KPA500 REMOTE POWER CONTROL

HI Gordon-- I run a KPA 500 remotely and have the same problem some times. But there's a big green bar at the bottom of the utility that sez "power on". That should be your first indication. But its hard to know what's going on at the remote site. I use a 'remote rig' setup to run the radio and the COM1 port to talk to the KPA 500 and for power on and off I use a set of contacts from a microbit webswitch to toggle a short across pin 12 on the ACC plug on the back of the KPA --and that's the same as pushing the power button. The webswitch is very reliable and I use if for other stuff like switching a fan in the transceiver box, KAT500 power and a couple of coax relays. Here's a webpage with some of the info: http://www.valhallatreefarm.com/WB7ELY/kpa500/kpa500.htm

Re: KPA500 REMOTE POWER CONTROL

KPA500 AUX Pin 12 is GND. AUX Pin 8 is the KPA500 remote power ON/OFF
pin. No webswitch is necessary to remotely power the KPA500 on and off,
since this can be done quite easily from a button on the K3 itself, using a
macro, as described here:

Re: KPA500 REMOTE POWER CONTROL

Bob, That is a great plugnplay line of boxes you make!. Commendations to you for your inventiveness and marketing. However, I am not a 'plugnplay' ham and needed to figure out how I could wire something up myself. We talked early on in 2017 when I was first putting together my remote rig system and you had all the solutions for connecting up any combination of assorted shack necessities. But I I am not running a K3, I'm running a Kenwood TS-480 and feeding a KPA500/ KAT500. So I used a microbit webswitch to perform the shorting of pins 8+12 on the KPA to turn it on and off http://www.remoterig.com/wp/?page_id=166
The microbit 1216 is a great little box with five relays. I use the other four relays for a fan in the 'radio box' power to the KAT500 and a pair of coax relays. webswitch has not missed a beat in three years. Some photos and hookup on my projects page: http://www.valhallatreefarm.com/WB7ELY/newprojects.htm
