[600MRG] Not quite there

[Brian Pease]

XKA got WSPR decodes of me on 3 freqs 60.0Hz apart.  Apparently I have a 
weak 60Hz modulation in my 100W Class-E amp.  While investigating that 
(it was not the power supplies), I found that the ringing at the MOSFET 
gates was causing a weak output on ~25MHz. And then there was the 
~1.6MHz gate drive oscillation that occurred when the U3 was not 
transmitting.  At least this last did not radiate!  I fixed the last 
problem, and will try some gate series resistors for the ringing.  Maybe 
I will be on the air in a day or 
two...................................................  At least the U3 
appears to not be at fault.
