i didnt know where to post this ..sorry if its in wrong section(couldnt find a 2way radio, walkie talkie section)
i was wondering if anyone here knows availability of any two way radios/ walkie talkies where you dont have to push & hold the button to talk ? e.g need one that allows for a proper 2 way conversation (like on a regular phone) without having to like having to wait for other person to say 'over' or 'roger' I hope you know what i mean- thanks
