[Elecraft] Re: KRX3 Audio Seems Down a Bit from the Main Rx

[wayne burdick]

In K3 firmware revision 2.67 we introduced a new feature that may have 
some bearing on this issue: independent sub receiver antenna selection 
for diversity vs. non-diversity. It may have defaulted to AUX in either 
case. If you didn't have an antenna connected to the sub's AUX input, 
you would have no input signal for the sub receiver.

If you want the sub receiver to use share the MAIN antenna path, just 
go into BSET and tap ANT until you see MAIN. You can set this up 
differently for diversity and non-diversity use of the sub receiver. 
The K3 will store both settings.

A related feature also added in rev 2.67: if the sub receiver is turned 
on, holding RX ANT will alternate between AUX and MAIN for the sub's 
antenna. This is faster than using BSET.
