Narrative:
Cruise en route V-257 southbound from bryce canyon VORTAC I was advised by ZLA on IFR flight plan to climb to 15,000' MSL. I advised we couldn't comply for oxygen reasons. I cancelled IFR at kacir intersection. I experienced radio problems at this time, and couldn't continue contact with center. I decided to be VFR and transit grand canyon sfra through dragon corridor, following V-257 until I could intercept the page VORTAC 203 degree right. After descending to 10,500' MSL about 3-5 mi north of the north rim and loosing bryce canyon VOR signal and unable to receive grand canyon VOR, I attempted picking up 203 degree with wind correction. I then lost page VOR just crossing into the canyon. I hoped I was on course for the dragon corridor but honestly I wasn't sure.

Narrative: CRUISE ENRTE V-257 SBND FROM BRYCE CANYON VORTAC I WAS ADVISED BY ZLA ON IFR FLT PLAN TO CLIMB TO 15,000' MSL. I ADVISED WE COULDN'T COMPLY FOR OXYGEN REASONS. I CANCELLED IFR AT KACIR INTXN. I EXPERIENCED RADIO PROBLEMS AT THIS TIME, AND COULDN'T CONTINUE CONTACT WITH CENTER. I DECIDED TO BE VFR AND TRANSIT GRAND CANYON SFRA THROUGH DRAGON CORRIDOR, FOLLOWING V-257 UNTIL I COULD INTERCEPT THE PAGE VORTAC 203 DEG R. AFTER DESCENDING TO 10,500' MSL ABOUT 3-5 MI N OF THE N RIM AND LOOSING BRYCE CANYON VOR SIGNAL AND UNABLE TO RECEIVE GRAND CANYON VOR, I ATTEMPTED PICKING UP 203 DEG WITH WIND CORRECTION. I THEN LOST PAGE VOR JUST XING INTO THE CANYON. I HOPED I WAS ON COURSE FOR THE DRAGON CORRIDOR BUT HONESTLY I WASN'T SURE.
