[Elecraft] KAT500 remote

[rocketnj at gmail.com]

You could possibly look at Node Red which runs on a Raspberry Pi. I use it with a KPA1500 and I know there is a flow (programming) for the KPA500 as well. The Pi runs on your home network and you use a USB to serial cable from the KPA500 to the Pi. You can control and monitor the amp from any web browser.

If you are interested we have a Google Groups.io site https://groups.io/g/nodered-hamradio

Here's a picture of my Node Red dashboard. The panel on the left is for the KPA1500. The layout is customizable.

Subject: [Elecraft] KAT500 remote

I use the KAT500 remote software and it works great. I have only one problem with it, I can not tell if the power is on or off. This matters because when the remote site looses power the state of the KAT500 is unknown and the program does not indicate if the power is ON or OFF.  Is there a way to tell?

I can keep trying the POWER button then the TUNE button until it works, but it would be much better for a positive indication of the power state by button color or some other indication in the application.

I have set the "Initial Power" in the KAT500 utility to be "Power On" 
when DC  is applied, but not sure this is always observed.  I have no other way to see the remote site when this happens.

Any suggestions?
