The following frequency listings are those that have a possible potential for interference at our field location because of adjacent paging channels in the frequency band. However, major manufacturers have advised that a dual conversion receiver will not have problems with interference from such legally assigned adjacent frequency paging channels, if the radio in use has been properly tuned. UPDATE: The frequencies were scanned in mid 2001 and found the same interference as before. (During a three week November 1997 test, a scanner picked up paging signals only between those channels shown below): Channel Frequency Paging service User (if known) 11 72.010     72.020 U.C.S.D. Medical Center 12 72.030   ...     23 72.250     72.260 Kaiser Permanente (near Sports Arena) 24 72.270   ...     28 72.350     72.360 I.C.S. Paging 29 72.370   ...     36 72.510   ...     50 72.790   ... 72.800 Unknown 51 72.810   ...     54 72.870     72.880 Unknown 55 72.890   It is unknown which other channel should be paired with 36 [either 35 or 37]as the only activity heard was on channel 36... The scanner used was not selective enough to tell if the activity actually encroached on our assigned frequencies or was just above or below ours. We believe that properly tuned receivers should not have any interference problems. Further, there has been no identified interference observed at the field during recent years that ever resulted in flight curtailments.
