O sinal 17.545 Khz da TDF chegou ao sul do Brasil, mas não decodificou o audio.
Os 21.520 Khz nos primeiros 25 minutos também está chegando aqui no sul com maior intensidade de sinal e já teve pequenas decodificações de audio. Deixarei gravando o log até as 21:00 hs :p

Only one log worth posting, the 17545 from 2100-2300.

First transmission, 17545kHz 1400-1600: only some extremely weak signal peaks between 1452 and 1455, max SNR 2.6dB.

Second transmission, 21620kHz 1600-2100: nothing at all.

Third transmission, 17545kHz again, 2100-2300: signals for the entire period, although audio decoding only began after 2220, max SNR 19.7dB.

Fourth and last transmission, 15525kHz 2300-0050: nothing at all.

Not bad here on 15m tonight:

Okay, so I've got three logs tonight. In my humble opinion, 17545 was the best all around frequency for this test.

Nothing recorded on 21620 today, not one little electron. :(

Very marginal this afternoon.

My thanks to Michel, Jacques, and the Montsinery crew for running the tests to both Las Vegas and Mexico City. It is so nice to have some variety in DRM programming here in the Americas, even if only for a short time!
