I just aquired my second K2. It's and older one with a 3 digit serial number that I purchased used.
Plans are to build and install a KDSP2. In preparation for that, I upgraded from firmware MCU2.01 / IOC1.02 to MCU2.04 / IOC1.09. Now I've lost the transmit sidetone. Toggling between sidetone source U8-4 and U6-25 makes no difference. Replacing the old firmware restores the sidetone. What am I missing? Is there a mod to the control board I need to make? I haven't been able to locate any info. Any ideas? Thanks.
