[Icom] ICM Mic element Problem

Fri, 30 Apr 2004 07:43:32 -0400

Fred,

I experimented here with Heil HC4 and HC5 elements on my ProII, and compared
them with a $39 Radio Shack mic and a $29 Plantronics Audio90 computer
mic/headset. After much on-air testing, ranked the Plantronics headset
first, the RS mic second, and the Heil elements third & fourth.

I am interested in your configuration for the RS condenser element - do you
connect it "direct" or with a DC blocking capacitor?
