If it is a high-Z output directly from the plate of the tube through a
parallel tuned circuit, like the stock T-368 unit or commercial ham VFO's
like the VF-1 or Johnson 122, I would say maybe 5-6 feet at most, because
the capacitance of the coax running to the transmitter begins to swamp out
So my question to the group. Who is the Collins 20v-2 guru and how much
will
be involved to move it from 610khz to 1885khz.

Why be content to operate on just ONE frequency?
It is very easy to convert those xtal oscillator stages to function as
buffer stages for an external

I'm not Don but I have some thoughts: It depends a lot on the output
impedance of the VFO, I'd think. If it is low-Z, say less than 100
ohms, then I'd think you could run coax quite

Don, I'd be curious to hear your thoughts on maximum connection
distance electrically for a VFO. Barry used to run a VFO on the 300G
and included a short cable with it for that purpose. I know someone
(maybe Paul, VJB?) actually removed the lower window in the door and
stuck the same T-368
Not bad shape at all Al! Not nearly as dirty as I though it might
have been from your description. Congrats on saving one of the great
old AM broadcast Tx's out there. Sad to hear about the demise of the
old AM station however.
73 good luck!

I left the house at 6AM this morning and drove 200 miles to Winchester,
Virginia to retrieve the Collins 20V-2 that was given to me. The station
went QRT Monday and yesterday all 4 320' towers were dropped by cutting a
