Today's daytime reception was quite poor, because due to a high local and atmospheric noise level continuous audio decoding wasn't possible more than a few minutes. :(

Now that the AM signal is...

At 23.5 kbps here (near Cologne) the SNR is still 23 dB (upper limit for the WR-G303e).

The sound is better than on 6.095 kHz but female voices are still hissing.
I think this is a good bit rate,...

Hi!

Excellent signal! :)

Even my "Satellit 700" with ferrite rod reaches a constant SNR above 20 dB.

The SNR dropped during the last 40 Minutes so the lower bit rate is helpful.

That's not an easy question. According to the WR-G303 series specifications the important phase noise should be low...

You're absolutely right, Carsten.

I'm curious what mode they will use during daytime. Bit rates of more than 23 kbps should work fine for ground wave propagation.

I'd agree that the sound is a little better than AM but not good enough for the "ordinary" listener.

Signal strength and SNR had been a bit higher one hour ago but still no dropouts so far.

Proper signal strength and SNR, no drop outs yet.

Hi!

Attached are my results of last night: Much better than my experiences two days ago.

Since I was too tired to stay awake I have no idea how the reception "felt" like.

Before I go to bed here are my results of the last minutes (slowly getting better after all).

The signal strength is not as good as expected. So the signal is very sensitive to the local noise...

Hi,

my first test on 1.440 kHz is a bit disappointing: I just get some fragments of audio.

Impulse response looks better here (see attached file) but the average SNR is too low.

There are no such transmissions now and I rather doubt that there'll be some in the future. In most regions...
