[Elecraft] K3/KAT500/XV integration

[GWK]

Jack;

In my setup, the XV is connected to 12V, but is not "on" until it is 
selected by changing the K3 to 2 meters (which, of course, is just what 
it won't do.)  The KAT500 is normally left on 24/7.  I do not use the 
"Auto" selection on the KAT500, so it can't surprise me with an unwanted 
tune.

You think a straight-through (Y) cable will work?  I'll have to make one 
and try, if I can find some DB15's.

Thanks for the info,

George

They can be powered on at the same time, but the task needs to be done before the K3 enumerates the Auxbus, which is done in the latter part of its power-up sequence.

This is needed to cause the KPA500 to drop out of transmit. You don’t have a KPA500, but you do have an XV144 connected to that port, which will also drop out of transmit at that time. While you probably won’t see this issue, it is best to use a real AUXIO Y cable (15 pins straight through between all three connectors) to connect both peripherals to your K3.

Having to plug and unplug control cables to switch from HF to VHF is a non-starter.  I had hoped to pick of the control for the XV144 from the "AMP" socket on the KAT500, but when this is done, I get the message "turn on KAT500" on the K3 display, and nothing works until the plug is removed from the XV144.
