I have a UHF CXB R2 5K that I am having some issues with. I have no TX output at all. VCO (both TX/RX locked) on the SSCB the PA on light is off, if i push the xmit switch I get a real fast blink of the PA on, PA key lights.
Now I have taken my ft-60r ht and the PA by itself and was able to make output. so i know it is getting dc power fine.
what am I missing? what *could* be the issue?

Watch out for the PA sense cable connection to the board underneath the RF tray. That's ****ed me more times than I can count.
You might also want to take the RF board out of the RF tray and inspect the passthrough connectors. If there's black crud built up around the base of the pins that can also cause a false PA fail indication.

now to do the fine tune, and find all the control lines so I can hook it to the RC-210
