Any insights on premade cables and/or qb25’s usage for packet use (for a low cost rig on BPQ ports.) ---

I’m not finding a documented pinout for the mic connector, but with tendency of Asian brands to borrow the technology there is a good chance that it is the same [RJ-45 pinout as used in ICOMs](https://forum.digirig.net/t/icom-rj-45-cable-for-digirig-mobile/576), [Yaesu](https://forum.digirig.net/t/cable-for-yaesu-ft-2500m/1085) or [Anytone](https://forum.digirig.net/t/cable-for-anytone-at-d578uv-iii-pro-plus/548). You can test it by checking which pins ring to the radio’s chassis (GND) and which pin has +8V. ---

Well, the Icom plug was a no go. I found this in the forum today. Looks like I may be building my own. ![image](https://forum.digirig.net/uploads/default/original/2X/3/3f7fb4d39be3e03baf8198f9f49ea3250b445586.jpeg) ---

Wait, is this all I need? ![image](https://forum.digirig.net/uploads/default/original/2X/1/1c7b2eb930dded176712181a1b128603c384185f.png) ---

This looks very much like Btech UV-25: > [@Cable for BTECH UV-25](https://forum.digirig.net/t/cable-for-btech-uv-25/205): > > 3.5mm TRRS headset socket in the back has all required signals: [image] Digirig TRRS to TRRS audio cable will look like this: BT tip (PTT) → DR ring 2 (PTT) BT ring 1 (MIC) → DR ring 1 (RIG\_AFIN) BT ring 2 (SP) → DR tip (RIG\_AFOUT) BT sleeve (GND) → DR sleeve (GND) [Manual](https://forum.digirig.net/uploads/short-url/xg46ZF2vdlg7YfUDI9BaYmU5cVO.pdf) (1.1 MB) ---

Note: The manual diagram for the headset socket has the MIC and SPEAKER TRRS [QB25Headphone2DigirigCableDiagram.pdf](https://forum.digirig.net/uploads/short-url/qQeI7Nlk42lGYIfrzLoOlmYZAVI.pdf) (171.0 KB) rings switched and the instructions provided by K0TX works well. Also, I cannot find if VOX is supported. I built a cable, used Digirig Mobile and have successfully used, WJSTX - FY4/FT8, JS8CALL, WinLink, MMSSTV.
