Kyle,

1.  First, be sure that you are, in fact, supplying the FS keying information 
to the 920 before suspecting the rig.  If you have an ohm meter, put it 
across the leads that you are connecting to the FSK jack on the 920.   Depending on 
what your sending, the meter should either show a short on keying or show 
SOME fluctuation.  If you are not getting any indication that the FSK contacts 
are being shorted for the duration of the mark tone, then you will have to 
correct that problem -- which would be from the output of your computer or your 
Terminal Unit.  

2.  If you are getting an indication with a meter that the contacts are being 
supplied with a short when needed, then you need to be sure that you are, in 
fact, able to FSK the 920.  Make a contact on phone.  Tell the other operator 
that you will be sending a carrier and that when you touch a couple of wires 
together, the carrier frequency should shift slightly.  For this test, it would 
be best to set the 920's FSK to USB.  However, the other guy should be able 
to tune around and hear your carrier and detect a shift in it when you touch 
the wires together.   Then, go back to SSB and listen to what he tells you.  

If you are unable to shift the frequency in this way, that would indicate 
that you still do not have the 920 set up correctly, or, it isn't working right.

3.  If you don't have  a small VOM with you, get one at Radio Shack and put 
it in your travel kit.  If you had one with you, you would be able to easily 
solve this problem. 

I'll be interested to see what you find.

Good Luck!
