Narrative:

We monitored the CTAF for approximately 2-3 mins while taxiing and doing our preflight checks. We taxied to runway 25 at taxiway a. We visually checked for traffic and made the following radio call: 'aircraft X departing runway 25 at alpha straight out.' someone on the frequency said 'do you see me out here?' there was a person and a truck parked along the runway apparently working on something. I thought that this was the person who made the radio call. I made a radio call back; 'I'll get out of your way.' I started my takeoff roll and just as I was about to break ground; I heard another radio call; 'I'm on a 1 mi final for runway 7.' it was at this point that I realized that the first radio call was from someone in the air; not the person I saw on the ground. As I broke ground; I turned 30 degrees to the right and approximately 10 seconds later I saw a high wing aircraft approximately 1/2 mi in front of me and 500 ft above me in the opposite direction -- he was also turning to his right. Winds at the time of the occurrence were from 250 degrees at approximately 20-30 mph. The sun was low on the horizon which reduced my ability to see the aircraft and I thought at first the person talking on the radio was the person at the edge of the runway; not someone in the air. I also did not expect anyone to be making a downwind landing with a 20-30 mph tailwind.

Title: MISCOMMUNICATION RESULTS IN TWO ACFT ARRIVING AND DEPARTING IN OPPOSITE DIRECTIONS ON THE SAME RWY AT CTAF ARPT.

Narrative: WE MONITORED THE CTAF FOR APPROX 2-3 MINS WHILE TAXIING AND DOING OUR PREFLT CHKS. WE TAXIED TO RWY 25 AT TXWY A. WE VISUALLY CHKED FOR TFC AND MADE THE FOLLOWING RADIO CALL: 'ACFT X DEPARTING RWY 25 AT ALPHA STRAIGHT OUT.' SOMEONE ON THE FREQ SAID 'DO YOU SEE ME OUT HERE?' THERE WAS A PERSON AND A TRUCK PARKED ALONG THE RWY APPARENTLY WORKING ON SOMETHING. I THOUGHT THAT THIS WAS THE PERSON WHO MADE THE RADIO CALL. I MADE A RADIO CALL BACK; 'I'LL GET OUT OF YOUR WAY.' I STARTED MY TKOF ROLL AND JUST AS I WAS ABOUT TO BREAK GND; I HEARD ANOTHER RADIO CALL; 'I'M ON A 1 MI FINAL FOR RWY 7.' IT WAS AT THIS POINT THAT I REALIZED THAT THE FIRST RADIO CALL WAS FROM SOMEONE IN THE AIR; NOT THE PERSON I SAW ON THE GND. AS I BROKE GND; I TURNED 30 DEGS TO THE R AND APPROX 10 SECONDS LATER I SAW A HIGH WING ACFT APPROX 1/2 MI IN FRONT OF ME AND 500 FT ABOVE ME IN THE OPPOSITE DIRECTION -- HE WAS ALSO TURNING TO HIS R. WINDS AT THE TIME OF THE OCCURRENCE WERE FROM 250 DEGS AT APPROX 20-30 MPH. THE SUN WAS LOW ON THE HORIZON WHICH REDUCED MY ABILITY TO SEE THE ACFT AND I THOUGHT AT FIRST THE PERSON TALKING ON THE RADIO WAS THE PERSON AT THE EDGE OF THE RWY; NOT SOMEONE IN THE AIR. I ALSO DID NOT EXPECT ANYONE TO BE MAKING A DOWNWIND LNDG WITH A 20-30 MPH TAILWIND.
