[Lowfer] WM and MP post dinner shot

[rick kirby]

Great job Bill! Thats a fine signal down here in the Poconos!
 I just put my new transmitter on last night.I put a 7414 buffer stage in 
it. I was having some drifting problems under long keydowns. I also used a 
series regulator in the supply but I  still want to replace the supply 
someday.
 I used one of the Digi-Key transformers you suggested . I found that I had 
to use 20 turns on the primary to get the final down to 1 watt input at 
resonance.
 Right now its very windy here . Im monitoring my signal using Spectrumlab 
and a downconverter. I see no frequency pulling here BUT  I still notice 
that the final current bounces around a bit on heavy wind gusts. Do you have 
issues with your loops also in the wind or do I still have a problem with 
mine?
