I left the SDR on this freq while out doing errands. Around 1802z a very weak abrupt increase (~2dB) was noted in the noise floor in the Strength History, and I also note a weak carrier now in the waterfall around 1825z. No audio, but will keep an eye on this. I need to re-calibrate the SDR freq, but appears almost nominally on 15476.
Faded out or off around 2000z, so absolutely nothing definitive here.
