RRI on 6040 kHz in B-19

Hi All,

Great the hear Radio Romania's English Service on 6040 kHz at 2300 UTC this evening, it had been missing all week.

As with the 2100 and 2130 transmissions on 6030 kHz, this one shows it's coming from the Galbeni TX1 transmitter and is 20.96kbps in Mono.

A very good signal here at around 21.0db SNR.

A good signal again tonight, around the same strength as the previous day.

I listened 2300 - 0000 UTC this evening (Thursday 7 Nov 2019) to the 6040 kHz DRM b/c from Galbeni. It's the first time in, I think, months that I've been able to decode anything from RRI. It improved through the hour but for the first half hour it was well below 50% audio (MER 6 - 17 dB or so). In the second half hour it gradually improved until by the end of the hour I was decoding about 75 - 80% audio, with MER rates 12 - 20 dB.

Morphy-Richards 27024 + 8m wire aerial. Downtown St John's, Newfoundland.

RRI 6040 kHz Reception near Atlanta, Georgia, USA

Nice strong signal this evening. Was resetting automatic logger and caught only the last 12 minutes of the transmission.

RRI 6040 kHz Signal Coverage

The attachment shows the VOAAREA predicted signal coverage of the RRI transmission on 6040 kHz at 2300z in November 2019 (assuming a 6ft vertical whip receive antenna).

Audio decoding, unfortunately, is not based on signal strength alone. The doppler rate and delay play a big part too. As does the encoding quality of the transmitted signal.
