Ken,

 Unless you use a VOX circuit on the RX audio which I do not recommend you will have to go inside. We have used the Baofeng 888's with success as node radios. Info on the mod is in the how=to section at hamvoip.org  I believe the UV5 uses a similar approach.

> Not interested in hacking into the radio's at all for internal
