Review on Ranger SRA-198 Noise Canceling Mic for CB Ham Radios - 4 Pin Wired by Troy Robinson

Passive (without battery) and noise cancelling. I use two of them. One in my personal car and the other in my work truck. The noise cancellation feature of this mic allows me to get maximum modulation (mic gain) without clipping, distortion, or on-air feedback. I get clear audio on my talkback. My main radio is a Galaxy DX979 and it's tuned, tuned and aligned. You are also welcome to use this with any standard radio. Works well with ham radios or any radio with a 4 pin plug.
