Good signal here at the moment 1500 UTC on 6105 kHz, but no sign (not surprisingly) of the 15300 kHz transmission. Male in French and a female with French accent, but reading weather info in English at the moment.

The broadcast is showing TDF DRMcast and is in the usual 15.62kbps.

1500-1600 on 6105 ISS 100 kW / 255 deg to NWAf French MiniTrans DRM

Here was an sufficient signal to receive. SNR Max:22.4dB
The spoken weather infos was strong overdriven.
The reference receiving with the Uniwave was unbearable with this overdriven voices.

What DRM receivers are they using on the yachts?

According to VOACAP (see attachment) not much of a chance to decode anything at my location, but the sea-going participants should have good 15.3 MHz signal levels along their route.

The corrected plot is shown in message #17.

What time 15300 was broadcasting? Probably strong signal here in Brazil.

TDF DRMCast 15300 kHz DRM, 10 OCT 19.

Amazing signal in extreme south of Brazil. I know the Brazilian Carlos Accari from TDF DRM tests: https://photos.app.goo.gl/TaSdKcBnn6GmmhSe8

Oct_11 - TDF on 15300 kHz

I got this transmission with a lot of fading. Distorted audio due to overmodulation, 26dB max SNR.
