Support other time signals in radio clock channel #1596

Open kord1e opened 1 year ago

kord1e commented 1 year ago

There are other time signals that are not supported by SDRAngel:

RBU (Russia), 66.67 kHz, strong in some parts of Europe

RWM (Russia), several shortwave frequencies (not sure if this provides the actual clock time or just something less)

Chinese and Japanese signals, may be weak in Europe/USA

RWM doesn't transmit the time of day.

For support of these (other than BBC), we'd need some IQ .wav files uploaded with several minutes worth of the signals.

I can record RBU and also RWM if needed but that's less exciting.

Here's a recording of RBU, 12 minutes, started around 20:29 UTC. not exactly centered but close.

There's actually a lot of EMI, if this is not good enough Ican try to shutdown some electrical devices to see if I get a better recording... but RBU should not be blocked by any unwanted signal here.

Thanks. Certainly cleaner than I can receive. Looks a bit different to the other signals, so may require some thought :)

Have just added JJY. KiwiSDR's are quite useful!
