C180 TAXIES TO RWY 30 FOR DEP; MONITORING AWOS; FAILED TO HEAR GLIDER TOW DEPARTING RWY 25. CROSSED RWY 25 ON TXWY JUST AS THE GLIDER WAS IN THE AIR AND MISSED BY 10 FT. GLIDERS WERE ON A DIFFERENT AIR-GND FREQ.

Narrative

WHEN TAXIING FOR TKOF ON RWY 30 PARALLEL TXWY; I WAS GUARDING 123.0 (UNICOM) WHILE LISTENING TO THE 'PANGBORN AUTOMATED' WX. (THE ANNOUNCEMENT: 'PANGBORN MEMORIAL ARPT' IS LOUDLY ANNOUNCED; FOLLOWED BY A DIFFERENT; PROBABLY SYNTHESIZED VOICE WITH THE WX; BUT THE 'PANGBORN' ANNOUNCEMENT BLEEDS OVER SUCH THAT YOU HEAR 2 VOICES.) THIS MAY HAVE CONTRIBUTED TO MY MISSING A TKOF CALL (PROBABLY BY THE GLIDER TUG IF AT ALL) OF A GLIDER TOW ON RWY 25. AS A RESULT; I TAXIED IN FRONT OF AND UNDERNEATH A GLIDER IN TOW. NEITHER OF US IN THE C180 SAW ANYTHING; EVER. ALTHOUGH THE APCH END OF RWY 25 IS NOT VISIBLE FROM THE DEP END OF RWY 30 OR WITHIN ABOUT 200 FT OF WHERE RWY 25 CROSSES RWY 30 PARALLEL TXWY; I SHOULD HAVE BEEN MORE ALERT. I WAS TOLD LATER THE GLIDER APPEARED TO CROSS OVER ME WITH '10 FT OF CLRNC.' AFTER MY RUNUP AND AT BEGINNING OF MY TKOF ROLL; A RELATIVELY CALM VOICE GRUMBLED AT 'THE TAILDRAGGER' WHICH 'CAUSED A PWRED PLANE TO ABORT TKOF ON RWY 25.' THIS PUZZLED US AT THE TIME; FOR WE NEVER SAW GLIDER OR TUG; DURING TKOF OR ON DOWNWIND. THE GLIDERS WERE USING A DIFFERENT FREQ FOR AIR-GND; SO THIS MAY HAVE BEEN A FACTOR. I WAS AWARE OF OCCASIONAL GLIDER OPS. I THINK WARNING SIGNS WOULD HELP.
