[Lowfer] WM and SIW this AM~PM

[N8OOU]

Mike - tts;

Are you still able to copy the modified WM id after the 19:00 utc 
restart? Raising the frequency did slightly drop the PA Input power from 
.99W to .96W.  After going back and checking the antenna tuning it 
seemed to be in resonance.

Thanks for the reports.
