Narrative:

Transiting approx 3-4 miles east of the airport on a north to south track and descending through 3700 ft MSL a single engine low wing aircraft (aircraft Y); on an east to west heading to the airport; passed within 300 ft of the helicopter. I had made two advisory position reports and was queried on one call by another aircraft as to my altitude. Aircraft Y was proceeding to the airport; while I was proceeding to the hospital; which is south of the airport. The aircraft Y made no position or advisory calls and by his lack of maneuver or radio call was probably unaware of this close call. No evasive maneuver was made by me since I ultimately saw him in front of the helicopter and opening the distance. Aircraft Y eventually made a 'entering downwind to runway 01' call and no other call was heard. Airport elevation is approx 2000 ft MSL and the airport is unicom. Single pilot seat in the helicopter is the right seat. From my position; this was a left to right encounter.
