2024-04-30 - Received new dial glass and found out this is a 66CA. Will start to work on restring of dial and tuneup soon.
2024-03-30 - I have had this radio for a while - it was given to me through a fellow ham - it belonged to a non-ham's Grandmother. It was working shortly before he gave it to me, but the dial string broke. I have ordered some dial string and will get this radio on my bench for testing soon.
Newest project.
30 April 2024 - Works - just needs tune up and cabinet refinished. New dial glass ordered.
April 30, 2024 - Working!
April 13, 2024 - Been working on this little project. Changed out all the electrolytic and wax/paper capacitors so far and did some rough tuning - able to pickup some stations on the built-in antenna, so pretty happy about that. Next Step is to test the tubes.
6 April 2024 - RESOLVED
After sending the transverter to Bulgaria in November and them not receiving it, it was finally returned near the end of March. I let them know it was back and asked if they had an idea on a fix and if I could do the fix. Hristiyan had me check a few voltages before and after performing a test to replicate the issue, he decided there was an oscillation issue - he had me change out a cap (see below circled in red) and that resolved the issue. This will be used as my 902 rover.

I have an issue with my 902 transverter - I am monitoring a 902 CW beacon I built and it's S3 to S5 sometimes at my house - if I switch to a SSB memory in my ICOM 9700 and transmit when I return to the 902 beacon memory I have lost about half the signal or more (usually down to S0) - the only way to get the S3/S5 signal level back is to remove power from the 902 transverter.
See two videos below.
Any thoughts on why this is happening?
