[600MRG] WH2XHY now beaconing WSPR on 475.720 kHz

[sbjohnston at aol.com]

 I got a report that VE3OT was already on 475.0 in QRSS6 slow CW mode, so I shut down my CW beacon for now.  

I was getting 2 amps into the short antenna on CW and maritime transmitter seemed stable.  Heat sink was getting warmer than I recall when antenna had the top loading wire.

I'm now running a WSPR beacon on 475.720 kHz. The "carrier-current" amp wants to oscillate on short antenna but I'm trying to keep it stable.  With driver gain reduced to stop oscillation I'm making about 0.5 amps into the short antenna .
