Making HT cables for the URC

I’m pretty confident these cables will work with any of the Baofengs/Quansheng etc. that use the dual-jack microphone connector as they would all be wired the same way to use a standard external Mic.

Regarding the cables, you need:
3.5mm stereo (TRS) to 3.5mm stereo (TRS) jack plug wire – these are often off the shelf wires used for external speakers on phones

3.5mm stereo (TRS) to 2.5mm stereo (TRS) jack plug wire – I use one of the standard wires above, cut in half and then solder a 2.5mm jack plug to the end ( i can then make 2 out of one)

When you wire these just connect tip-to tip, ring to ring and sleeve-to-sleeve. the front panel sockets are labelled ready to accept the wires with the correct internal config.
