[Skimmertalk] Red Pitaya set up with N6TV's instructions

[N4ZR]

We're with you 100 percent, Wes. I have just finished evaluating an RP 
with the input transformer (actually home-brew but the same 14:1 
transformer) and see virtually identical performance to that of the 
QS1R. My test unit, with the plastic case and a 25mm cooling fan, never 
exceeds 58C.  I feel no trepidation about saying we'll use the RP in the 
gap-filling program, with plastic case and cooling fanas Wes suggests.

In fact, the one I'm testing here will probably go to the next 
gap-filling location.  We're still looking for a site in West Africa.
