[Elecraft] KAT500 operation?

[Cady, Fred]

Hi Mike,
Does the KPA500 follow the band switching and display the correct band on its LCD?  That would mean that the band data is getting through the cables.  The KAT500 uses the AUXBUX (pin 2 in the 15-pin cable) to get the frequency information in addition to the band data pins.  You might check your K3-KAT cable to see if that pin is OK.

You might try going through all the KAT500 configuration screens to see if something looks amiss and then open the Operate screen.  (In the KAT500 Utility).  That screen is VERY useful to help you figure out what is going on.
73,
Fred
