Re: [Elecraft] KPA-1500 tuner question
We're looking at this right now. It must have crept in with a recent release. I'll post here as soon as I have an update.

Support got back to me. The tuner firmware guy is looking into it. Stay tuned... Walt, WA1KKM On 2/21/19 5:33 PM, Peter Dougherty wrote: This is exactly what happened to me. Very annoying.

Re: [Elecraft] KPA-1500 tuner question
My KPA1500 tuner responds to CAT commands from my Flex radio and doesn’t miss a beat. So CAT seems to be fine but AUX connection is “intermittent”?

Re: [Elecraft] KPA-1500 tuner question
If HiSWR AUTOTUNE is enabled, this would be the expected behavior. However, ATU switching at the start of transmission sometimes happens even with it disabled. Elecraft is working on the ATU firmware in relation to this issue. I noticed it some time ago. Even with the HiSWR AUTOTUNE turned off and AUXBUS frequency data from the K3, the ATU sometimes switches when transmission starts. I don't know quite what it sounds like on the other end, but I seem to get asked for repeats off when it happens. Although the K3 sends frequency data to the KPA1500 only once per second, that isn't the main problem, as the switching occurs even if tuning has stopped for longer than that. Stay tuned. 73, Scott K9MA On 2/21/2019 09:36, Jim Miller wrote: Things to check Could be bad aux cable. Is it from Elecraft? Do you have anything else connected to aux?
