You have to remember, channel 3 was built LONG before Range based Vox came to AH.
As such it was and still is a good tool. Its just not the tool a lot of AH'ers think it is.
It works perfectly within its parameters. You just need to know what those parameters are to use it effectively.
Personally I use it daily and would HATE to see it changed.
You want range based communications, get a mic.
