This is an ideal solution for taking you handie mobile in the car where you may have it in a phone holder or airvent mount with external antenna connected.
This mod works only on the twin plug Kenwood standard ( Bumfeng,TYT,HYT, ...yeah, the chinese stuff) I tried this on a 3quid Baofeng S/M (as that's all they're good for --- experiments....absolute rubbish otherwise)
It's just a case of wizzing off the 2 end conductors on the 2.5mm (small pin) plug. AT YOUR OWN RISK I used a Dremel cutting disc.
Leave as much length on the stump as possible , to ensure a good contact in the socket. It may be possible to actually leave the middle contact intact as well, and just wizz the tip off, as this middle contact is not used for the S/M anyway. I only had the one to experiment on, so if someone tries that and it also works, please leave a reply here.
Happy Butchering !
