nicely done John
saved a copy to M folder

My one time on the air used the same output final with out the filter
I tuned the antenna/feed to freq with an old NDB variometer. Real 
interesting to see the wave shape change as the thing tuned, Was a good
Square wave 
into a 50 ohm resistive load. Looked like a proper sine wave on freq
and really ugly anywhere else. Filters are necessary to keep folks up
frequency happy
it will be interesting to see how the learning curve goes when activity
starts on 136
I wonder what kind of info QST will have to offer. This band will really
lend itself to
loads of fun and I suspect many surprises
