Narrative:
Mojave airport has non federal control tower between XA00-XB00 wkdays, otherwise uncontrolled. CTAF is 127.6, los angeles sectional, shows unicom 122.8. Approaching on apr/sat/95 I called 127.66, got no answer, then 122.8 no answer (lot of interference from apple valley on 122.8). I then landed, with blind calls to traffic (there was none) and then flew some nonstandard patterns simulating engine failures. Finally I did get a call on 122.8 advising me to use 127.6 for advisories, after I said I saw a departing aircraft. Why not remove 122.8 from the sectional chart and show 127.6 as CTAF? Potential exists for aircraft using different frequencys to not know about each other.

Title: FREQ PROB AT ARPT WITH NON FEDERAL CTL TWR AND LISTING CTAF ALONG WITH UNICOM FREQ.
Narrative: MOJAVE ARPT HAS NON FEDERAL CTL TWR BTWN XA00-XB00 WKDAYS, OTHERWISE UNCTLED. CTAF IS 127.6, LOS ANGELES SECTIONAL, SHOWS UNICOM 122.8. APCHING ON APR/SAT/95 I CALLED 127.66, GOT NO ANSWER, THEN 122.8 NO ANSWER (LOT OF INTERFERENCE FROM APPLE VALLEY ON 122.8). I THEN LANDED, WITH BLIND CALLS TO TFC (THERE WAS NONE) AND THEN FLEW SOME NONSTANDARD PATTERNS SIMULATING ENG FAILURES. FINALLY I DID GET A CALL ON 122.8 ADVISING ME TO USE 127.6 FOR ADVISORIES, AFTER I SAID I SAW A DEPARTING ACFT. WHY NOT REMOVE 122.8 FROM THE SECTIONAL CHART AND SHOW 127.6 AS CTAF? POTENTIAL EXISTS FOR ACFT USING DIFFERENT FREQS TO NOT KNOW ABOUT EACH OTHER.
