Narrative:

While en route from st marie, wa, to ritzville, wa, the operation of the communication radio became questionable. Since the lights at ritzville were activated by radio xmissions, the ability to activate the runway lights was also questionable. Since I was not able to purchase fuel in st marie, I did not feel I could safely fly from ritzville to the closest runway with lights (geg) if I failed to activate the lights. I decided to divert so spokane. As I approached geg, I was unable to communicate with approach because I could not use their frequencys with the 90 channel radio. I was also unsuccessful with my attempts to raise the tower on 118.3. Since the aircraft was not equipped with a transponder, I decided the better course of action was to proceed to felts field (even though their tower frequency was 134.4, not available to me). My flight guide showed the tower would be open until XA00 hours. I announced my arrival on ground 121.7 and landed on runway 21R. I had hoped geg would have heard my xmissions or noticed my lights and alerted felts field. As it turned out, felts tower was closed (at XX00 hours) and geg claimed I was within their 5 mi airspace and did not hear my radio calls. Had I known felts tower closed at XX00 the entire problem could have been avoided. With the communication failure and fuel situation I feel I took the safest course of action.

Title: A PLT OF A PVT ACFT ENTERED CLASS C AIRSPACE WITHOUT A XPONDER, AND WITHOUT ESTABLISHING 2-WAY COMS, CITING AN INABILITY TO ACTIVATE LIGHTS AT DEST AS THE REASON FOR THE DIVERSION.

Narrative: WHILE ENRTE FROM ST MARIE, WA, TO RITZVILLE, WA, THE OP OF THE COM RADIO BECAME QUESTIONABLE. SINCE THE LIGHTS AT RITZVILLE WERE ACTIVATED BY RADIO XMISSIONS, THE ABILITY TO ACTIVATE THE RWY LIGHTS WAS ALSO QUESTIONABLE. SINCE I WAS NOT ABLE TO PURCHASE FUEL IN ST MARIE, I DID NOT FEEL I COULD SAFELY FLY FROM RITZVILLE TO THE CLOSEST RWY WITH LIGHTS (GEG) IF I FAILED TO ACTIVATE THE LIGHTS. I DECIDED TO DIVERT SO SPOKANE. AS I APCHED GEG, I WAS UNABLE TO COMMUNICATE WITH APCH BECAUSE I COULD NOT USE THEIR FREQS WITH THE 90 CHANNEL RADIO. I WAS ALSO UNSUCCESSFUL WITH MY ATTEMPTS TO RAISE THE TWR ON 118.3. SINCE THE ACFT WAS NOT EQUIPPED WITH A XPONDER, I DECIDED THE BETTER COURSE OF ACTION WAS TO PROCEED TO FELTS FIELD (EVEN THOUGH THEIR TWR FREQ WAS 134.4, NOT AVAILABLE TO ME). MY FLT GUIDE SHOWED THE TWR WOULD BE OPEN UNTIL XA00 HRS. I ANNOUNCED MY ARR ON GND 121.7 AND LANDED ON RWY 21R. I HAD HOPED GEG WOULD HAVE HEARD MY XMISSIONS OR NOTICED MY LIGHTS AND ALERTED FELTS FIELD. AS IT TURNED OUT, FELTS TWR WAS CLOSED (AT XX00 HRS) AND GEG CLAIMED I WAS WITHIN THEIR 5 MI AIRSPACE AND DID NOT HEAR MY RADIO CALLS. HAD I KNOWN FELTS TWR CLOSED AT XX00 THE ENTIRE PROB COULD HAVE BEEN AVOIDED. WITH THE COM FAILURE AND FUEL SIT I FEEL I TOOK THE SAFEST COURSE OF ACTION.
