The new frequency from Flevo is performing much better here in Belgium than the previous 9815 kHz.

Reception is not yet 100% but I assume some smaller modifications are possible.

We are really pleased with this new choice of frequency, because it should be an improvement for the TDPradio broadcast on Saturdays!

Also in the second hour, reception is quite reliable.

During the third hour, reception is still quite acceptable, but not perfect yet with 88% decoded audio.

Ludo

31-10-2004, 14:00
In the fourth hour, there are more dropouts then in previous hours, but overall still much better than the old 9815 kHz.

By the way, the announcement of the language in the text message was wrong, stating German instead of English in the last half hour.

The reception quality of the fifth hour was again less than the previous hour for the programming of RCI and Radio Netherlands. Only 66% correctly decoded audio.

During the last quarter (from 1500-1515 UTC) the signal further decreased in strength for the German program of Vatican Radio.

Hi all,

the new frequency makes reception of the Flevo DRM Bouquet possible in Frankfurt. Quite good reception and good sound quality.

Hi all,
about 90% decoded audio during the 5th hour, as always lower audio levels than any other station, see attachment
@Ludo: It was not RCI programming (I was not home but I just listened to my recording) as it had been announced but again CBC :( , I hope this was just a mistake today or they could not make the changes in time and we will hear RCI in the future on this transmission.

Hi Simone,

It was indeed CBC (the announcement in the beginning mentioned CBC), but we did not make the distinction between CBC and RCI, they are in the same house, so to say.

The new frequency from Flevo is not as good as 9815 kHz here in Poland.
At least today (it is my first reception on the new frequency).
Today from 13:55 till 14:55UTC, audio was 91% whilst it was usually 100% for 9815 kHz.

Hi,

here is a comparison report using the penultimate and the ultimate CVS-version of Dream with "Mod. Metric" activated on the latter.

This feature is supposed to improve decoding in the presence of interference.

Quite a good result with slightly better percentage of properly decoded audio with "Mod. Metric" activated.

The SNR plots are exactly above each other, so only one can be seen.

Hi Simone, all,

Thanks for this comment. Good to hear that this new UEP settings don't seem to make things worse although I also wonder if the spring conditions have an effect on the target area.

Hi Carsten,
I think we have to accept that we are not in the main target area with this configuration. But the UEP settings they are currently using are quite interesting, allowing good listening with a high bitrate at a relatively low SNR (whenever we get a signal ;))

Hi John

Thanks for this report.

Interesting to see that the adjacent channel station is so strong in Greece. For a more realistic prediction of the DRM coverage I need to include this AM-station within the calculations to get an S/I plot.

09-11-2005, 16:18
Hi all,

Actually there are three (?) interfering carriers.

@ Peter: On 7235 kHz until 15H00 is VOA at a level 5-15 dB over DRM, on 7245 kHz before and after 15H00 there are two carriers with Arabic (?) language at 0-10 dB level over DRM. I suspect that in the middle of DRM spectrum there is a third one hidden and sometimes it appears about 5 dB over DRM. All these make the reception really problematic, although the signal is quite strong.
See the attached file.

John.


PS:Now at 16H25 there is a carrier on 7245 kHz which is more than 20 dB over DRM.

Hi all,

With a signal below 35 dBuV at the antenna input I got the attached good result. Check the similarity of SNR and CDA graphs.

Hello,

perfect!. The TX seems to limit the SNR to 25 dB.

Hi all,

Regarding the log in post #150.
How can be explained that max SNR=25.7 dB, average SNR=26.0 dB and the SNR rms error=0 ? Is it a DRMCalc calculation error ? Is it because a 3 mins only log ?

@Carsten what is your opinion ?

The signal from Flevo on this frequency here is always strong ,
between S 9+20 to 40db
Only Co-Channel AM-Station produce errors. :mad:

As always not reliable here, but better than the past weeks when I hardly got any decoding.

Usually my home location is within the dead zone of that station.

Started quite good in the first hour of my log, later some dropouts during thunderstorms, co- channel AM interferer started at 1300 when I stopped the log.

Here too close in the dead zone of the first hop with backscatter, weird pulse shape and delay.
