I've got a K3/Mini running, remotely operating a K3 - but I have two major audio problems if I use the K3 Mini cable to connect the Mini to the RRC, and then plug my Heil headset into the mini:
1. Headphone audio is down 20 db compared to plugging headphone into the RRC.
2. On xmit, horrendous hum on the xmit audio - which goes away if I plug the mic directly into the RRC.
Elecraft has sent me a new I/O board for the Mini, I will see if that fixes the problem - but others have had the problem and the I/O board did not fix.
Is anyone out there seeing success plugging a headset into the Mini, either using the 8 pin circular connector and the 1/4 phone jack on the front panel, or using the side min phonos?
