Narrative:

In cruise flight midway from cmh to dtw (direct, IFR flight plan), I began transmitting (as reported by ATC) carrier-only, no voice. The radio in the airplane was receiving all communications clearly. Tried to remedy problem by using both radios, all microphone jacks, 2 different headsets, and a hand-held microphone. Checked all circuit breakers and turned radio off and on again with no results. Communicated via transmitter clicks and transponder idents from cruise and received approach, landing, and taxi clearance via this method. Once on ground, called maintenance (from dtw) and received no solution. Called TRACON and tower (dtw) for coordination of a possible departure. TRACON formulated a plan for an IFR part 135 flight with possible transmitter malfunction. Received IFR departure clearance from dtw tower via remote radio. Using a combination of cell phone, light gun signals, transmitter clicks, transponder idents, and tower radio xmissions. Received and acknowledged taxi and takeoff clearance as well as en route, approach, and landing instructions and clrncs (back to a cmh arrival).

Title: NORAC TFC, UNABLE TO XMIT ON VHF, LANDS AT DTW AS SCHEDULED AND, WITH ATC'S ARRANGEMENT, FLIES UN-REPAIRED ACFT BACK TO HOME BASE AT CMH, OH.

Narrative: IN CRUISE FLT MIDWAY FROM CMH TO DTW (DIRECT, IFR FLT PLAN), I BEGAN XMITTING (AS RPTED BY ATC) CARRIER-ONLY, NO VOICE. THE RADIO IN THE AIRPLANE WAS RECEIVING ALL COMS CLRLY. TRIED TO REMEDY PROB BY USING BOTH RADIOS, ALL MIKE JACKS, 2 DIFFERENT HEADSETS, AND A HAND-HELD MIKE. CHKED ALL CIRCUIT BREAKERS AND TURNED RADIO OFF AND ON AGAIN WITH NO RESULTS. COMMUNICATED VIA XMITTER CLICKS AND XPONDER IDENTS FROM CRUISE AND RECEIVED APCH, LNDG, AND TAXI CLRNC VIA THIS METHOD. ONCE ON GND, CALLED MAINT (FROM DTW) AND RECEIVED NO SOLUTION. CALLED TRACON AND TWR (DTW) FOR COORD OF A POSSIBLE DEP. TRACON FORMULATED A PLAN FOR AN IFR PART 135 FLT WITH POSSIBLE XMITTER MALFUNCTION. RECEIVED IFR DEP CLRNC FROM DTW TWR VIA REMOTE RADIO. USING A COMBINATION OF CELL PHONE, LIGHT GUN SIGNALS, XMITTER CLICKS, XPONDER IDENTS, AND TWR RADIO XMISSIONS. RECEIVED AND ACKNOWLEDGED TAXI AND TKOF CLRNC AS WELL AS ENRTE, APCH, AND LNDG INSTRUCTIONS AND CLRNCS (BACK TO A CMH ARR).
