Yes it is polarity concious. If you look at the capsule 2 connection pads, you will see that one of them have tracks to the casing. That is the negative one. The one that has no tracks to the casing is the positive one.?

Thank you , Timothy

I am not using a Dynamic mike, I am using the small electret mike as was supplied with the kit.
I make up the mic with a plastic enclosure and a switch for the PTT.
4 wires, 2 for the PTT and 2 for the Mic.

Just a thought - how important is polarity on the mic ? (could it be that I have switched the Pos and Neg ??)

Have been running the rig on a 13.8 DCV regulated power supply with a 2amp fuse.
