[Elecraft] KPA500 Power On

[Phil Hystad]

I don't know much about hooking multiple transceivers to the KPA500 (I only have the K3/KPA500 mix) but it would not surprise me to learn if the problem might be connected with some status check or something that is expected from the K3 if the K3 is indeed connected or maybe had been connected.  A complete power cycle would clear that kind of thing.

Is the KPA500 really designed to work with multiple inputs even if they are switched?  I would be interested in knowing since I also have a KX3.

The station is set up just like the diagram on page 147 of KE7X's KX3 book. This configuration seems to work very well. However, I've recently noticed a very occasional anomaly with the KPA500. Every once in a while, I go to power it on and nothing happens. I have to reach around to the back panel rocker switch, turn it "Off" and then back on. Then, the front panel power on button brings the amp to life. So far I've not been able to track it down to a particular sequence of operating events that precedes it. In the past 3-4 days, this has happened maybe three times.
