Same here using a TCXO. I think my QRG accuracy is about + / - 0.1 Hz on LF also. HI !

Near enough.  Its only a TCXO controlling the frequency, so a ppm or two of error can be expected

Hello Andy G4JNT

 

Good copy. Your SlowCW-30 is on 136173.99 Hz now. Is that correct ?

Hi Andy,

just shifted my Eu-grabber a few Hz up, and Bingo there's your fine signal. Albeit a bit clobbered up by my local transmissions on 137705 Hz.

If you went a few Hz down to below 136175 Hz you'd surely be picked up by several European grabbers (e.g. DK7FC).

Best 73,
Markus (DF6NM)

Having just put the 137kHz system back together, cobbled together an on-off modulator and reprogrammed a beacon keyer module for QRSS...

I [think]  there's a SlowCW-30  signal going out on 136.179kHz,  which is a few Hz above where Mike said he'd be running in the evening.

 

Its so long since I've done this on-off stuff hope I've chosen a suitable frequency.  It can be shifted at a moments notice if requested.
