A320 captain experiences lost communication on departure due to a stuck mic that is annunciated by ECAM as 'VHF1 emitting'. The problem transfers to VHF2 when that radio is selected and eventually clears on its' own.

Narrative:
Just after takeoff when attempting to contact departure control; we received the ECAM 'VHF1 emitting.' we continued with the departure procedures; watched for traffic and continued to contact departure control. At level off we tried both our radio management panel (rmp) and audio control panel (acp) without success. We then received another ECAM for 'VHF2 emitting.' having one of our captains in the jump seat I had him try the third radio while I accomplished the QRH procedures and squawked 7600. He was able to reach a controller on 121.5; however when instructed to contact ATC on another frequency; we received nothing. After continuous effort for several minutes to reach ATC; our ECAM messages cleared and our radios were normal for the duration of the flight. The QRH assumes there will only be one radio inoperative. My suggestion would be to make a note in the QRH regarding the transponder procedure if there happens to be a total loss of communication. It would also be nice to have a reference page for the lost comm procedure that is found in the flight operations manual.
