Voice of Nigeria - no modulation

No modulation again! or would be modulating with the new codec "xHeAAC"?
I imagine that my DREAM "2.1.1-win32-svn808-df" is not able to decode "xHeAAC".

Judging by the poor audio techniques utilized before, I don't think they have gone to the other extreme with a new codec.

This afternoon's reception - 59.16% (silent) audio decoded, 14.42 dB max SNR.

A weak RF signal, below 40 dBuV plus fading, gave a result at 93.5 % CDA. Decoding even at 30 dBuV! RRI take a notice of this...

Yes, indeed, shortwave broadcasters take note of switching to more robust modes.

I autologged this frequency last night but no trace at all of a signal in Japan.

The label says: You are listening to a DRM test radio from Voice of Nigeria, Abuja, but there is nothing to listening to. Weak signal, best results near the last 10 mins of the log.

Hi T.P.,

See my posts 31, 59, 60, 61, 85, 94, 97, 98 and 109. Later the same Mr. Abd......m sent me a scam e-mail regarding moving ump-teen million USD with the usual conditions, so I stopped writing to him.
