So today a care package arrived from Noble Radio. A 450Hz CW filter. A true work of art. I did not delay in installing it. Had to do some cleanup on the filter card; somebody had done a messy remove of its original filters - all except the standard 2.3kHz SSB filter. Possibly my Ebay seller. After all, why sell an INOP rig full of expensive separately-saleable filters?
It works great. Single-signal CW reception.
While I was in there, I did the mod that lets the carrier control work with SSB. It's just one wire tacked to two
terminals on the mode switch.
I also fixed the loose coax terminal I mentioned earlier. It turned out that the "clip" part had come undone. Now
it's nice & tight.
Then I did something purely cosmetic: pulled off all the knobs and treated them to an ultrasonic cleaner bath.
Except for the Mode switch and the Aux Program switch. Those don't seem to have setscrews. How do they come off?
The white paint inside some of the pointer knobs - white paint inside a groove - is a bit discolored and perished.
I may want to redo it.
