[Lowfer] Watering Hole

[N8OOU]

Mike,
I see how having a close in transmitter impacts receive capability even 
when operating "bands" apart. With both WM transmitters located on the 
same property, I have impacts on receiving. I am confident the 
transmitters are clean, they just overload the receiver.

You are correct with the "power" observation on the "WM" graphics. It is 
there by design.  I saw in early dummy load testing that I could use it 
as a received signal strength indicator. For the moment, the slant lines 
are coded with 2 levels of "ARGO" power. I think it can be upped to a 3 
or 4 level indicator. I'm working on that change now. For now I have 
been watching the real world results to see if the 2 step idea is workable.

Thanks for the observation and interpretation of the beacon signal.
