Here is why I'm thinking what I posted above...

The above is a portion of a T/Star Schematic - courtesy of CB Tricks - the Switch Side.
Note S2 - C3 - C44...
Now I had someone a long time ago say, why not check the terminals? Wouldn't the relay short out the antenna to XTMR? Well, yeah, but it is not a dead short - it's a RF short but not a physical DC derived Short.
S2 switch - routes from Relay - thru itself - back to Relay Pin 5 to 8 will be shorted in OFF state. But not the outputs.
So 6 and 9 are in the center - 5 to 8 are on the "coil side" or closer to the center. IT would be little harder to check.
So let's look at layout...without the parts...

The above shows routing Green Relay 5 to 8 from SWITCH 2 RED TO SWITCH 1 Relay 7 and 10 (Power OFF)
So they would be the quickest way to check for DC short, but not bad RF routing (burned contacts or Cap failure)
So it's why I mentioned the SWR FWD trick, to determine if one side of the relay contacts are open it makes the rest of the system appear RF-bound as a mistuned cap.
