However, with a good external antenna, you should be able to communicate with another aircraft, or airport, 10-50 miles, depending on the height of your airplane. The "muffled" part of the description sounds like a headset or patch cord amplifier problem. If you can, put the "rubber ducky" antenna on the radio and transmit to another airplane, or call the airport, from a mile, or so, away by speaking into the front of the radio (no headset or patch cord). If it sounds clear to the other airplane, or to the airport, then you have a headset problem. If not, you probably have a radio problem. Also, make sure your batteries are fully charged when transmitting as low batteries can cause the radio to sound "muffled" (distorted) while the receiver will sound O.K. (takes much more power to transmit than receive).
