Narrative:

During a flight after maintenance, we lost communications on both communications. We used our emergency handheld xceiver and established contact after approximately 5 mins. ATC said we had a stuck microphone. However, we had both transmitters set on different frequencys and still could not transmit or receive. This was a problem after maintenance on the ground run and was corrected by maintenance prior to this flight. After about 10 mins, the radios started working again. Maintenance found a bad pin in a connector.
