just joined, need assistance with a deaf Syncal 30


 

Hi:
I had working Syncal 30 TRA 931 sitting on my bookshelf for about 10 years.
I decided to check it last week. I believe it transmits fine, but the rx is completely deaf. It has white noise but
otherwise completely deaf. Can anyone point me to any trouble shooting hints ?
If I remember correctly when I got the radio the tx/rx relay was flakey but a little tweaking and it was fine.
I already checked all 4 SPDT sets of contacts, and they seem to be working fine.
