[Elecraft] K3 integration with KPA500 and KAT500

[Jim Brown]

Hi Andy,

I've owned a KPA500 since soon after it's introduction, and am currently 
using a KP1500 borrowed from a neighbor who is in Germany for WRTC.  
I've never used the ACC cable between K3 and either amp -- the operation 
of frequency-sensing circuitry requires no more than a tap on the mic or 
a dit to switch bands.  The auto-tuner built into the KPA1500 is 
spectacularly good, remembering multiple tunings per band per antenna 
output. The KAT500 tuner is also quite good at detecting frequency.

73, Jim K9YC

The reason to buy a K3 or K3S is because they are superior radios, but I 
wouldn't factor integration with
