[Elecraft] New Synths KSYN3As

[Vic Rosenthal 4X6GP/K2VCO]

The TMP cables can be tricky to insert. Make sure all of them are 
plugged in all the way. Since you swapped the synths, the problem is 
likely on the ends of the cables that do not go to the synths.

You have probably checked and double checked the locations of all the 
cables against the diagram in the instructions, but I would do it again. 
The symptom suggests that they are not hooked up correctly.

It might be worth checking the ends of the cables carefully to make sure 
they are OK.
