[Elecraft] KPA500 Power On

[Jack Brindle]

Jim, the key question is what version of firmware is in your KPA500. This is viewable in the menu, under the FIRMWARE selection.

Also, what is your RADIO selection in the KPA when using it with the KX3?

If you do not have the latest firmware, I would advise you to upgrade. There was a bug fix that affected this some time back.

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.
