[Elecraft] KX3 "DE-Xpedition" - K2N

[Wayne Burdick]

Sounds like fun, Stan.

Hopefully you won't have the three stations right on top of each  
other. But if you do, you'll want to keep the following menu entries  
in mind:

- If you have two or more radios on the same band, set RX ISO to ON.  
This will prevent them from hearing each other's VFO signals in  
receive mode. This setting defaults to OFF since it adds about 10-15  
mA to receive current drain.

- RX SHFT can be set to 8.0, if needed, to reduce or eliminate any  
mutual interference during transmit. Most SDR-architecture receivers  
have the equivalent of RX SHFT turned on at all times, partly for this  
reason. But it defaults to no shift (NOR) in the KX3 to allow the use  
of dual watch and roofing filters. RX SHFT is a per-band setting; you  
might need it only on one band, or not at all.

- If keying one rig activates the carrier-operated-relay (COR) of the  
other(s), you can optionally move their COR threshold up (MENU:COR  
LVL). The default is 0.1 watts. I wouldn't move it too much higher  
than this.

The KX3 takes other automatic protective steps as required. This  
includes temporary reduction of I.F. gain, and turning off the preamp.
