FYI, When I get too much RF feedback in the shack due to a mistake on my part, it affects the K3 utility. I use it to adjust my RF power in the K3 as my power knob needs replacing. The utility locks up, cannot be closed and requires a computer reboot to restore it. ( I tried Task Manager to no avail.)
I still love my K3. 73, Dave K7DRT -----Original Message----- From: [email protected] <[email protected]> On Behalf Of Curt Nixon via Elecraft Sent: Friday, February 13, 2026 2:13 PM To: [email protected] Cc: Elecraft Discussion List <[email protected]> Subject: Re: [Elecraft] K3S-to-Computer Communication Failure I find that is is happy as long as the k3 is on before launching the comm program Ku8l On Fri, Feb 13, 2026, 12:17 PM Jeff WB0M via Elecraft < [email protected]> wrote: > Hello All, > > A couple of times ny K3S has quit communicating with my MacBook Pro > and macMini.
