Richard,
I performed an electrical restoration on an SP-600 (JX-26)
last summer. The frequency accuracy was poor....WWV at
10 MHz was at 10.2 MHz (approx). What is worse IMO is the
tracking across the bands. The frequency at one end would
be high,
but at the other extreme, it'd be low.

I'm sure this can be tuned out. I just haven't tried yet.

I'm in the process of bring back another JX-26 now, so if
you have any specific questions, you can write me off
list.

Burried in the TM 11-851 handbook (p.35 I think) and in
some Hammarlund advertising, I found a spec of 0.25% for
dial accuracy. This isn't too bad for a conventional
receiver. Also, I suspect the thing is capable of much
better adjustment than this. My experiments will have to
await getting over a back problem.
