CHIRP

After doing some research I've hit a wall. I am attempting to disable the PTT button but not the PTT feature. In short i was the radio to rely on a Military PTT for headset instead of using the PTT on the radio and a Mil PTT. The reason for wanting this feature is I'm noticing some PTT dont seat snug and or stay seated so I've resorted to securing them with zip-tie. The issue there is for a good fit it needs to sit on the PTT button on the radio its self. This is something I am attempting for a UV5R in particular but im sure other Feng users have the same issues.
