Cut this log short to collect some data on RNW Bonaire today. Better earlier than on other days, but the CBC still needs to tweak things for better coverage of North America, not just the "North East USA." There are more than a few of us DRM listeners who aren't within a few hundred miles of Sackville...
Here in Bremen it looks like that:
Cool DX :)
Left of bar: DW. Right of bar: Radio Sweden
22441
Yesterday's reception report...
Big DX - small antenna :)
22500
22501
Didn't know that mit litle antenna is so good :D
It's comparable:
22547
Left of bar: DW, right of bar: Radio Sweden

Quite good results last night.

I don't usually bother collecting data on the CBC because it doesn't come in very well most of the time. Today, however, it was coming very well so I copied an hour's worth. The signal was still up and down, but at higher SNR (about 6 dB) than normal. I know the solar flux is up and that may be the big change.
Brendan1
24-08-2006, 23:04
Instead of the last hour, here's a log of the first two. Rather typical for my location and time of day.

I listened to 9800 kHz from Sackville last night.
Probably somebody forgot to switch the antenna to the US, telling from the signal strength it was beaming to europe. :confused:
Brendan1
25-08-2006, 23:58
Much better than usual for CBC. There was lightning over the last hour or so, that's where a lot of the drops come from. As always for my QTH, the last hour is the best hour.
Brendan1
28-08-2006, 04:18
The rest of life got in the way of the hobby, hi hi. Last two days logs of 9800, and they both show very similar results. Kind of spaced out today, and forgot to turn off the logs at the end. :rolleyes:
Brendan1
29-08-2006, 00:52
Probably the best log for CBC for me, certainly the highest SNR (21.4) I've had at this location for any DRM broadcast. Conditions were good too, since quite a bit of the broadcast was audible.
Also, if anyone at CBC is listening, the SDC was totally out of whack. It simply read "Radio", was "pop music," and "BE" was displayed as originating country. I don't think Radio Sweden counts as coming from Belgium... Sounds like it was somehow still setup for the TDP broadcast on Saturday. Text was okay, the usual "coming from CBC...to NE USA," et cetera.
Brendan1
30-08-2006, 00:56
Lightning later in the log, so blame some of the dropouts on that. Not as high an SNR as yesterday but still quite good.

Hi all,
A weak signal, but the result was quite good.

Lousy day. No QRN either. No explanation for the mediocre conditions. Not to mention the incredible drop in SNR around 2200Z.
Today's 9800 kHz reception report. Pretty good.
Brendan1
02-09-2006, 05:14
Zyg - you're right on. This was a good day here, but I am actually jealous of your fine reception over there in Georgia. I would hazard to say the lengthening days have a lot to do with it.
Brendan1
03-09-2006, 01:05
Up and down, that's todays' log. Not much to say about it otherwise.
Brendan1
08-09-2006, 00:42
Been off monitoring RNZI's broadcast during this same time frame for the last few days. About normal, although as we get closer to the equinox the last hour or so has a higher SNR than during the height of summer.
This afternoon's reception report. Very good.
The blips in the first 15 minutes were my fault. :o
-Zyg-
and it is obvious from this 2 day log. Oh well :(
Brendan1
15-09-2006, 00:50
Just about an all-time great log for the CBC at this QTH. Conditions are improving well, and the propagation indicators are good too: 85 SFI and 1 K.
Brendan1
16-09-2006, 00:23
Yesterday: very good. Today: not so good. Latest SFI: 80, latest K is 0. I think it's all in the numbers...:(

As usual, I'm jealous of Zyg's signal levels. Here's the western US report for today. Not bad, better than yesterday.
Brendan1
23-09-2006, 00:54
This is the all time high SNR for my location and gear. I've never hit 21 dB before for any broadcast. Always near, but not quite until today. It was also very good solid reception for the time period, not just a good SNR. Must be the equinox.
Brendan1
24-09-2006, 00:51
Fantastic log today. With the shorter days, it just gets better and better out here in the west. Have to admit I missed the first 47 mins - was doing something else...
Here is this afternoon's 9800 kHz log.
Brendan, looks like your reception is getting close to what we get in the south east! ;)

Not as good as last week, but not all that bad either. An average day in other words. :o
The afternoon 9800 kHz reception report.
The ID screen was showing 11900 kHz.

Brief time for listening today, but good results.

I get the 11900 data too. Amazing how those things keep going...:rolleyes:
Not all that good today: too much propagational variability and the log shows it.
Brendan1
04-10-2006, 01:26
Pretty good log today. Good signal strength, good SNR.
Brendan1
07-10-2006, 00:52
If I was two or three timezones further east, reception would probably be perfect... :rolleyes:

Hi all,
A pretty good result from this weak TX.
John.
Brendan1
09-10-2006, 00:55
Only an hour logged today, but about as good as it gets here.
Brendan1
11-10-2006, 00:54
Not very good to start, but it ended well. There was no audio during the DW broadcast from 2200 to 2230Z, had to check my connections to make sure it wasn't me: it wasn't. RSI came in just fine at 2230Z until the close.
Brendan1
12-10-2006, 00:49
Whole thing today. Some audible drops, but that's typical.
Brendan1
13-10-2006, 00:48
Off getting oriented for new job, so this was auto-logged. Judging by the log, pretty good results today. More up time than down.
Brendan1
14-10-2006, 00:39
Judging by the log, a really good day for the ol' CBC. Good decoding, and a very respectable SNR (for me). It does look like the transmitter went off-air at 2131Z, a double dip as it were.
Alan Johnson
15-10-2006, 01:13
Very good today - dip at approximately 40 minutes is from me monkeying with the sound card mixer program.
Brendan1
15-10-2006, 02:05
Not all that bad today. Some up/down on the SNR, but not unheard of for this frequency.

16-10-2006, 00:11
An average reception day here. Lots of disturbance.
RCI was showing a second channel during Radio Sweden's broadcast today. Labeled "GDW" which I took to be Deutsche Welle, the SDC showed as an English language current affairs broadcast. No audio found when I clicked on it, just more of that high fidelity digital silence. I've never seen this before from RCI.
CBC switched channels at each program change. Labels were "Vatican Radio", "RCI", "RNW", "GDW" & "Sweden". Example: if RCI was on channel one, at switch over, RNW was on channel 2.
I was using an FM modulator and listening upstairs. When the switch happened, DReaM stayed on channel one and I had to run downstairs to manually switch to channel 2 for the RNW feed. Interesting, but a bit odd. The "unused" channel at the time consisted of Brendan's Patented "high fidelity digital silence". :confused:
Hi Chris,
no problem using FhG SWR during RNW, it automatically changed to service 1 as this was the only service in the configuration. It was a wanted feature in Dream to play the last service again after a sync loss, but noone probably thought of such a strange configuration, one for the Dream forum though.
Simone
This afternoon's 9800 kHz reception report (partially attended).
I noticed that at 22:00 after the RCI program, the ID screen said no service, and the 2nd audio button showed that the DW service was there. I clicked the button and the audio returned. I was not present for the RNW switch, nor the Radio Sweden switch.
I don't know why there is an audio gap in the last half of the DW program.
The Service Label as logged by the Dream software shows TDP Radio for some reason.

Brendan1
23-10-2006, 04:20
I can report the same two channel funny business from Sackville. I wasn't around to fully note all the changes like Zyg, but I do know that while Vatican Radio was on that there was only one channel. The two channel situation showed during the RCI segment, and was showing GDW (which had no audio). Later it was showing Sweden and GDW, with GDW selected but the Swedish audio coming out. Towards the end of the entire broadcast I had to manually switch DRMSwR back to the Swedish channel to get the audio. Must be the cold weather in the Maritime Provinces... Since my graph doesn't show what speed, I am going to assume that CBC was changing the data rates.
Tonight I tried with the MP40 for the first time since they use the new configurations, no problem on Radio Vatican but MER only about 14dB due to strong AM co-channel interference from CRI, not much audio decoding.

RNW from Sackville.

Some problems, an analog signal was received until 20:52, then no audio until 21:09. I did not record the entire transmission.
-Zyg-
Brendan1
30-10-2006, 03:35
An excellent log for me. About the least erratic Sackville log ever here at my QTH. Cut it short to get the new RNW broadcast at 2200Z.
Brendan1
31-10-2006, 01:59
Again, another high quality day. Conditions are excellent for this frequency and time!
Brendan1
01-11-2006, 02:08
This freq and time continue to be good to the western US, I just wish I was able to be home to hear it this well!
Brendan1
02-11-2006, 02:04
More fluctuation today, but overall a very good log.
Did anyone notice that DW was in Stereo today? Is this normal? At 2329 they switched to Sweden with a very light audible tick and audio went to mono.
Sadly, DW was nearly all talk/news with only snips of their in/out theme obviously stereo.
Brendan1
03-11-2006, 02:29
Can't confirm the stereo or not - was still at work then. The earlier hours are continuing to look good on the log here.
Brendan1
04-11-2006, 02:20
Great signals today. Nice and flat on the SNR.
Indeed DW is now in Stereo!
Brendan1
04-11-2006, 23:54
Yes, DW stereo is quite nice, but there is not enough music to truly enjoy it. As Chris said, only the filler pieces truly come across as stereo.
Brendan1
05-11-2006, 23:48
Great as always - the magic DRM bubble still resides over the southwest. :rolleyes:
Brendan1
07-11-2006, 01:10
Good log today. No real issues seen.
Brendan1
08-11-2006, 02:06
Ho-hum, another excellent day of reception. :D
Brendan1
09-11-2006, 02:02
Pretty good, again! The stability of this broadcast is nice to see.
Brendan1
10-11-2006, 02:25
Stable and clean: a good day, but for the problem at the beginning.
Brendan1
11-11-2006, 02:05
Nice and steady today.

14-11-2006, 02:02

Brendan1
16-11-2006, 01:32
This transmission has returned to a much better reception level. Some ups/downs, but all right otherwise.
Brendan1
17-11-2006, 00:56
Pretty good reception today. I don't know what caused the big dip after the start.
Brendan1
18-11-2006, 01:08
Almost back to "normal." Much better reception today.
Brendan1
19-11-2006, 02:04
Best log in weeks - this one is longer than those I've been posting for a while. Since the RNW Montsinery broadcast is off-air for a time, I'm extending my log for this one.
Alan Johnson
20-11-2006, 01:59
I wasn't around to listen to the last hour - looks like that was a good thing.
Brendan1
20-11-2006, 02:05
Overall, it was a good day. I agree with Alan though, the last hour was not very good. Our logs look pretty similar. I do not know what the big drop after the beginning, no apparent glitches here.
Brendan1
21-11-2006, 01:12
Rather good log today.

Nice graph - I'm not sure I like the new programming, however. Switch from English to Russian at 1605.
Alan Johnson
02-12-2006, 19:03
Rough start - although audio had fewer dropouts than graph indicates. Repeat of "Blink" program from 1500 UTC, then repeated again at 1800.
Brendan1
02-12-2006, 21:29
I had to reboot the computer a little ways through, so it necessitated two parts. Interesting propagation during our local mornings/mid-day period.
I only got audio decoding during the Ukrainian part of the transmission. Seemed problems from yesterday have been solved, no more problems with the different configurations (toggling between different services) anymore today, btw Ukrainian language was signalled as Russian.

Good reception of the "Mapleleaf Mailbag" program.
After I did not get any audio decoded on RCI´s broadcast via Flevo, I got much better results on this transmission. I could listen to most of the "MapleLeaf Mailbag" (btw with Mark Montgomery again, specialist for German words ;)), especially the second half was OK for listening. Later also a pretty good period duiring the Ukrainian language program (but signalled as Russian!).

Due to a computer behaving badly, this is my only log today. Kind of a miserable log too, at that.
Brendan1
06-12-2006, 01:10
The computer behaved today, and logged the two sessions on 9800 without any problems. Fairly disturbed conditions today.

Two logs today, but I'll have only one tomorrow: TDF will be broadcasting during the NA morning hours, so I'll be logging that one from Montsinery. Sorry CBC!
Both logs are very good. I have no idea what caused the incredible dip during the first broadcast.

My wealth of superlatives is running out: another excellent log.
Brendan1
16-02-2007, 01:16
Still great: no problems again.
Brendan1
17-02-2007, 01:15
The continued good logs for this portion of Sackville's broadcast continue: this is about the longest period of time I've observed that it has been this good (last couple of months).
Brendan1

Morning and afternoon broadcasts today. The morning was definitely off, the afternoon quite good again.
Alan Johnson
18-02-2007, 01:54
I started monitoring late, but got great results.
Brendan1
19-02-2007, 02:18
30 minutes late getting started in the morning, but the band was sure crazy. The afternoon wasn't much better either, with this log being the worst in weeks.
Alan Johnson
19-02-2007, 02:25
I only monitored the morning transmission, but did pretty well - not sure what all the small dips are.
Brendan1
20-02-2007, 01:02
Much better today, more stable conditions obviously.
Brendan1
21-02-2007, 01:02
Conditions got even better today, another great log: nearly 100%.
Brendan1
22-02-2007, 03:02
Some off conditions today, no perfection this time.
Brendan1
23-02-2007, 02:09
A couple of big hits, but otherwise pretty good.
Not too bad today here in Germany during RCI´s French broadcast.

Two logs today: the morning was not as good as Simone's log, but the afternoon was much more stable. (RFI Montsinery was not on schedule so I logged CBC in the morning instead)
Alan Johnson
24-02-2007, 02:07
Excellent reception of the afternoon broadcast today. I'll take 99.8%:cool:
Hi all.
Very short log I tune up on freq.9800 and DRM play good this was last 12min. from transmission stop.
:)
Some decoding during the French programming from RCI, not so bad during the last 20 minutes of Vatican Radio.
Simone
Btw, two threads about the same transmission merged.
Brendan1
25-02-2007, 02:14
This morning's log is a little short, and shows how the band is fairly crazy, at least in the morning. The afternoon is much stabler of course.
Alan Johnson
25-02-2007, 17:54
Good reception - presented in two parts due to computer shutdown.
Alan Johnson
26-02-2007, 02:00
Very good results today for the afternoon transmission.
Brendan1
26-02-2007, 02:04
Crazy conditions this morning, but better this afternoon.
Brendan1
27-02-2007, 01:07
Pretty good, not perfect but certainly an acceptable log. The big blips I do not know about at all, but given the dips in the SNR, possible xmitter drops?
mitajohn
27-02-2007, 23:07
Hi all,
The log started with some problems then between 22:10 and 22:35 I got a very good result but after that the signal turn very weak and kept from decoding.
Brendan1
28-02-2007, 01:03
Nice log, very "flat" graph. :)
Brendan1
01-03-2007, 01:09
Not bad, some hits can be seen in the log.
Brendan1
02-03-2007, 01:43
Extremely variable today: worst log in weeks. :(
Alan Johnson
03-03-2007, 02:16
Very good results today.
Brendan1
03-03-2007, 17:14
A slightly rocky opening, but otherwise very good.
Did you notice that DW never came up for the half hour stereo slot? CBC played Canadian born rockers... Neil Young, Bruce Cockburn, etc.
Nice change of pace :)
Got some audio from RCI´s English program yesterday.
Simone
Brendan1
04-03-2007, 23:59
Morning and afternoon broadcasts. Both are suffering from something, most likely a reluctant ionosphere.
Chris - no, I missed the goof. It does make me wonder how Sackville manages to keep running though... :p
Brendan1
06-03-2007, 01:24
A much better log for the afternoon than other days of late.
Brendan1
07-03-2007, 01:19
A nice, solid copy log today. :)
Brendan1
08-03-2007, 01:33
Very rocky today, not too stable.
Brendan1
09-03-2007, 01:08
Better than yesterday...
mitajohn
09-03-2007, 23:05
Hi all,
A good result from a TX ~7000 km away, until strong co-channel QRM appeared and killed DRM, so I stopped from logging.
Brendan1
10-03-2007, 02:08
Rather a good log I say.
Reception at Paris.
Daniel
Brendan1
13-03-2007, 01:51
One tiny little blip to drop the overall CDA rate to 99.99%! :p
Brendan1
14-03-2007, 01:06
Some bad moments today, but otherwise rather a good log (as usual).
Brendan1
15-03-2007, 02:22
Nothing to complain about today. :rolleyes:
Brendan1
16-03-2007, 01:12
A bit rough at the beginning today.
Brendan1
16-03-2007, 23:51
I think the upcoming spring equinox may be driving some of the band changes, and 9800 is not immune.
Brendan1
18-03-2007, 00:19
Best log in several days.
Alan Johnson
18-03-2007, 02:43
Good reception here today, as well.
Brendan1
19-03-2007, 03:53
Overall, not bad but the dip in the middle...
Brendan1
20-03-2007, 01:18
This looks better, like the band is behaving itself once again.
Brendan1
21-03-2007, 02:04
A very good log today, albeit with a couple of rough spots.
Brendan1
22-03-2007, 01:08
A bad patch at the beginning, otherwise very good.
mitajohn
23-03-2007, 00:08
Hi all,
A good to very good result tonight.
Brendan1
23-03-2007, 01:23
A bit of a slow beginning, but otherwise excellent.
Brendan1
24-03-2007, 01:11
Very, very, marginal today. Mostly due to lightning in the area. :(
Next log on the 25th will be longer, as I will no longer be logging RNW on TDF, as they are shifting frequencies and time. :)
Brendan1
25-03-2007, 02:02
The longer log debuts. Not all that bad (no lightning today), the band was a little slow to get going at first.
Alan Johnson
26-03-2007, 00:08
I'm confused - I set things to switch from 9800 kHz to 9750 kHz at 2300 (to switch from CBC to R. Vatican) but nothing decodable on 9750 and now R. China Intl. is on 9800 at 2300. Not too bad for what I did capture today.
Brendan1
26-03-2007, 02:55
Alan - I saw that switch too, but the VR 9750 is direct, shifting there from 7370. The RCI threw me for a minute, but not too long.
Too lazy to log today... :)
This is one of the strongest signals into my location, +40 signal strength.
Decode is about 30db and the signal is very clean and flat.
17.1kb/s
Even with all this power I still get occasional audio drop outs. It must be the path length?
The DRM directory shows this site still broadcasting to NE USA at 1730 but the signal is horrible. The signal is just out of the noise floor and decode is about 8db. 10% audio reception.
For some reason this site propogates very poorly to New England. Even when the RF signal is strong it's subject to selective fading and audio drop-outs
70Kw
There is an analog signal right on 9800 Khz comming in also. To weak to make it out. Sounds Chineese?
Brendan1
27-03-2007, 01:51
Jeff - you may be too close to Sackville to get steady reception. At times, the signal may be actually going over your location in Rhode Island, and you are actually getting only a marginal signal. This happens quite a bit with HF, especially with sites within about 1000-1200 miles. 9800 is also a bit high for short range work as well, and for your situation 7 megahertz might be better, but they're not going to change frequencies for just one person...unfortunately.
The skip zone results when the signal is going up to the ionosphere, reflecting off the appropriate layer, and then coming back down to the surface far away. A typical signal will do this several times over thousands of miles for just one transmission. In past experience, I found that one could be within visual range of the transmitters and practically hear nothing at all, that's how good they can be at getting the signal up into the ionosphere.
I hope this helps...
Brendan1
27-03-2007, 02:03
Wow! Lots of ionospheric issues today. A rather poor log I'm afraid.
Brendan1
28-03-2007, 02:46
Messy today: not very good. :(
Brendan1
29-03-2007, 02:27
Still messy today. Lots of ups and downs, including what looks like three transmitter cut-outs.
Brendan1
30-03-2007, 02:05
A rather slow, not-very-good start today that later became quite good.
Alan Johnson
31-03-2007, 01:22
Good results today. I can't get Dream and DRMCalc to read my receiver co-ordinates, even though they are correct in Dream.ini.:mad:
Brendan1
31-03-2007, 04:10
Fairly steady today, no real bad periods, just a few variations in the SNR.
Alan Johnson
01-04-2007, 02:01
Not sure what the little dips are (they were there yesterday as well), but a 99.3 % CDA is OK by me.
Brendan1
01-04-2007, 02:24
Morning and afternoon logs today, and frankly, the morning log is pathetically bad. The afternoon is a lot better, but I missed logging the first hour or so. :)
Hi,
quite good this night (local time in Europe)
Bernd, DF9RB
Some results last night from europe.
Brendan1
02-04-2007, 03:49
The morning broadcast shows definite signs of variable propagation, while the afternoon shows a leveling-out of the band conditions. Plenty of non-reception periods to go around. :(
Brendan1
04-04-2007, 02:09
My bad: the operator somehow messed DRMLogger yesterday, so no logs. :eek:
Much better today...although there are a lot of little blips in the data. :confused:
Brendan1
05-04-2007, 02:33
A slow start again, but otherwise fairly steady this afternoon.
Brendan1
06-04-2007, 02:02
Same story as yesterday: somewhat disturbed at first, then leveling off at a good level.
Brendan1
07-04-2007, 02:01
A good, fairly steady day today, with the usual ups/downs in the frames decoded.
Brendan1
08-04-2007, 02:59
Morning and afternoon logs today. AM was fairly bad, PM was fairly good. Go figure... :confused:
Brendan1
09-04-2007, 01:03
The morning was bad again, while the afternoon took a little while to straighten out.
Brendan1
10-04-2007, 02:09
Quite a good log today, with the usual slow start. :)
Brendan1
11-04-2007, 02:22
Nice and steady: that's Sackville right now. Most days of late the broadcast has been very consistent with only some fairly small errors in the overall quality.
Brendan1
12-04-2007, 02:50
Same as yesterday: very good!
A typical day's reception here in the "target area." :(
31 meters dies as the sunset approaches Sackville and reception goes rapidly downhill after 20:00UTC.
Ironic that the target is "NE USA"
73

Rich, it's feast or famine with 9800. 49 meters wouldn't make it to the West Coast, and pretty much anything else would go too far. Despite the "NE USA" target, they're trying to cover all of NA.
A pretty good log for the afternoon, not much to subtract from the overall quality today.

Agreed- it's tough if you're only going to use one freq.
I'd be interested to see RCI do some tests on 41 and 49 meters--- according to their schedule they're beaming to Europe from 20-2100 in AM on 5850 and 7235... they could try DRM modulation and see what the USA hears off the back of the array at 2100 for half an hour or something. 7235 would probably not work for me either, between skip-over and amateur QRM.
If CBC and their clients actually want to have people LISTEN via DRM, they probably should find a way to get a signal reliably to the densely populated Northeast.
Cheers
Rich

Some propagation issues today, with very obvious up/down fluctuations to the log.
