Andy, You've answered your own question.  If it doesn't happen when the entire rig system transmits into a dummy load, but has problems while connected to an antenna; you know where to look. In that search, high on the list of suspects (right up there with failure of any antenna elements)

This is really strange.The only thing I can think of is some kind of feedback to the TS-590s ALC circuitry caused by common mode current on the feedline. An easy test would be to connect a common mode choke at the output of the KAT500 and see if the problem goes away. Does the antenna have

Eugene, The KAT500 will work with almost any radio made in the last 40 years (or somewhat older), presuming the rig has I/O data available. If it doesn't read the band data from the radio ( on it's ACC port), there are still plenty of ways to allow it to do what it needs to do.  The utility

I use KAT500 Utility remotely by running it on a small, inexpensive server computer at the remote station and displaying and controlling it via Chrome Remote Desktop. (There are several equivalent remote desktop programs.) Note that you can not run KAT500 Utility and KAT500 Remote Server at the

Ok, I've done some homework and have a good understanding of the KAT500 and the KAT Utility which seems to have all the functions I am looking for. Next question. If I want to control the KAT500 over ethernet, my understanding is I need to use the Remote server and client applications.

[Elecraft] Power oscillation problem (KPA500+KAT500)

2023-11-20 Thread Andy Durbin
I have a new power oscillation problem that is manifest only on 40 m when using an attic dipole. Basic station configuration is Kenwood TS-590S, KAT500, KPA500. As drive power is slowly increased and output power rises above about 100 W the power output falls to zero then slowly rises again.
