A test transmission from Voice Of Nigeria. Low bitrate but fairly good sound when they played music but terrible when they started talking. Riyadh killed the fun just before 12 UTC.

I clicked the checkbox to log the reception, however, DREAM did not write anything usefull for the plotter into the files.
At least it recorded this: SNR min: 3.1, max: 19.7 (I guess the max. was at about 1440 UTC when I stopped the log)

My log resembles Sixten's very much in regard to the Doppler values. A few drop-outs might have been due to the use of electric machinery in the house. The transmission ended suddenly at 0920 UTC.

I think that the audio was pretty good despite the low bitrate. The levels were perfect and the vocals sounded rather good even though the audio bandwidth was limited to 3000 Hz.

(Thanks Simone for fixing the headline)

An unattended log from this afternoon. Severe co-channel QRM from a 500 kW AM TX in Saudi-Arabia. By the way, Voice Of Nigeria is not scheduled for this time of the day on 15120 kHz.

Nearly perfect reception this morning. Nice text message: "Test with THOMSON transmitter TSW2300D. 125 kW, fixed curtain antenna to North. Greeting from Abuja, Nigeria."

Is this only a temporary test, or will they continue until I arrive back in Switzerland around the 25th March? :confused:

@Simone: Thanks, dunno what happened there... Five views down the drain - hihi :o OK, the whole window must be on the desktop... I see...

Not as good over here.
@ Digger: Can you please check your attachment. As far as I know it is only a test transmission for now.

Almost perfect reception except towards the end in this mostly unattended log. I heard the start and listened for an hour or so, then I had to leave. The Doppler was fairly high at times, the SNR dipped suddenly around 0835 UTC but around 0912 it rose again suddenly. Perhaps this was caused by splatter from an adjacent channel. SNR peaked at 24 dB on my Roadstar, which never produces much higher values.
