Perfect reception!

OBS:
The log "17495-111215-1601-1758-PP5AZF.png" was obtained in another receiving system in the center of the city of Florianopolis in a lot of noise. We used a dipole antenna hastily improvised.

O log "17495-111215-1601-1758-PP5AZF.png" foi obtido em outro sistema de recepção no centro da cidade de Florianópolis num local de muito ruido. Foi utilizada uma antena dipolo improvisada as pressas.

Thumbs up

Decodificação >99% das 16:00 as 17:59h UTC

OBS: A recepção reinicia a cada 18 min aprox. Por este motivo, minha recepção não consegue completar 100% da decodificação.
Na prática, a decodificação foi perfeita, sem cortes durante 2h seguidas..

17495 kHz TDF Montsinery (DRM test to Brazil) reception near Atlanta, Georgia, USA

Today's reception report (1800 - 2000) from the back of the beam - 0.30% audio decoded, 13.10 dB max SNR.

Interestingly the test program, complete with multimedia slides, continued on 17755 kHz at 2000 instead of the scheduled "The Disco Palace"!

Yesterday's reception report (1800 - 2000).
Audio: 95%
SNR: 17dB to 30dB
Some confusion occurred around 19 ​​hours, the audio gone for minutes, back*, gone again, and program information change to "The Disco Palace" no audio, and finally return to test program, *from the beginning.

Thumbs up DREAM 1.10.6 - problem reset every 17 min

Senhores

Entre 18:00 e 18:36h (UTC) eu utilizei o software DREAM versão 1.10.6. Porém, como este software apresentava reiniciação da recepção a cada 17 min, resolvi mudar para o DREAM versão 1.6.2.

Com esta alteração de versão não houveram mais as reiniciações, finalmente.
Entre 18:53 e 19:52h UTC ocorreu 100% para o "Decoded Audio" e para o "FAC CRC". Perfeito!

O SNR esteve muito estável, mais pareceu uma "reta".

Infelizmente eu não havia tentado fazer esta mudança antes e meus LOGs do DREAM nunca chegavam ao 100% como aconteceu hoje, na última 01h hora de transmissão da RFI/TDF/EBC, em 17.495 khz.

************************************************** *****
Gentlemen

Between 18:00 and 18:36 h (UTC) I used the DREAM software version 1.10.6. However, as this software had the reception restart every 17 minutes, I decided to switch to version 1.6.2 DREAM.

With this change in the version there were no more reboots, finally.
Between 18:53 and 19:52h UTC was 100% for "Decoded Audio" and the "FAC CRC." Perfect!

The SNR was very stable, looks more like a "straight".

Unfortunately I had not tried to make this change before, and my DREAM logs never reached the 100% today as it did in the last 01h hours of transmission of RFI / TDF / EBC at 17,495 kHz.

************************************************** *****

Vídeos da recepção de hoje (21.dez.2011):

1) no receptor portátil Morphy Richards:
