Deluxe speaker microphone for Yaesu Handhelds has a PTT lock (for carrying on long, onesided conversations) -- you won`t wear out your thumb pressing while you talk! It also has a volume control knob that allows you to set it for a super quiet room or noisy environment like a hamfest or banquet.
Recommended for the MFJ-296Y, SPK/MIC, W/VOL, YAESU-R/VX1, IC-Q7
