Good reception here tonight.
A real highspeed oscillator and the same strange snr rise at start of transmission.
No more resyncs here, found the problem.
The F5k is OK, some soundcard drivers are really bad!

Thumbs up CVC DRM to Brazil in 31.08.10

Em 31.08.10 houve o maior número de rádios DRM direcionadas ao Brasil em apenas um único dia: DW, RNW, TDF, TDP, CVC. Foi também o maior número emissões que eu consegui decodificar o áudio aqui no sul do Brasil, cidade de São José, Santa Catarina.
Parabéns e meu "Muito Obrigado" à todas as pessoas que fazem parte direta ou indiretamente ao DRM no mundo.

On 31.08.10 there was the greatest number of DRM radios directed to Brazil in a single day: : DW, RNW, TDF, TDP, CVC. It was also the largest issues that I managed to decode the audio here in southern Brazil, São José, Santa Catarina.
Congratulations and my "Thank You" to all persons belonging directly or indirectly to the DRM in the world.

Hello,

one sync-loss. I had to push "NEW DRM aquisition" to start decoding again.

Many parameters in a short time, difficult to report with small attachments.
With anything below 17 kbps you will lose at least one listener.
It does not need DRM for transmitting music at telephone audio quality.

Interesting log. It's a pity I had not switched on the auto-plot with the automatic screen-dump function. If I had, then I would have known what all these different modes were. There were 7 different modes in the list.

@Mathias: OK, understood.

Hi Stef, must have been a local problem. Good signal tonight, also one dip here.
Attached are two panadapter screenshots at the same signalstrength with low and high intermodulation giving 24 dB and 16 dB SNR.
