[MRCA] BC-223 Help

[Brian Roberts]

Hello Gents---

Can anyone on the reflector help me with a BC-223?   I have RF at the 
oscillator and PA stages, but no output at the antenna terminals.   The 
antenna relay works and there is continuity through the contacts.   I 
suspect a faulty or molested TU-18A.   Can anyone tell me the ins and outs 
of the TU-18A--especially regarding the variometers--and has anyone seen 
similar problems with the unit?     Would there be any working TU-18As (or 
any other tuning unit I could use for testing) out there for sale?   Thanks.
