By the way, I see suggestions how to just "stretch" crystal controlled
oscillators a bit by adding a suitable coil and capacitor in series with

the
crystal. Has anybody tried that with the AC-1??
Would be nice to be able to get out of the ways of some of the big power
guys.
Any suggestion would be welcome.


An rf choke or variable inductor of between 7 and 20 uH in series with a
variable cap of about 200 pF in series with a crystal, will pull the
frequency. It's called a variable crystal oscillator or VXO. You're probably
using FT-243 crystals, though, and they don't pull very far.

I have to say this again: Time to put this thing on the shelf. For the time
and trouble you are putting into it you could build a solid-state rig that
would put out as much power, have a VFO and not contain life-threatening
voltages.
