Greetings

Since this is a group concerning equipment.. I have a question...I have an
IC-22S which has a technical problem...

When in operation, it only operates in simplex....I have the front panel off
so I could follow the wiring easier... The center pin, of the +duplex
simplex -duplex switch goes to the diode matrix board.. even the schematic
doesn't help from there...

The outside two wires, acording to the schematic go the other places....

Does anyone know what signals I should see on the outside two wires... I am
not too concerned about whether they are the - or + duplex signals only what
they should be...
