*Hello Guys,*
*                    Wow, I just tried to get out of the shack to refill my
coffee and my head wouldn't fit through the door. Thanks for the good
words. Al, I am guessing that just sending the Regulator Board to me for
the Re-Cap job on it for the Omni 7 worked out well? How did the repair we
did for your neighbor work out? And as for Ron, we are so glad that the
Argonaut worked out so well. The biggest problem was finding the Germanium
Transistors. Bob/K4TAX, since retiring has been sending me recommendations
that are getting me about a radio or 2 a week now. And while I am breaking
several forum rules .... A great thanks to Jim Allen, out there. We have
another fellow on the hook and looking into purchasing the opt 3 Omni 6.
You guys have all been Great to work with......*
