Narrative:

Departed air strip 5400 ft MSL. WX was VFR, 1 day after 3 day snow storm. The first leg of flight was 90 mi to igm flying on a 245 degree heading. I started to fly over broken clouds below. I was ascending to 6500 ft. I still could not get a good signal from igm VOR. The cloud cover below started to close up completely. I was watching my time versus climb speed. At approximately 45 mins, I should have been on top of airport, but never received VOR signal. I tried unicom frequency but could not send or receive. When I finally had clearing below I was over unfamiliar terrain. I tried edd VOR but could not pick up reliable signal. I was flying at 7500 ft. I was then navigating over a populated area, trying to get my position with a sectional. I saw a large airport approximately 3 mi to my south -- it was las vegas, nv. With no radio, or VOR inoperable, I climbed to 9500 ft and flew a large circle heading southeast to a small airport. I idented the airport to be 0l7, jean airport. Landed, fueled and my radios started working. I naved to hector VOR with a good signal and flew home. I took it to an avionics shop and had a new GPS installed and antennas checked. They said all the snow and water probably shorted signals.

Narrative: DEPARTED AIR STRIP 5400 FT MSL. WX WAS VFR, 1 DAY AFTER 3 DAY SNOW STORM. THE FIRST LEG OF FLT WAS 90 MI TO IGM FLYING ON A 245 DEG HDG. I STARTED TO FLY OVER BROKEN CLOUDS BELOW. I WAS ASCENDING TO 6500 FT. I STILL COULD NOT GET A GOOD SIGNAL FROM IGM VOR. THE CLOUD COVER BELOW STARTED TO CLOSE UP COMPLETELY. I WAS WATCHING MY TIME VERSUS CLB SPD. AT APPROX 45 MINS, I SHOULD HAVE BEEN ON TOP OF ARPT, BUT NEVER RECEIVED VOR SIGNAL. I TRIED UNICOM FREQ BUT COULD NOT SEND OR RECEIVE. WHEN I FINALLY HAD CLRING BELOW I WAS OVER UNFAMILIAR TERRAIN. I TRIED EDD VOR BUT COULD NOT PICK UP RELIABLE SIGNAL. I WAS FLYING AT 7500 FT. I WAS THEN NAVING OVER A POPULATED AREA, TRYING TO GET MY POS WITH A SECTIONAL. I SAW A LARGE ARPT APPROX 3 MI TO MY S -- IT WAS LAS VEGAS, NV. WITH NO RADIO, OR VOR INOPERABLE, I CLBED TO 9500 FT AND FLEW A LARGE CIRCLE HDG SE TO A SMALL ARPT. I IDENTED THE ARPT TO BE 0L7, JEAN ARPT. LANDED, FUELED AND MY RADIOS STARTED WORKING. I NAVED TO HECTOR VOR WITH A GOOD SIGNAL AND FLEW HOME. I TOOK IT TO AN AVIONICS SHOP AND HAD A NEW GPS INSTALLED AND ANTENNAS CHKED. THEY SAID ALL THE SNOW AND WATER PROBABLY SHORTED SIGNALS.
