Narrative:

On jun/tues/92, at approximately XX30 pm, I was flying our aircraft en route from hilton head, sc, to greensboro, nc, VFR. I attempted to get VFR advisories from ZJX, at approximately 10000 ft, when ATC advised me that my radio communications were unreadable. After 6 attempts at switching radio controls and headphones to handheld transmitter, center asked me to try florence approach. After 6 more attempts at different radios and switches, I was again advised that my communications were completely unreadable. I declared an emergency landing due to lost radio communication, a yellow annunciator light coming on to indicate low hydraulic oil, and the fact that I was a single pilot with no assistance should I have further problems. Approximately 100 mi south of greensboro, I received the ATIS and reconfirmed the WX was still VFR at greensboro and chose to land at greensboro for the following reasons: 1) it was the airport I use often and was most familiar and comfortable landing at, 2) I wanted to land with a positive controled airport for my safety and others, 3) I knew greensboro was an arsa which meant that if I transmitted 7700 emergency code I would be idented and they would clear me to land, which they did. 4) during the past 4 yrs I have had all of my maintenance performed at the greensboro airport and they would be best set up to remedy my problems. 5) my fuel supply was adequate for landing in the greensboro area (I had flown 3 hours 15 mins giving me a 45 min reserve for landing).
