Generally with PTO radios of the tentec and Drake realm if the PTO is drifting something
isn't right.? I start there.? ?
Exceptions are Swan and Atlas plus a few older Tentec like the Argonaut 505 and 509 as?
they use a fairly high frequency PTO for some bands.? It doesn't solve the problem of
dial calibration or drifting for narrow modes like JT8 or even PSK31.
Rather than going the huff&puff I just drop in a DDS or 5351 and kill the problem cold.
The only one I've resorted to for that is one junker level Atlas 210 and that vfo was
not savable due to 11M mods the rig was subjected to.
