Narrative:

All attempts to contact ground and tower to taxi and prior to takeoff failed until last transmission on tower frequency. Once tower replied to communications operation, returned to normal. Note: tower hours not continuous and recent frequency change. Suspect radio problem for that frequency or communications poor. Callback conversation with reporter revealed the following: ramp and runway area practically together at this small airport. Taxi distance very minimal. Reporter felt perhaps position was in area of some interference, moved aircraft and made contact with tower. Radios are of type with standby frequency position and occasionally seem to have problems.

Title: RADIO COM PROBLEM.

Narrative: ALL ATTEMPTS TO CONTACT GND AND TWR TO TAXI AND PRIOR TO TKOF FAILED UNTIL LAST XMISSION ON TWR FREQ. ONCE TWR REPLIED TO COMS OPERATION, RETURNED TO NORMAL. NOTE: TWR HRS NOT CONTINUOUS AND RECENT FREQ CHANGE. SUSPECT RADIO PROB FOR THAT FREQ OR COMS POOR. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: RAMP AND RWY AREA PRACTICALLY TOGETHER AT THIS SMALL ARPT. TAXI DISTANCE VERY MINIMAL. REPORTER FELT PERHAPS POSITION WAS IN AREA OF SOME INTERFERENCE, MOVED ACFT AND MADE CONTACT WITH TWR. RADIOS ARE OF TYPE WITH STANDBY FREQ POSITION AND OCCASIONALLY SEEM TO HAVE PROBLEMS.
