Don, Thank you for your input. I would also want band switching to work with both. I know if I shut off the 2.5KFX it is bypassed. The issue is to control both, with one or the other shut off. I operate lots with the 2.5 shut off. I also have the P3, which shouldn't be an issue, I would think. I need to get the KPA-500 soon so the other half doesn't notice too much change and before she retires. Have been loading up the shack if you know what I mean. :-)
Also, I have not resolved the KX-1 question yet, so when I get time will try one more time and if not successful will send to you. I am not about to retire, so am so busy I have trouble keeping up with all the great Elecraft stuff that I keep adding just so I have it. I even miss updates unless I am a beta tester. If I get the beta it avoid so much of the watching the list. Most beta's are perfect.

Of course that simplistic solution would require that both amplifiers have an input signal line to place the amp into standby remotely - many do not, but modern amplifiers should IMHO. Older amplifiers typically have only a front panel switch. 73, Don W3FPR On 2/15/2011 6:15 PM, Bill K9YEQ wrote: > Wayne, > > I have my THP HL-2.5kfx, is there a way to control both via the K3?
