Hi Ross, Looks like you have to switch OFF the bias. Use Main Menu item MIC SEL to do that If the MH2 works OK that means Bias is ON now. For the Heil ProSet (with #4 or #5 dyn. element) you might need the HI range mic gain (you can set that in the same menu). See p.51 of the Owner's Manual (rev.D).
-- Enno, PF5X K3 #1263 I have just received my K3 and have been using it on data, and it is working well, But I have a problem, when trying to use the Heil Proset it receives ok but when I try to use the PTT I get a loud audio noise over the top of my speech, it sounds like someone giving a loud "raspberry". Trying the MH2 hand mic everything works perfectly, there is no noise and using the monitor, my speech sounds normal. The problem with the Proset also occurs if I try and turn on the K3 manually. Ideas please, what have I set up incorrectly, or is it the headset?
