An IFR SR22 and other flights in the vicinity were unable to communicate with the Tower at ILG. The reporter continued on his IFR clearance; landed without incident and was able to contact ground control. A short time later communications on the Tower frequency were re-established.

Narrative

I was flying IFR to ILG. Near the IAF I was cleared by Philadelphia Approach for the GPS-19; and told to switch to Tower frequency. I made the switch; called Tower on COM1. I'm at JIGUP; the IAF. Nothing. Called again - Silence. I dial the frequency into COM 2; try again. No response. I make a position announcement. I hear another aircraft that is VFR and wants to transit the Class D call the Tower. No response for him either. A third aircraft tried to contact the Tower with no response. Now I'm at the FAF. I check the TCAS for nearby traffic - there is none. I considered switching back to Philly approach; but the approach freq was pretty busy and I was already on the glide slope. I also didn't want to miss the Tower calling me back while I was discussing the situation with approach. I was hoping that maybe the Tower controller was tied up on a land line and would call me when he was done. I continued to the FAF and beyond; making frequent position calls. I looked for a light signal from the tower. None. Land; look over to see if anyone is in the tower. Lights are on; movement is present. Switch to ground frequency; and get a taxi clearance. The ground controller seemed nonplussed that an aircraft had suddenly appeared on the field. I reiterate what happened; the ground controller thanks me and says that they will check the equipment. All frequencies were in working order twenty minutes later for my uneventful return flight.
