[Milsurplus] [armyradios] PRC-138 problems

[Joseph Pinner]

Again, thanks for all assistance!

Here is where I am:

1  Receive seems to work at specs

2  Attempting to transmit results in a Tune Fault

3  Disabling Coupler there is 20W output on High Power into dummy load

4  Running through full Test results in No Fault

5  With Coupler Enabled and doing SWR test into dummy load results in
     Tune Fault but 1.1:1 SWR indicated.

     Could A1 discriminator on A9 Coupler board be bad?

     Any Coupler troubleshooting tips. No obviously burned coils.
