RC, No, they are not interchangable. The impedance is the problem. The unamplified D-104 (and other Astatic crystal [or ceramic] element mics needs a high impedance to work into and sound good. The K2 and K3 have a low impedance input. If you have the amplified D-104, then it will drive the

I got a buddy of mine to get on 6m this evening to try out the mic on SSB. He said I sounded just fine. I did not adjust any settings, I had it on full mic gain and compression the whole time. I was able to get 10-12 watts out (off the meter on the rig, didn't hook it to an external meter/monitor)

Steve, The only thing I can say is that there is more than enough audio drive with my MH3 microphone. Does your MH-31 work with plenty of audio on your FT-817 or FT-857? My numbering scheme was consistent with a left to right convention looking into the jack opening (like the diagram in the FT-
