It will soon be crowded on 137kHz WSPR - great!

To test it out, I've just put a low power WSPR beacon on air.  RF Power into the antenna is about 8 Watts (from a 12V audio amplifier module) so ERP is in the 1mW region.  Frequency 137530Hz - ie 30Hz above Roger's   Duty cycle 33%, and the transmission PN sequence repeats hourly.
 
The callsign is not this one either :-)
