Narrative:

After taking off and entering IMC conditions in heavy rain. The pilots lost intercommunications between pilots; lost communications on radio one. The copilots yoke started to fall apart; which resulted in a stuck mike on the aircraft. The copilot switched to communications on radio two; the captain was able to communicate with ATC on radio two intermittently; (I feel that p-factor with static electricity from a loose static wick or bracket connections may have been an additional problem). I chose not to continue the flight into night IMC. Due to the poor communications on radio #2 I climbed 500 feet above an altitude assigned. (Due to poor communications) I returned to the departure airport; prior to returning I had to dump fuel to get below maximum landing weight.
