[Elecraft] K3 mic probs

[Jim Hoge]

Tnx to all that responded. I now have the hand mic working as it should be- all it took was to toggle the mic gain to high. However, the mic of choice will be via the rear panel and it will take some more detective work. The manual says it is a mono jack but I think what threw me was that the microKeyer employs a stereo plug. If indeed it is a mono jack, I will need to jumper the ring and the shield on the stereo plug that terminates the mic cord (other end is a 3 pin XLR). The mic is a dynamic one, a Heil PR-20. It seems to make sense that the low levels of less than stellar audio would be due to the return floating in a trs plug when the ring is unconnected. The shield must be picking up some to give me something. The cable is good so only other option is bad mic but I haven't tried it on another radio yet. Sounds like a project for a three day weekend, hi. 

Does the K3 employ a mono or stero jack for the rear mic connection?

tnx es 73,
