Batboard

Have a VHF Quantar I am working on.
Has a wireline card and single receiver.

I was having receive issues with it but those are worked out and other than needing the preselector retuned the receiver is good.
Here's the issue, it receives fine now but will not key when receiving a signal.
I do NOT have anything on any connector on the back of the unit.
I assume that there is something required on one of the connectors but I have no idea what that would be, or which connector to put it on.
Also, I can put the station into alignment mode and it transmits fine and creates a 1KC tone for the deviation alignment procedures as it should.

Any thoughts are of course appericated.

Is it progranmmed as a "base" instead of a repeater? You can find it in the programming.

+1

checked that, it's set as a repeater.

Only thing I know for sure is missing is the termination on the 10base-t Ethernet port on the back on the unit.
I am going to fix that but I couldn't see how it would cause this issue.

OK...here is another thing. Does it have a SAM Card? If so disable the MDC/Tone requirement.
If the SAM is programmed and active the repeater won't energize in an active state.

Other option is to send one of us the cp so we could take a look. We could go round and round like this for weeks.

Ok, found something else going on here.
Upon further review, the Exciter and PA are two different VHF splits.
Receiver is working fine.
Unit will TX correctly in alignment mode.
Receive audio is getting to the exciter and coming out the connection to the PA, but the PA is not keying.

Considering full investigation of PA schematics for both splits to see if there is something specifically different telling the control board what split the PA is and maybe changing it.

Any ideas would be great.
