Hi Joe,

Turn on the SUB RX and make sure it says MAIN for the antenna.

Tune in a CW station on Main RX
Press A-B (#3 button) twice.
You should hear the CW station on the SUB and the strength should be
exactly the same as the Main.

Now tune in a SSB station on VFO A
Press A-B twice
You should hear the SSB station on the SUB and it should be exactly the
same strength as the Main.

If this does not work then I think something is not correct with your
crystal configuration for the SUB RX.

73,
