[Elecraft] KAT500 - can't change antennas on 6 meters

[Dennis Moore]

I'd still suspect the config settings, this test just showed that the 
KAT-500 is doing well mechanically. The tuner is getting a signal from 
the K3 telling it what band you're on so appears to be limiting your 
options based on that band. You can repeat the mode/ant test with the 
radio off, you should get the same results as with the control cables 
disconnected.

In the utility, Edit Configuration, Antenna tab, go through each of the 
band settings and enable whatever antennas should be available on that 
band. If you've already done that and it still isn't working right, I 
don't know where to go next.
