Private aircraft landed bjc and after circling the runway, contacted ground control on 121 pt 8. The trouble is, that is the frequency for another airport serving the same city. This other ground controller gave him taxi clearance which he accepted, thus taxiing without clearance.

Narrative:
Upon landing at bjc, took first turnoff and stopped short of parallel taxiway. Controller said contact ground on 121.8. I did that and asked for clearance to ramp (non controled area). Was given clearance to cross bjt, was told I was 'scratchy.' I confirmed clearance and proceeded into ramp area. Ground control was also noisy to use. After further thought I was given and used wrong ground frequency. 121.8 is ground control for apa across town many mi away. Would suggest a change of ground control frequencys in the denver area. Having 3 frequencys that are consecutive is prone to error. Currently using 121.7, 121.8, and 121.9 in this area.

WAS GIVEN CLRNC TO CROSS BJT, WAS TOLD I WAS 'SCRATCHY.' I CONFIRMED CLRNC AND PROCEEDED INTO RAMP AREA. GND CTL WAS ALSO NOISY TO USE. AFTER FURTHER THOUGHT I WAS GIVEN AND USED WRONG GND FREQ. 121.8 IS GND CTL FOR APA ACROSS TOWN MANY MI AWAY. WOULD SUGGEST A CHANGE OF GND CTL FREQS IN THE DENVER AREA. HAVING 3 FREQS THAT ARE CONSECUTIVE IS PRONE TO ERROR. CURRENTLY USING 121.7, 121.8, AND 121.9 IN THIS AREA.
