Poor quality product.
Did not use this microphone for several weeks, when I did it onluy worked for a short time. Was past the 30 days to return, which is my fault entirely. From past experience with Road King microphones nnever any issues with quality. Will purchase somethinnng different in the future.

Works Perfectly on Yaesu FT-7B
The mic came pre-wired for older 4-pin Yaesu radios and works perfectly on my FT-7B — delivering clear audio and driving the radio to full power on SSB. It feels well built. Pinout: Pin 1: Ground Pin 2: Microphone Pin 3: Push-to-Talk Pin 4: RX Enable (not used on Yaesu)
