Narrative:

As I taxied out, the wind sock was limp but facing east and I chose runway 6. My calls to unicom on 122.7 were not answered. After run-up, I announced my intentions to take runway 6 for takeoff and depart east. I looked for aircraft, saw none, and began my takeoff. At liftoff, I saw another aircraft approaching from the opposite end of runway. I turned right early and the approaching jet turned off on a taxiway. While I don't think the aircraft were ever closer than 1000 ft, it was a disconcerting experience. After becoming airborne, initial calls to ZDV were not answered. I received a call on 121.5 asking about my problem. I have a switch which activates 121.5 and overrides any frequencys set in the communication radios. This switch was on. I assume that I was not transmitting or receiving on the 122.7 set in the radio. My takeoff position (touchdown zone runway 6000-7660 ft) was 13 ft below the listed elevation of the 9402 ft runway resulting in a problem seeing the other aircraft on the other end of the runway. Obviously not being on the CTAF frequency contributed significantly to the problem.

Title: PLT OF A PIPER CHEYENNE, PAYE, NOTICED A JET TYPE ACFT ROLLING OUT AND TURNING OFF THE RWY FROM THE OPPOSITE DIRECTION DURING TKOF AT A NON TWR ARPT.

Narrative: AS I TAXIED OUT, THE WIND SOCK WAS LIMP BUT FACING E AND I CHOSE RWY 6. MY CALLS TO UNICOM ON 122.7 WERE NOT ANSWERED. AFTER RUN-UP, I ANNOUNCED MY INTENTIONS TO TAKE RWY 6 FOR TKOF AND DEPART E. I LOOKED FOR ACFT, SAW NONE, AND BEGAN MY TKOF. AT LIFTOFF, I SAW ANOTHER ACFT APCHING FROM THE OPPOSITE END OF RWY. I TURNED R EARLY AND THE APCHING JET TURNED OFF ON A TXWY. WHILE I DON'T THINK THE ACFT WERE EVER CLOSER THAN 1000 FT, IT WAS A DISCONCERTING EXPERIENCE. AFTER BECOMING AIRBORNE, INITIAL CALLS TO ZDV WERE NOT ANSWERED. I RECEIVED A CALL ON 121.5 ASKING ABOUT MY PROB. I HAVE A SWITCH WHICH ACTIVATES 121.5 AND OVERRIDES ANY FREQS SET IN THE COM RADIOS. THIS SWITCH WAS ON. I ASSUME THAT I WAS NOT XMITTING OR RECEIVING ON THE 122.7 SET IN THE RADIO. MY TKOF POS (TOUCHDOWN ZONE RWY 6000-7660 FT) WAS 13 FT BELOW THE LISTED ELEVATION OF THE 9402 FT RWY RESULTING IN A PROB SEEING THE OTHER ACFT ON THE OTHER END OF THE RWY. OBVIOUSLY NOT BEING ON THE CTAF FREQ CONTRIBUTED SIGNIFICANTLY TO THE PROB.
