Actually, this sounds like a question that should be answered by Heilsound. You may have a non-working microphone or you my have an adapter that will not work with the K3. Both the ProSet-iC and the HandiMic-iC should need bias if I recall correctly. The K3 provides bias on the AF pin, and that Kenwood cable may include a blocking capacitor (which would render the K3 bias ineffective) and depend on the voltage at Kenwood pin 5 to power the element (the K3 has voltage on pin 6). What I am saying is that only Heil can provide the right answer - they do not publicize the schematics for their adapters and cables. Unfortunately, HeilSound in the past has stated that Elecraft is the SAME as Kenwood, but actually it is not the same - it is "compatible" but that does not make them "equal". The difference is in the use of pins 5 and 6 on the mic connector. Elecraft uses pin 6 for 8 volts, Kenwood uses pin 5 for 8 volts. Bottom line - any mic (or adapter cable) that depends on the Kenwood pin 5 voltage will not work with the Elecraft pinout. As one "for instance", the Kenwood MC-85 microphone will not work with the K3 for this very reason.
