I recently got a new cobra 29 lxle radio and it was set for dead key of 2 watts, ow the problem is after hooking up the radio to my RM KL203-P amp after keying up the mike I have to key the mike 2 or 3 times to get the receive to work so you can hear it. Its like its sticking. When I turn the amp off the radio works fine no sticking. I tried the amp on my general lee and it worked fine no sticking. Any help here would be appreciated
