Ok, so looking at the RF-IN (Resonate Input - where it resonates best at - in rest) the Nano - gave you your answer just the window you saw this in, was too narrow.

So, in your radio - it uses a "Doubler" or even Tripler to obtain the frequency. Was not sure if you have two radios using CH14 or you had two from the Same unit.

The Doubler with another Xtal of slightly different Resonate frequency - when one was "doubled and summed" produce 27MHz but if you swap the Doubler to use the other Crystal and then sum it with the other - is another method.

Oh, it just Bums me out I don't have my old TRC-200...busted antenna - removed the "Dummy batteries" so we could eek out a few more mW of power...

We used to get the Xtals for these thru Radio Shack and had to be one of the pairs of Xtals one was tagged in Red, the other Black or Blue - installed this way - to this socket, the other went to this socket, if you didn't get it right - you didn't have CB channels - but you did get instant oddballs.

Boy those were fun days.
