The manual I referred to above 68P81013E65-L ... Receiver sections
68P81026E76 and 68P81026E37 (also see Eric's reference above) cover
the receivers quite well.

The Channel Element required for the receiver is K1005A - 0.0005%
If you have the receiver with the 11.8 MHz shifted IF, the Channel
Element needed is a KXN1022A - 0.0005%
Everything Eric wrote for you above is correct. I just expanded
on it a bit for you.
Hope this helps,
