[R-390] A Few Questions

[Ed G]

Hello,

     I have been restoring a Capehart R-390A.it was in pretty good shape,
and I have done the recommended cap substitutes, cleaned up the gears, put
the spring back on the Oldham coupler (surprisingly enough I found the
spring still floating under the chassis). No further alignment has been done
yet, but it sounds like a very sensitive receiver.

     Some initial observations and questions for the group:  I notice on
strong and even moderate CW signals that I am hearing both sides of the
signal as I tune, even with BFO knob set to what I think is proper position.
Is this a BFO alignment problem or normal 390 behavior?

     I find I much prefer the WIDE audio response setting even for CW; the
narrow setting seems much too sharp and attenuates signals too much.  Again
- alignment problem or normal 390 operation?

     

Thanks for info.
