[Lowfer] WM in EN90xn

[N8OOU]

Mike, Ok on the short, light overnite traces. Back in early Jan the 
signal to your location was fairly light also. My main effort right now 
is to get the beacon working at the same potential as then.

On the light hearted side;
If you could luck into some brass screen wire from an old-timey lumber 
yard you could make a Faraday cage to enclose everything.  That should 
reduce the background noise.
