[GreenKeys] Chirppie FSK

[Larry Tighe]

Howdy RTTYer's,

I finally fixed the Dovetron AFSK...or should I say, I did it correctly?

I am using a stripped down ESU...polar relay and PS...in series with my 
loop.  The polar relay is now rewired to use just the contacts...floating. 
I have two 9 volt batteries whose polarity is switched to the polar input to 
the AFSK Dovetron oscillator.

By the reversing of the 9 VDC, manufactured polar, the AFSK works perfectly. 
I put a pad on the output to adjust the level into my Sunair xmtr.  I should 
have her up on 80 meters sometime tonite using the refurbed Model 28ASR with 
the aux typing reperf.

Last step is to re-install the cooling fan for the fins of the Sunair 
exciter's final....it'll be driving the Sunair 1 KW PA.  Gotta cut a CQ tape 
too.

Watch for smoke by facing NJ :>)
