[R-390] CL80....

[Jerry Kincade]

Sounds like some RF tweaking is in order, per the good 'ol manual alignment
procedure. 10KC is WAY too much for one of these, my 600 is not off more
than 1 KC anywhere in the BC band, and is very close to dead on most of the
way. Noticeable drift is essentially non-existent, too. That's not a "nyaah,
nyaaah", it's just proof these things are capable of much better tuning
accuracy than you are experiencing. This one is a JX-17 w/factory ceramics,
totally virgin, untouched and un-aligned from day one as best I can tell.
Likely yours was "aligned" by a previous ham owner with a wandering
screwdriver and no non-magnetic alignment tools. :-) I'll bet you can get it
MUCH closer than that without too much trouble, as long as it's been
recapped or has factory ceramics.
