Hi,
A few months ago I bought an Omni-D with power supply from an e-bay seller.
I have been using it, and I enjoy it.
It is exhibiting a constellation of faults which I need to repair.
I would like to run them by the group to see if there is some
common wisdom about them. It may save me some time if I can target
my efforts.
1 - frequency drifting and jumping
This seems to happen on both transmit and receive. Multiple bands.
The amount of drift is about 1-2 kHz. It will usually drift downward
then jump up. This happens when I am not touching any controls.
2 - frequency loss
I have only had this happen on 80 meters. The frequency will jump
much farther and/or the display will go to 1.0000
3 - low output
Output while transmitting will fluctuate.
All of these problems seem to go away if I let the radio warm-up for an
extended period.
My main tuning knob seems to turn easily enough, and all of the other
controls seem to work ok. I don't notice any improvement or change
by jiggling the bandswitch knob.
My only attempt at repair, so far, has been to remove the top and bottom
covers and re-seat all of the circuit boards I could find that had
the pin connectors. I did that yesterday, but still experienced
drifting/jumping afterwards.
