal: band closing right around local sunset now.
Brendan1
09-12-2006, 02:09
All of the lower bands are not performing well right now. The recent storms and flares are raising havoc... :mad:
Brendan1
12-12-2006, 01:08
Better today, but the band still shut down early.
Brendan1
13-12-2006, 01:02
Best log in weeks - propagation was excellent for this broadcast. Now watch, tomorrow, back to the same old short band opening.
Brendan1
14-12-2006, 01:13
A quick exit for the good conditions, but better than virtually every other broadcast I've logged today.
Brendan1
15-12-2006, 01:15
Another rather lousy day of logs. :mad:
Brendan1
16-12-2006, 01:09
Nothing on the air today - no analog, nothing. :(
Brendan1
19-12-2006, 01:21
The return of TDP, and it wasn't all that bad (if you completely ignore the big dropout in the middle). :rolleyes:
Brendan1
20-12-2006, 02:28
Not so good today...in fact damn lousy. :mad:
Brendan1
21-12-2006, 02:02
This broadcast has gone from being one of the best to one of the worst, at least for me. Haven't had a truly excellent log in weeks now.
Brendan1
22-12-2006, 02:06
From bad to worse: compare yesterday's log to todays. :(
Last log for the holidays - leaving town and gear behind until after the new year.
Brendan1
09-01-2007, 01:19
A pretty good log today - not a lot of problems. The band closed early, but this is still later than it has been in the last few weeks.
Brendan1
10-01-2007, 01:34
From a moderately good day to a lousy one. :( I was here, listening and watching, and the band just faded away.
Brendan1
11-01-2007, 02:51
Wouldn't you know it, but the day I'm not home until later is when virtually the entire hour is audible. :mad:
Brendan1
12-01-2007, 02:12
The band went away, so the broadcast did too! :(
Brendan1
13-01-2007, 01:09
TDP lasted a little longer today, but the band faded away again... :(
Alan Johnson
14-01-2007, 02:15
Bad, bad, bad. Based on how I received CRI at 0100 UTC on 6080 kHz today, maybe this transmission should shift to a lower frequency.
Alan
Brendan1
18-01-2007, 01:23
TDP began dropping in/out around 0045Z, otherwise it wasn't all that bad. I don't know that dropping the frequency to 6 MHz would accomplish anything for me at least: it may be too low for this time of day for good reception at my QTH. I think it is mostly a matter of the grayline doing mischief at the end of the day. Not much can be done by anyone to change that from happening. :(
Brendan1
19-01-2007, 01:09
Pretty much the same as yesterday: in and out. :( It truly looks like the band just isn't cooperating right now.
Brendan1
20-01-2007, 01:19
Somewhat better today, although there were lots of little 'hits' in the audio while I was listening. Overall the graph looks better tonight, but the closing few minutes saw a quite dramatic drop in signal strength.
Brendan1
21-01-2007, 01:05
Really good today! Best day in weeks for me, since the band didn't close early.
Brendan1
22-01-2007, 03:36
Not so good today. :mad:
Brendan1
23-01-2007, 01:12
The band is returning to it's former condition: closing before the broadcasts' end.
Brendan1
24-01-2007, 01:55
Extremely variable tonight, not much stability.
Brendan1
25-01-2007, 01:12
Boy, the band shut down very early and very fast tonight. :(
Brendan1
26-01-2007, 01:13
Better today, with the band shutting down only a few minutes before the end of the transmission.
Brendan1
27-01-2007, 01:10
Not good. A very quick end to the decoded audio, and the band closed extremely early. :(

29-01-2007, 01:03
Best log in several months. Only some very minor blips, otherwise the entire hour was audible. A very nice change from the norm.
Alan Johnson
29-01-2007, 01:57
Has the new solar cycle started? My best reception in months as well. Too bad I had an errand to run and couldn't actually listen to the program. :mad:
Alan

30-01-2007, 01:05
Took some hits today, and I was so hoping it would be trouble free. Overall the trend seems to indicate that this broadcast is slowly improving with the lengthening of daylight now.
Brendan1
31-01-2007, 01:34
I would say that this broadcast is showing some steady signs of improvement. I'll cross my fingers and hope that it continues to improve.
Brendan1
01-02-2007, 01:14
Not very steady tonight. A lot of cutouts for the last 40+ minutes.
Brendan1
02-02-2007, 01:11
Forty minutes of fairly good reception tonight, but not without dropouts to the signal.
Brendan1
03-02-2007, 02:13
Not one listenable moment tonight, at least in the time that I was home and able to listen.
Brendan1
04-02-2007, 01:09
Much better tonight. At least 45 minutes of listenable audio. The band is in better shape, at least for letting good signals come my way.
Brendan1
05-02-2007, 01:02
Very sporadic, that's the best thing I can say about today.
Brendan1
07-02-2007, 01:02
Yesterday Dream crashed just after I left for work - no log. Today, things went much better, and the broadcast was audible for nearly the entire hour.
Brendan1
08-02-2007, 02:16
Not bad today, some dropouts towards the end of the broadcast. The band appeared to be closing a little earlier, at least for today.
Brendan1
09-02-2007, 01:08
A near repeat of yesterday: excellent up until the last few minutes.
Brendan1
10-02-2007, 01:07
Truly great today: audible all the way to the end.
Brendan1
11-02-2007, 01:07
Hmmm, DRM Logger didn't shift frequencies per setup, so I missed the first 26 minutes. I had been fooling around, so something could have been messed through "operator error." :rolleyes:
Otherwise, excellent tonight.
Alan Johnson
11-02-2007, 02:20
I tuned in late but the transmission held up until closing.
Alan Johnson
12-02-2007, 15:37
Wow! I think this could be my best.
Brendan1
13-02-2007, 01:08
100% today, which is the first time in a long time. Longer days - longer band openings? :)
Brendan1
14-02-2007, 01:12
Very nice again, except for the big "dip" just after the beginning. I've got no theory as to what happened...
Brendan1
15-02-2007, 01:09
Back to 100% today. I just wish I could listen for the entire hour...
Brendan1
16-02-2007, 01:13
Another good, solid log today. :)
Brendan1
17-02-2007, 01:06
Steady again today, but there were some audio dropouts while I was listening, all of which were extremely short.
Brendan1
18-02-2007, 01:02
Woo Hoo! 100% again! I heard no dropouts, no audible faults today. Nice to have this broadcast back up to the max again.
Alan Johnson
18-02-2007, 01:56
Simply wonderful for the first 45 minutes, then things got shaky. In retrospect, I should have tried a different antenna.
Alan Johnson
19-02-2007, 02:07
I had reception for the entire hour today with a lower noise antenna.
Brendan1
19-02-2007, 02:14
Another great day!
Brendan1
20-02-2007, 01:08
Some winter lightning caused a few dropouts around minute :47 and detracted from the overall quality today. Otherwise, pretty darn good.
Alan Johnson
20-02-2007, 02:04
Late start, but the signal held up well.
Brendan1
21-02-2007, 01:09
Excellent log today: 100%. No dropouts...
Brendan1
22-02-2007, 03:00
Some wobbles today, not perfect.
Brendan1
23-02-2007, 02:08
Only about 4 very, very short dropouts heard today.
Brendan1
24-02-2007, 01:40
100% today!
Alan Johnson
24-02-2007, 02:10
99.77% CDA, but 100% to my ears!:D
Brendan1
25-02-2007, 02:09
A few minor, audible hits today, nothing big. Otherwise, it was excellent!
Alan Johnson
25-02-2007, 17:55
Overall very good - things have improved.
Brendan1
26-02-2007, 02:02
Pretty good tonight - I won't complain. :)
Alan Johnson
26-02-2007, 02:02
Good for the first half then things went downhill, switching antennas didn't help. Can I blame it on the snow we're getting?
Brendan1
27-02-2007, 01:09
Perfect flat-line log today: 100% again. :D
Brendan1
28-02-2007, 01:07
DRM as it should be: rock solid copy!
Brendan1
01-03-2007, 01:08
100% again, although it's not absolutely a flatline graph. No audio heard at minute :08, only hissing (at full volume). By minute :22 when I checked again there was audio present.
Brendan1
02-03-2007, 01:45
Some local noise caused most of the problems towards the end of the broadcast, and I don't know what was causing it. :mad:
Alan Johnson
03-03-2007, 02:17
Great for the first 50 minutes, then downhill.
Brendan1
03-03-2007, 17:12
No problems here, unlike Alan's QTH.
Alan Johnson
04-03-2007, 01:01
Not too bad today - at least I caught the whole hour.:)
Brendan1
04-03-2007, 01:50
Some audible hits the last half hour, but they were all extremely short.
Brendan1
05-03-2007, 01:05
Boy, this is a terrible log. Not one moment of decoding. All I can think of is that the ionosphere took a hit today sometime. Very disappointing.
Alan Johnson
05-03-2007, 01:13
Back to the "good for the first 45 minutes" routine. :mad: I don't know why the frequency/location info didn't picked up by Dream's log file.
Brendan1
06-03-2007, 01:26
Now it's time for TDP to go bad on us... Not a good day. :(
Brendan1
07-03-2007, 01:20
Much, much better today. :)
Brendan1
08-03-2007, 01:28
The goodness continues...
Brendan1
09-03-2007, 01:09
Perfection today: 100%!
Brendan1
10-03-2007, 02:11
This broadcast was impossible to listen to today. The SNR figure was all over the place, and the audio decoding was not at all steady. I can only blame propagation, as other broadcasts were quite good this afternoon.
Brendan1
13-03-2007, 01:53
Much better than my last log - quite good up until the last five minutes and then very audible hits were occurring.
Brendan1
14-03-2007, 01:08
Continued excellence in reception for TDP.
Brendan1
15-03-2007, 02:24
Some hits today: I heard them, and the log shows them.
Brendan1
16-03-2007, 01:14
Not perfect, as I heard some small glitches.
Alan Johnson
16-03-2007, 02:07
Only caught the last eleven minutes, but not bad as it's usually the last quarter of the program that drops out.
Brendan1
17-03-2007, 01:02
The CDA may say only 99.99%, but I did not hear the missing 0.01%. :)
Alan Johnson
17-03-2007, 02:00
Very good today - ignore the CDA, as I wasn't around to turn off logging.
Brendan1
18-03-2007, 01:03
I thought this would be perfect, but the last 10 minutes saw some real hits. High 90% range is still quite good though. :)
Alan Johnson
18-03-2007, 02:38
I had high hopes as well, only to have them dashed in the last ten minutes.
Alan Johnson
19-03-2007, 01:47
Excellent results today.
Brendan1
19-03-2007, 03:55
Pretty dang good, as usual. :)
Brendan1
20-03-2007, 01:20
This was great! Didn't hear any glitches while I was listening, and the log agrees! :D
Brendan1
21-03-2007, 02:06
Some hits towards the end, but otherwise very good reception yet again.
Brendan1
22-03-2007, 01:09
Some small hits today. Not bad otherwise.
Not so good here in Cheese Country as in Brendan1 Land, ;) but some audio seeped from the back lobe during the first 38 minutes. The first 13 minutes shows 98% decoded audio. During the period from 0024-0035 UTC there was about 83 % decoded audio.
The log was unattended.
mitajohn
23-03-2007, 01:03
Hi all,
A problematic result compared to the one on 9800 kHz.
Brendan1
23-03-2007, 01:25
Another fine day's log, with only minor fluctuations.
Brendan1
24-03-2007, 01:13
Mother Nature spoiled my log: lightning moving through the area today. Logs like this are no fun... :mad:
Brendan1
25-03-2007, 02:05
No lightning, only a slightly dying band at the tail end of the broadcast. :o
Brendan1
27-03-2007, 02:08
Best log of the day so far. Plenty of disturbed conditions to go around.
Brendan1
28-03-2007, 02:48
Quite a few glitches in the audio today, propagation is definitely off.
Brendan1
29-03-2007, 02:25
Somewhat better today, but still not error free, either by ear or data. A nasty drop at the end too... :(
Brendan1
30-03-2007, 02:03
Much, much better: nearly perfect today. :D
Alan Johnson
31-03-2007, 02:03
A late start and a couple of dips in the audio, but I'll take it :D
Brendan1
31-03-2007, 04:16
Things are getting better on the bands the last couple of days. This log is rather better... :)
Alan Johnson
01-04-2007, 02:03
Held up for the entire hour - no foolin'. ;)
Brendan1
01-04-2007, 02:26
Same as Alan - an entire hour is always good! :D
Alan Johnson
02-04-2007, 02:06
A bit worse today, but then the A index is 27 and the K index is 3. China was coming in well at the previous hour on 9800 kHz. According to the Sackville links on the DRM schedule page, 9800 uses a beam of 268 and 9790 has a more southerly beam of 227 degrees - I wonder if this explains the difference?
Brendan1
02-04-2007, 03:54
Alan et al, I've seen those different azimuths for the two broadcasts and my theory is this: a majority of immigrants from China live in western Canada and the western US, ergo a desire on the part of Radio China to provide coverage for them rather than the East Coast exclusively. Just my 2 cents worth.
Pretty good tonight, only a couple of dips for TDP.
Brendan1
04-04-2007, 02:11
Yesterday was not a good day: I screwed up DRMLogger and had no logs. :rolleyes:
Today everything went much better, and TDP came through as always.
Brendan1
05-04-2007, 02:35
Another fine log for TDP, although I've not had a perfect dataset for sometime now. :o
Alan Johnson
06-04-2007, 02:00
Another good day!
Brendan1
06-04-2007, 02:04
As Alan said, another good day! Same story here: another excellent log. :D
Some spill into Europe, but not enough for decoding. I'm not exactly in line with the antenna beam. ;)
Brendan1
07-04-2007, 02:04
The "good" continues: very steady today, although there were some minor cut-outs to the audio. :)
Alan Johnson
07-04-2007, 02:16
Not as good for me today - glad I took the dogs for a walk about 0025!
Brendan1
08-04-2007, 03:05
Pretty good today, only about 3 hiccups heard the entire hour.
Brendan1
09-04-2007, 02:00
Two very short glitches, otherwise excellent reception today.
Brendan1
10-04-2007, 02:10
Just enough glitches to keep it from being perfect today.
Brendan1
11-04-2007, 02:24
Very consistent again today. No complaints.
Brendan1
12-04-2007, 02:53
Lots of variability today: while trying to listen and watching the waterfall, the propagation looked to be quite disturbed, with lots of dropouts. :(
Zero audio decoded, although pretty good signal level here. I love TDP's music. Too bad it's skipping over me!
Brendan1
13-04-2007, 02:47
Very good as usual for me. Only one major blip and a couple of small ones to mar the CDA today.
Brendan1
14-04-2007, 02:04
Another nice day for TDP. I did hear some cut-outs to the audio, but nothing to scream about. :rolleyes:
Brendan1
17-04-2007, 02:07
Short cutouts to the audio, but otherwise pretty good.
Will be logging HCJB all day tomorrow. A long test to western NA for them, and I'm in the path... :o
Alan Johnson
22-04-2007, 02:06
Took a break from HCJB to listen to TDP. Did well today.
Alan Johnson
23-04-2007, 06:11
Nice signal strength, too bad there was no audio (confirmed by my monitoring at around 0020 UTC):(
Alan Johnson
25-04-2007, 05:22
Looks like a good signal, but no audio again.
Alan Johnson
27-04-2007, 04:25
The graph looks good, but I didn't hear any audio when I came home from work.
Alan Johnson
28-04-2007, 04:20
Terrible until I switched to the dipole. This was a semi-attended logging and there was definitely audio today. (Date is wrong on the graph because I started recording before 00:00 UTC).
Alan Johnson
29-04-2007, 02:54
Fairly good results today.
Alan Johnson
30-04-2007, 04:31
Very poor results today-a 10 kHz shift in frequency shouldn't make much difference. There's also a 9 degree shift in the beam; maybe it's just the time of day.
Brendan1
02-05-2007, 04:07
Nice log today. :) I won't complain about the results.
Brendan1
03-05-2007, 04:04
Continued excellent results! Not railroad tracks, but only slight squiggles. :)
Brendan1
05-05-2007, 02:12
Another great log today. Propagation is nice and steady right now. :)
Brendan1
06-05-2007, 02:06
Really good, although just under 100% today. I don't know why the log recorded 9800 as the frequency: it was definitely on 9790 today. Just another glitch...:rolleyes:
Brendan1
07-05-2007, 03:22
Oh so close! A couple of glitches kept the log from reaching DRM nirvana. :rolleyes:
Brendan1
08-05-2007, 02:26
Not very good at all today. :( I have no explanation as to why it was so bad either...
Not perfect but not bad either
Brendan1
09-05-2007, 02:04
Pretty good today - not flatline graphs, but close. :)
Noticeable audio interruptions this evening.
Brendan1
10-05-2007, 04:58
Pretty good today, just missed 100%, again! :D
Brendan1
11-05-2007, 02:47
Once again this broadcast does very well at this QTH. :)
Brendan1
12-05-2007, 03:00
Another excellent day! :)
Brendan1
13-05-2007, 02:12
I didn't hear anything go bad today in spite of what the log shows. Excellent conditions today.
Alan Johnson
13-05-2007, 02:13
Good results here, as well. I had the same dip Brendan did.
Looks like we all experienced the dip near 0034Z.
Alan Johnson
14-05-2007, 02:02
Nice signal - too bad Winradio decided to hiccup:mad:
Brendan1
14-05-2007, 02:06
That's two of us with hiccups: mine was at 00:49 and it was my computer doing something unknown but CPU intensive. :mad:
Otherwise, very good once again. :)
Brendan1
15-05-2007, 02:07
Good, but there were some audible hits of course, what with the log showing some ups and downs. Most of my logs for today show fairly rough conditions.
Brendan1
16-05-2007, 02:06
Another excellent day. :)
Pretty solid here also :)
Brendan1
17-05-2007, 02:27
Pretty solid today, only some very minor bobbles to mar the CDA... :o
Brendan1
18-05-2007, 02:03
Some new unidentified noise source killed my log today: I could see it come and go on the waterfall. :mad:
Brendan1
19-05-2007, 03:12
Quite good tonight. The local interference was only temporary, it would seem. :)
Brendan1
20-05-2007, 03:46
Continued goodness...:)
Brendan1
21-05-2007, 02:04
Extremely variable - the periods of decoding didn't last very long unfortunately. :mad: The graph looks better than it sounded...
Alan Johnson
21-05-2007, 02:04
This was TDP, despite what the service label says (it switched to the correct label during the first minute). A bit uneven today.
Brendan1
22-05-2007, 04:07
Better than yesterday by far, but not without some small errors. :)
Brendan1
23-05-2007, 02:33
I think the three bigger dips are my computer's fault - it was acting a little stressed when I got home during the broadcast. :rolleyes:
Brendan1
24-05-2007, 04:17
Some rather large dips about half-way through. :(
Brendan1
25-05-2007, 02:14
Lots of quick, little dropouts today during the first two thirds, and they seriously detracted from the overall quality.
Brendan1
29-05-2007, 02:01
Only two audible glitches today, otherwise excellent today. :)
