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 30H
It will soon be crowded on 137kHz WSPR - great! 73s Roger G3XBM On 18 September 2010 16:32, Andy Talbot <[email protected]> wrote: I lied..... The sequence repeats every 64 minutes Andy www.g
