Narrative:
I was on a pleasure flight with a glider student of mine. We took off on runway 20 with calm winds. Runway 20 was previously used. We flew approximately 45 mins in the local area. Returning to the airport, I elected to land on runway 2 because it is the normal runway when winds are calm. I made several position announcements during the approach. No other aircraft were observed or heard on my radio. As I flared and touched down, I saw the other aircraft (C172) coming towards me. As I was braking, I could not determine if the C172 was landing or taking off. I decided to abort my landing. I turned off the runway and took off on the grass, to the right of the C172. We flew over and beside the C172, I left the pattern and returned for a normal landing on runway 20. I found out afterwards that my portable radio's battery had failed. My portable intercom still functioned, misleading into thinking my radio was functioning because of backgnd. Based on the knowledge I had at the time, it felt my evasive actions were correct. In the future, I need to check my portable radio to assure myself it is functioning. The C172 blended into backgnd because of color and overcast providing little contrast.

Title: BL65 PLT INVOLVED IN NMAC WITH A C172 AT PLR ARPT CAUSED IN PARTIAL TO A FAILED PORTABLE INTERCOM RADIO.
Narrative: I WAS ON A PLEASURE FLT WITH A GLIDER STUDENT OF MINE. WE TOOK OFF ON RWY 20 WITH CALM WINDS. RWY 20 WAS PREVIOUSLY USED. WE FLEW APPROX 45 MINS IN THE LCL AREA. RETURNING TO THE ARPT, I ELECTED TO LAND ON RWY 2 BECAUSE IT IS THE NORMAL RWY WHEN WINDS ARE CALM. I MADE SEVERAL POS ANNOUNCEMENTS DURING THE APCH. NO OTHER ACFT WERE OBSERVED OR HEARD ON MY RADIO. AS I FLARED AND TOUCHED DOWN, I SAW THE OTHER ACFT (C172) COMING TOWARDS ME. AS I WAS BRAKING, I COULD NOT DETERMINE IF THE C172 WAS LNDG OR TAKING OFF. I DECIDED TO ABORT MY LNDG. I TURNED OFF THE RWY AND TOOK OFF ON THE GRASS, TO THE R OF THE C172. WE FLEW OVER AND BESIDE THE C172, I LEFT THE PATTERN AND RETURNED FOR A NORMAL LNDG ON RWY 20. I FOUND OUT AFTERWARDS THAT MY PORTABLE RADIO'S BATTERY HAD FAILED. MY PORTABLE INTERCOM STILL FUNCTIONED, MISLEADING INTO THINKING MY RADIO WAS FUNCTIONING BECAUSE OF BACKGND. BASED ON THE KNOWLEDGE I HAD AT THE TIME, IT FELT MY EVASIVE ACTIONS WERE CORRECT. IN THE FUTURE, I NEED TO CHK MY PORTABLE RADIO TO ASSURE MYSELF IT IS FUNCTIONING. THE C172 BLENDED INTO BACKGND BECAUSE OF COLOR AND OVCST PROVIDING LITTLE CONTRAST.
