After takeoff; during climb phase; clearance was given from ZZZ Approach [Control] to climb restrict to 12.000 feet direct ZZZZZ intersection. When crossing 10;500 feet; ZZZ Approach instructed to call ZZZ Center on frequency XYZ.AB. I did try to call ZZZ [Center] on XYZ.AB several times; but no contact received. I could listen ZZZ Center very weak on XYZ.AB; and could listen the other aircraft communicating. I tried to ask another aircraft for a relay between me and ZZZ Center; but no answer. No answer from ZZZ [Center] also. I tried to contact back ZZZ Approach and ask for a different frequency; but had no answer from ZZZ Approach also. I started looking on my charts and started calling ZZZ Center on other frequencies; but no answer again. I tried to contact XYX.ZB; but no answer also. This was when I realized that I was facing a communication fail. At this moment; I selected 7600 (communication fail code) on my transponder (squawk). Decided to continue the flight following my flight plan clearance received; towards my destination. Over ZZZ1 tried to call ZZZ [Approach] but no answer. During all time I tried to use different radio equipment on board and also keep trying contact with ZZZ Center; ZZZ1 Approach; ZZZ Tower; another aircraft that sometimes I could listen very weak; but no answer.When approaching ZZZZZ1 intersection; on XYX.ZB I started listening ZZZ Center transmitting blind for me a telephone number for me to call. I also could listen if I received the message to press ident; I did. After that; ZZZ transmitted to me; blind again; to turn left heading 270 and descend to 6;000 feet; and asking me to press ident if I received. I pressed ident; and followed the instruction given. ZZZ [Controller] replied that they see my ident; and weather information for ZZZ [Airport] was given to me; together with a VFR approach and landing clearance on ZZZ3 Runway XX; and ident was requested again. I understood and pressed ident again. ZZZ Center said to me to try contact with ZZZ1 Approach on XCY.DZ I tried; but no answer was received again; and I kept monitoring both frequencies; the reception was very weak and noisy. After few moments I could listen a last transmission saying me the weather and clear to land on Runway XX; after landing try to call ground.I did land on Runway XX; and after landing; vacated the Runway via Taxiway 1; stopped and tried to call Ground. Again; no contact. Decided to turn left on Taxiway 2 and look for a place to park. I couldn't see any signal from Tower or follow me car at that time. When I was closer to the Tower; I could listen to Ground calling me; and I replied back. He said he was receiving me too weak. Instruction was given to continue Taxiway 2; hold short Runway XY. Next instruction; cross Runway XY turn left on [Taxiway] 3 and hold short Runway XX. At the holding; communication was lost again. Parking brakes applied. I took my phone; called ZZZ [Center] and asked ZZZ1 Tower telephone number. I tried to call Tower but phone didn't complete the call. After few minutes; I decided to make a 180 turning back; to not cross the runway. I did it and followed Taxiway 2 back; when I received a transmission on the ground frequency saying to turn left on Taxiway 4 and park. This was what I did. After stopping the aircraft; I didn't move from inside until police and the airport ground personnel came to me and said me that I can leave the aircraft. Before leaving the flight deck; I took my phone and called the ZZZ Tower again and after speaking with [the Controller]; situation explained; he asked me to call ZZZ center on phone number given. I did call ZZZ; asked to call with the supervisor. I explained all the situation and the same I am writing here on this report.After all done; I was asked to taxi the aircraft to another apron. I asked to park the aircraft at the hangar; closer to the FBO; where an aircraft technician could help me to troubleshoot and fix the airplane. A follow me car was provided to me and the taxi was done following the follow me car; and aircraft parked in front of the hangar.
Albatross pilot reported that the aircraft's communication system malfunctioned in flight causing weak transmissions and eventually a loss of communications.
