The H-350 will NOT work on radios like the PRC-126 that have the 6 pin U-183 connector.
When the Push To Talk switch is pressed it does two things:
- Connect pin C to ground (pin A) for the Push To Talk function just like on the H-250 handset.
- Grounds (pin A) the microphone while the hot microphone line (pin D) is still connected, pin F also is grounded.
Do you want the H-250/U or the H-250/VCEB
