BBC & DW on 9545 kHz from Woofferton

[mitajohn]

Hi all,

A log for almost the whole transmission. The signal was stable ~40 dBuV and not affected too much by the QRM. After 11:00 I decided to log in parallel with DRMSWR and make afterwards a comparison. The SNR was always a bit higher with DRMSWR but the decoding was more problematic.

[Digger]

One hour from this morning. Perfect results here.

[Sixten]

Her is part 1 also from start . CRI have not start but hi delay.
First log from 9545. Good signal but also strong Signal from CRI on 9540 .
CRI stop 1425UTC and DRM bee better. Log last 100min.

[simone]

Some periods with a weak signal today.
Simone

[Brendan1]

Just to get in on the fun - I had the slightest little signal on the waterfall just before closing today, 1458-1500. Not even enough to get 1dB of SNR, just a noticeable pattern with polar path propagation. I'll just have to try harder! ;)

[mitajohn]

Hi all,

I started the log late, using both SWRs.

1st file: With the presence of QRM on 9540 kHz Dream got better decoding results but lower SNR. About 5 mins before the end a strong carrier appeared on 9550 kHz killing DRM.
2nd file: The FhG SW cannot display the Journaline content.

[Sixten]

Hi all.
Yes mitajohn on 9540 is Cina Radio International very strong, if DRM fading down CRI brake DRM signal. Log today 64min.

[simone]

Good results at 1130- 1400, an unstable signal for the rest of the transmission.
Simone

[Brendan1]

Greetings everyone!

Here's a screenshot of what I was able to copy this morning just before the broadcast closed. No banner name, but it was them, about ~1dB SNR.

[mitajohn]

Hi all,

Here,s the results for a two hour log.

[Sixten]

Her is 102min. log ,CRI up 20db over DRM 1238. But also propagtion go down.

[mitajohn]

Hi all,

Here's a 4 hour result, almost perfect, except of some dropouts near start up TX related.

[simone]

Rather good results until 1400, a much weaker signal then.
Simone

[drmdab]

Good reception results. EPG, AFS and Journaline worked fine using DREAM.
Audio quality was not that good.

[Sixten]

Perfect signal today. :) :)

Last 51min log.

[mitajohn]

Hi all,

A result for 4 h 15mins with both SWs.

[simone]

Signal got weaker from 1345, good results until then (4* MDI problem noticed around 1300).
Simone

[Digger]

An unattended log. 98% CDA up until 1435. After that nothing. I was listening upstairs to 9545 kHz but did not notice any problems; probably the Morphy decided to switch automatically to 15 MHz instead.

[Digger]

Very stable reception on this frequency. Only one major problem: The audio disappeared for a minute or so, but the WOF TX did not shut down (the SIN audio AND the carrier disappeared for a short while at the same time).

[mitajohn]

Hi all,

In the presence of QRM always some decoding problems but overall SQ > 99%.

[mitajohn]

Hi all,

An unattended log today.

[Brendan1]

A very short log from the western US. Best reception yet. Journaline was showing as a second channel on Dream, but no data was received. EPG was available and loaded; first time I've ever received one and it worked as it should.

The waterfall showed quite a bit of polar flutter to the waveform, but it reached a maximum of 7dB in those seven minutes.

I'll try again tomorrow for a longer period. I just have to climb out of bed earlier. :rolleyes:

[Digger]

Hi Brendan and all,

My turn to welcome you to this side of the puddle, Brendan. ;)

Here is a two and a half hours almost perfect log with a couple of dropouts that I cannot explain.

[mitajohn]

Hi all,

A mostly unattended log.

[Brendan1]

Hi Terje and all,

Thanks for the welcome! I arose just before 1400 today and started logging right away. From what I observed and logged, it would appear that I'm benefiting from grayline propagation just before local dawn. At the start of the log there was nothing visible on the waterfall, but by closure it was very obviously there.

Not as good today, the A index is up to 6 right now. Didn't even get the SDC to read out.

[Woofferton]

Hi All, The content server in London had a config issue this mroning so we were off between 10:45-11:04.

[Digger]

Yes, the break was noted. Another short TX failure seems to have occurred between 1117-1119 UTC? There were some more problems where the SNR dips can be seen. Just after 14 UTC the signal became rather weak for about ten minutes, it recovered quickly.

[mitajohn]

Hi all,

A ~5 hour result with SQ >99%.

[simone]

Excellent today, probably my best results since the start of this transmission.
Simone

[Digger]

Perfect reception, Doppler was a bit high at times.

[mitajohn]

Hi all,

Perfect results for 4h43mins, except of the strong QRM period when DRM decoding spoiled, both SWs.

[Digger]

The propagation nose-dived around 1255 UTC. I stopped the log 20 minutes later as there was no improvement.

[mitajohn]

Hi all,

Here's a result for one hour. One major dropout.

[Digger]

An unattended log with various results.

[Sixten]

Very bad propagtion up and down from start and so 1400 start Radio Slovakia on 9540 30db over DRM . 9540 close down 1430 and now propation go very fast up - And signal stringth was 64dbuV 1500UTC . Log start 1332.

[mitajohn]

Hi all,

Although the signal was always below 45 dBuV it was stable and I got a perfect result for 4 hours.

[Digger]

Between 10 and 13 the result was perfect here too except for a short period around 11. After 13 UT everything went haywire so I stopped the log.

[simone]

Poor conditions on transmissions from Woofferton today :(
Simone

[mitajohn]

Hi all,

An unattended log for more than 3 hours.

[Digger]

An unattended log for the whole transmission. About 90% CDA.

[mitajohn]

Hi all,

A mostly unattended log for about 4 hours (Both SWs) with nearly perfect results.

[Sixten]

Hi all.

Bad propagatio her also. Log 105min CDA 92%ok.

[Sixten]

Hi all.

Her is 100min log today , but signals from Wofferton have always very Hi delay her in Sweden so this gve dropouts . :confused: :confused:

[Brendan1]

Well, Simone found out something: I could not have been receiving the EPG as it wasn't being sent that day!

She sent me an example of what an EPG should be, and what I found was that I had been looking at the Live Schedule screen, not the EPG.

I apologize for the error, as we don't get either an EPG or Live Schedule data out here at all, and I had never seen either one before.

Live and learn. :rolleyes:

[simone]

Good results until 1250, problems with AM interference later.
Simone

[mitajohn]

Hi all,

A mostly unattended log, both SWs.

[Digger]

A mostly unattended log. One weak period around 1430.

[simone]

Only a short log today, good results.
Simone

[Sixten]

Hi all.

Good signal stringth but bad DRM progation from Wofferton and CRI strong on 9540 and 9550 :eek: :eek:

[simone]

Good results except the last half hour with a slightly weaker signal.
Simone

[mitajohn]

Hi all,

An unattended log. Some periods with decoding problems.

[Digger]

Almost perfect for 54 minutes during the last hour.

[mitajohn]

Hi all,

A 4h27mins log. Decoding problems when QRM got stronger (log with both SWs).

[mitajohn]

Hi all,

Almost the whole transmission. Decoding problems, as most of the time, during strong QRM, which deteriorates the SNR spectrum.

[Sixten]

Hi all.

Strong signal stringth but bad DRM propagtion every day this time from Woofferton to Sweden ?????:confused: :confused:

[simone]

No problems here, almost perfect results all day.
Simone

[mitajohn]

Hi all,

A 5 hour log with both SWs.The signal today was stable 40-55 dBuV. There were decoding problems during the QRM period, which is obvious in the graphs.

[simone]

Good results except the last hour.
Simone

[mitajohn]

Hi all,

A result for an hour.

[FritzWue]

Goettingen-A7-Kassel-A44-Wuennenberg-Haaren
Strong fading plus some noise from the car on 31m:

[mitajohn]

Hi all,

Except of the TX related dropouts the rest was perfect.

[Digger]

After 14 UTC there is too much AM splatter from 5 kHz down. Unfortunately, this kills the DRM transmission completely.

[Sixten]

Hi all.

Good signal today from Wofferton . Log first 1h. :)
Signal stringth strong last h. but bad propagation from 1300to 1400 UTC. Log part 2.

[Sixten]

Hi all.

why is propagtion so instable every day from Wofferton , not probem for signal srtingth. 54/64 dbuV .:confused: :confused: :confused:

[Sixten]

Hi all.

Log today is compare with log from Jan.23. 60min from Wofferton.

[Digger]

The last 48 minutes from Woofferton today. Almost perfect.

[simone]

Poor results today, especially in the second half.
Simone

[Sixten]

Hi all.

Long log today 204min. Good signal in start, but not good propagtion and 1230 UTC start CRI on 9540 S9+30db .

[Sixten]

Hi all.

Propagtion better today . :)

[FritzWue]

Freiburg-A5-A98-Rheinfelen
Dips at gas stop and in a tunnel.

[Digger]

A good log from 12:30 and on. The signal disappeared around 14:30.

[simone]

Good results only for two hours today.
Simone

[mitajohn]

Hi all,

Problems due to QRM but also 30 mins of perfect results.

[mitajohn]

Hi all,

Problems due to QRM but also 30 mins of nearly perfect results, similar to my previous post.

[simone]

Quite good until 12:20, then signal got weak er and unstable.
Simone

[Sixten]

Hi all.

Good signal first 2h. to CRI peak 20db over DRM in fading. :eek:

[mitajohn]

Hi all,

An unattended result for 2 1/2 hours (both SWs).

[Digger]

The three flaws in the log correspond exactly to the ones in John's log.

[Sixten]

Hi all.

Very good signal stringth first h. but instabile DRM propagtion , 1200 start CRI on 9540 and problem was big for dropout. CRI come over DRM in fading, last 60min. in log. Log is 3h. 46min.

[mitajohn]

Hi all,

A lot of TX related major dropouts and some minor due to the known QRM.

[Digger]

100% perfect reception for 1 h 19 min.

[Digger]

Almost three and a half hours of near perfect reception.

[simone]

Good results except 1230- 1300.
Simone

[simone]

Good results today.
Simone

[simone]

A weaker period from 1315- 1430, dips before 1300 were probably MDI feed related (same from Sines).
Simone

[mitajohn]

Hi all,

A perfect result for 2 hours.

[Digger]

Much better than this is almost not possible.

[simone]

Excellent results yesterday, not so good in the last half hour today.
Simone

[simone]

Quite good results until 1300, apart from MDI feed problems.
Simone

[Per]

Hi,

Unfortunately no good reception from Woofferton at my QTH. Or is it me that is spoiled by the always perfect reception from Sines?
Time: 10:10-11:11 UTC, which resulted in a CDA of just 20 %.

[Digger]

At least the three comments I wrote in the log were TX failures. No RF signal at all. The earlier breaks I did not notice, or I was not near the receiver. Otherwise perfect reception.

[mitajohn]

Hi all,

An unattended log. A lot of deep dropouts...TX related ?

[simone]

Again MDI feed problems today, a weaker signal from 1400.
Simone

[Digger]

The first 1 1/2 hours were OK, after that some problems with the audio

[simone]

Good conditions until 1300 (but the known problems), a weaker signal later today.
Simone

[simone]

Good results except the last half hour with a weaker signal.
Simone

[dsp4swls]

new SoDiRa Logging functionality

[Sixten]

Hi all.


Propagtion not so good from Wofferton. Log 2h.

[Digger]

Perfect except for the last 35 minutes.

[mitajohn]

Hi all,

Good reception but decoding problems due to the QRM.

[simone]

Perfect results until 1330.
Simone

[simone]

Great results until 1400 today.
Simone

[simone]

Not sure what happened in the first half hour, quite good then until 1400.
Simone

[simone]

Quite good results today.
Simone

[mitajohn]

Hi all,

Problematic result although the signal was good and QRM problems. Notice that the SNR is not affected that much by the sharp drops between 12:40 & 13:15 in DRMSWR as in Dream.

[Digger]

There were four TX failures during this 3 hours long log. No signal.

It is pretty exciting to hear (at least twice) during the day that "it is 4 o'clock UTC". At least you jump the first time you hear it, and you think your ears gone bad, but the second time you hear the annoncement a few hours later, it feels real strange... :eek:

[simone]

Great results today.
Simone

[simone]

Almost perfect results again, apart from one dip.
Simone

[simone]

Maybe a problem at Woofferton at 1100- 1130, perfect for the rest of the time.
Simone

[mitajohn]

Hi all,

An almost perfect result for 30 mins. The signal was about 40 dBuV but with rather low SNR.

[simone]

Great results today.
Simone

[FritzWue]

Strange result today.
After 13:00 UTC the the signal was still visible much weaker
and the label was still decodeable until 15:00 UTC.
Dream was running unattended then and finally crashed, so no SNR max. value.

[mitajohn]

Hi all,

A perfect result this evening in-spite of the QRM.

[mitajohn]

Hi all,

Decoding problems during QRM period.

[mitajohn]

Hi all,

A perfect result until 12:00 when a strong carrier appeared on channel (TX related ?) disappearing DRM for a couple of secs and at 12:16 the TX broke down (only the AM carrier was present). DRM came back later but I had already stopped of logging. I noticed that after 12:00 the SNR jumped up by ~5 dB.

[simone]

Also noticed the problem today, no DRM signal for about 10 minutes.

[simone]

Good results today.
Simone

[FritzWue]

Not good today at the dutch border:

[mitajohn]

Hi all,

A perfect result for 4H45 with a bit lower SNR until QRM started and killed DRM.

[Digger]

Not very good in Stockholm either.

[simone]

Quite good results on mobile reception on A3 near Nürnberg/ Würzburg.
Simone

[FritzWue]

At the dutch border good until about 13:30 UTC, strong noisefloor:

[mitajohn]

Hi all,

Mostly the same scenario due to QRM.

[mitajohn]

Hi all,

Much worse this evening.

[Sixten]

Hi all.

Bad propagation from Wofferton .

[mitajohn]

Hi all,

Not bad here, except of the problematic QRM period near the end of log.

[mitajohn]

Hi all,

An unattended result for about 3 hours.

[simone]

Good results at the start of the log, a weaker signal in the last 15 minutes.
Simone

[mitajohn]

Hi all,

A mostly unattended 4 hour log using both SWs. The DRMSWR produces better SNR figures but Dream better decoding results.

[mitajohn]

Hi all,

A rather weak signal today. A more than 3hour log with some decoding problems.

[mitajohn]

Hi all,

A result for more than two hours with both SWs until strong QRM started and killed DRM.

[mitajohn]

Hi all,

A 2H31 result. The log started with a weak signal which got better towards time. A TX break-down noticed at 12:00.

[Brendan1]

A very short log from NA for this one. It only gets decodable when grayline propagation hits the QTH here, otherwise it's very weak (and I'm asleep!). :rolleyes:

[Brendan1]

A two hour log with minimal results for today. I would have to say it's the changing propagation that caused such bad results, as I usually have had ID and some audio before.

[Brendan1]

Almost, today, almost. :rolleyes:

[simone]

Perfect results for almost four hours today using the H101 (CIAO SDR), slightly higher SNR after the break at 1200.
Simone

[Brendan1]

My meager DX log of two hours. I had to point the antenna towards Montsinery before I left for work, so naturally the drop just after 1400 is the result of that. I'm off tomorrow, so I'll do it by hand after I log this in the morning.

[Brendan1]

I need to get up a little earlier, although today it probably would not have made much difference.

[FritzWue]

Unattended log:

[Brendan1]

Just a few minutes today. Here at the home QTH I have quite a bit of co-channel analog interference until the very end, so whatever I can get I truly appreciate.

The same service on 13590 is never as good, and only right now is showing any signs of strength (0900 local).

[Brendan1]

Propagation has been off today, and the short duration of decode shows it.

[simone]

Quite good results for almost four hours today.
Simone

[Brendan1]

Not very good until it was time to go off air. :eek:

[Brendan1]

Not great, but better than most days of late.

[mitajohn]

Hi all,

An almost perfect result for 30 mins, inspite of the QRM.

[Brendan1]

Slowly this one is getting better.

[simone]

Some dropouts at the beginning and a Tx break at 13:37- 13:50.
Simone

[Brendan1]

A little bit today, not much.

[simone]

Some problems at 1433- 1442, pretty good for the rest of the whole transmission today.
Simone

[Brendan1]

Somewhat rough conditions here, but that's "normal." :o

The analog interference here from Asia is pretty bad up until the last hour, and I don't expect that to change any time soon.

[Brendan1]

A few minutes of log today: not the worst day, but not the best either.

[simone]

Great results today, only a few small dropouts in the last five minutes with a weaker signal towards the end.
Simone

[Brendan1]

Only a few minutes again, and not so good at that. :(

[Ant-SWL]

A short view to BBC/DW on 9545 Khz. Very good Signal and result...

[FritzWue]

Osnabruck North-A1-A30-A31-Gescher
Good result, SNR is higher, I still have car e-box interference on 31m:
