INOP MIKE LEADS TO PLTDEV.

Narrative

I LISTENED TO THE LNS ATIS. THE RECORDING WAS THE LAST OF THE NIGHT BEFORE; THE TWR CLOSES AT XY00 PM AND RE-OPENS AT XB00 AM. I SAID TO THE PLT IN THE R SEAT; THE TWR IS PROBABLY OPEN AND I PICKED UP THE HAND MIKE AND CALLED GND; NO REPLY; I CALLED AGAIN AND STILL NO REPLY. I SAID I GUESS THEY ARE NOT IN. I TAXIED TO RWY 31 FOR RUN-UP. I COMPLETED MY RUN-UP AND CALLED TWR; NO REPLY; I CALLED AGAIN; NO REPLY. I SAID I GUESS THEY ARE STILL NOT IN. I BROADCAST IN THE BLIND; LANCASTER TFC; ACFT X DEPARTING RWY 31. I TOOK-OFF NORMALLY MADE A R TURN TOWARD ALLENTOWN; MY DEST OF 50 MI. I CALLED READING APCH FOR RADAR SVC SINCE I WOULD BE CLOSE TO THEIR AIRSPACE. I GOT NO REPLY. I SAID SOMETHING IS NOT WORKING ALTHOUGH I WAS HEARING MY SIDETONE IN THE SPEAKER. I TRIED THE OTHER COM STILL NO REPLY. IT MUST BE THE MIKE. I PLUGGED IN ANOTHER MIKE AND CALLED ALLENTOWN APCH; THEY ANSWERED AND I APCHED AND LANDED NORMALLY. IT WAS A BAD MIKE. AS I WAS ROLLING OUT; ALLENTOWN TWR SAID; CAN YOU COPY A TELEPHONE NUMBER LANCASTER TWR WANTS TO TALK TO YOU. I CALLED LANCASTER TWR FROM THE FBO. I EXPLAINED THE SIT; THEY SAID THAT'S NOT THE PROB; WE HAD AN AIRPLANE TAXIING WITH A CLRNC. THEY ASKED MY CERTIFICATE NUMBER AND SAID YOU CAN EXPECT TO HEAR FROM THE FAA. I SHOULD HAVE QUESTIONED WHY THEY DID NOT ANSWER BEING SO CLOSE TO XB00 AM; BUT IT DID NOT SEEM THAT UNREASONABLE. THE WX WAS CLR BUT A VERY COLD 12 DEGS FAHRENHEIT. IN THE FUTURE I WILL CERTAINLY QUESTION ANY NO REPLY FROM THE TWR AND TRY ALL MIKES AND ALL COMS BEFORE ASSUMING THEY ARE NOT THERE. SUPPLEMENTAL INFO FROM ACN 296099: LNS ATCT OPENS AT XB00L; I CAME IN TWR AT XA45L. NO RWY OR TXWY LIGHTS WERE ON FROM PLT ACTIVATION. I DID ATIS; CHANGED LIGHTS TO TWR CTL AND ACTIVATE ON; SELECTED FREQS AND AT XB00L ANNOUNCED TWR OPENING. AS I RETURNED TO LC POS; I OBSERVED ANOTHER ACFT ABOUT TO ROTATE; DEPARTING RWY 31. ACFT VERY POSSIBLY COULD HAVE CALLED ON 120.9 CTAF PRIOR TO XB00 AS TO TAXI. I INITIATED RADAR TRACKING BY MDT TO RDG TO ABE. I REQUESTED PLT CALL LNS TWR. PLT CALLED AND STATED; HE DIDN'T KNOW HOW RWY LIGHTS CAME ON BUT HE HAD BROADCAST ON 120.9. CAUSE; POOR PLTAGE; TRAINING; CURRENCY.
