Grant,

Re-do the S-meter Cal on the main receiver.  There seems to be some 
confusion on this topic, but there is only *one* set of S-meter 
calibration settings (at least that is the way it is right now).  So 
when you thought you were calibrating the subRX S-meter, you likely 
messed up the settings for both the main RX and the sub - I can't say 
for certain but I think it has something to do with the 3 dB pad and 
athe variety of ways to connect the subRX antenna..

73,
