In cruise climb to 7500 MSL the ELT in the aircraft activated at approximately 7000 ft MSL. PIC was unable to deactivate ELT due to lack of remote switch in cockpit. PIC was also unable to transmit/receive via VHF, because frequencys were blocked by ELT xmissions. PIC contacted btv AFSS, via cellular phone, airborne, to advise of communication failure and ELT activation and that crew/aircraft were not in distress. PIC returned to departure airport (uncontrolled) to deactivate and re-arm ELT. Mechanic looked at problem and fixed suspect wiring. PIC later departed and flew 8 plus hours without further incident.
