I have a pair of Motorola Talkabout T4500 walkie talkies...One of them transmits a click (transmit) noise every 20 seconds or so....just enough to irritate you...The sound is one that would be made if it was "keyed up" but I have tried every channel and still hear that "click"....Just one the one, not the other.... I have even changed the batteries on both...Please somebody help me, beacause I know this can't be normal...It will scare off all the deer..lol.....David
