[Elecraft] K3: Firmware 4.48 release - stable, in use?

[Dave New, N8SBE]

Aside from the AGC issue, I found that I couldn't navigate the config
menus from the K3 front panel while HRD was running.

It was hammering the rig so hard that it was hanging the config menu
system.  As soon as I unplugged the cable, I got control of the menus
back.  This was very repeatable.

Again, I never experienced this issue when using LP-Bridge to
intermediate.

73,
