Narrative: I departed ZZZ; climbed normally; received vector for a right turn to a heading of 290 and a climb to 10;000. I complied with all of the uneventfully. West of the airport was cell of precipitation that I couldn't see through. It was depicted as yellow on my weather display. The precipitation was west of the airport and oriented along the axis of about 290 to 300 west of ZZZ.I was doing the ZZZ4 departure. The tower controller advised in the initial climb that in substance that I'd be boxed around on vectors for the climb before being going to the route.A previous departed reported the ceiling at about 6;500 which was basically true. I changed frequency to ZZZ TRACON and got a heading of 290. When I entered the IMC the rain was very intense and it was turbulent. I noticed changes on the vertical speed indicator up and then later down. The temperature was near freezing; but I did not see any actual ice. While climbing in IMC; the radio frequency began to screech such that I couldn't hear anything. That ultimately occurred on both radios and both frequencies. The marker beacon lights were flashing. I received a traffic alert for traffic on my left. It was very turbulent; but I stayed at 10;000 feet as assigned. With no communications (coms); I squawked 7600.I decided to turn 90 degrees right still in IMC because that resolved the traffic; would get me out of the precipitation; was a heading basically on course; was consistent with the expectations from the departure briefing and ZZZ4; and would restore coms. The precipitation was aligned with the vector so remaining on that heading was not viable. There was traffic there. I didn't change altitude (I was at 10;000 ft. the whole time).After the right turn; I exited the side of the precipitation; I was able to hear ground responding to one of my calls (on COM2 on the bottom antenna); so I went back to the departure frequency on COM1 (on the top); re-established communications and departed.The ATC TRACON controller was upset seemed to think that I was in VMC and just turned randomly or something. I've flown through 'yellow' precipitation many times uneventfully. The lost coms procedure when you're on a vector is to either stay on the vector or turn on course. I turned on course because it solved all of the problems; but seemed to surprise ATC. I think that the confusing thing for ATC was that it was fine weather straight over the airport; which is probably what he has on his computer. But west of the airport was unexpectedly intense rain.I'm not sure that this incident could have been avoided given what everyone knew at the time; although once I squawked 7600; the turn on course shouldn't have been a surprise.




Synopsis: SR22 pilot reported a loss of communication due to moderate weather during departure.
