Radio acting up

Hello all,

My Becker 4201 just started acting up. Specifically, it has a cyclic regular dead spot when transmitting, so the person listening to you gets about half of each word. It receives just fine, and all functions work as they should. Same thing happens with a fully charged battery or one that has been used for several hours. Has anyone ever run in to this?

Thanks,

Finally got to the radio in my glider and found that with all the instruments on, I am getting a huge voltage drop at the radio when I transmit causing the cyclic drop of the signal. With all the other instruments off and a fresh battery, I have no problems. Also the voltage is dropping at the radio and not the battery. Looks like I need to replace the wiring from the batteries to the panel and redo the wiring behind the panel. Planning on using one battery for the radio, and one for the transponder and everything else. I'm also going to add circuit breakers and run two master switches, one for each battery. Does anyone have any knowledge of the tyco circuit breakers sold by aircraft spruce? They are pretty low cost, but are they cheap?

Thanks,
