[Elecraft] Independent Bands (F/W Vers. 3.03)

[Don Wilhelm]

Bud,

You are attempting to receive with the sub-rx on a frequency that is 
higher than the main RX is tuned to.
The low pass filters are selected for the main TX/RX, and any signals at 
the higher frequency will be attenuated if you are sharing the antenna 
(or ATU) for the sub with the main.

The solution (and what the message is trying to tell you) is to use the 
AUX RX input to the sub-RX.
If you plan operation as you are attempting, I suggest you re-wire your 
SUB-RX antenna to use the BNC connector rather than the unselected 
antenna from the KAT3.

73,
Don W3FPR
