Other Mono County repeater PL tones. 146.2 is for Leviathan, 114.8 for Antelope Mountain northwest of Benton, 127.3 for June Mountain, 151.4 for Lincoln Mtn. (actually not on Lincoln now, which is a peak near Mammoth Mountain, but on Casa Ridge just east of the old Mono 2) and 131.8 for Casa Diablo Peak, located southeast of Crowley Lake. It is the forested hill you can see to your northeast as you drive northbound on 395 up Sherwin Grade. There is also a repeater located at the Crowley Lake fire station using 123.0. This repeater is only on "County Fire" or 153.860. All the other repeater locations have both the S.O. on 154.800 and County Fire. Another frequency recently added by Mono County is their tactical simplex of 158.880. The old Benton repeater was located in the fire station there and I believe it was relocated to Antelope Mountain. I have not verified this yet.
EMS (154.025) just has Sweetwater, Conway, and Casa Diablo and the tones are the same. In the Mammoth area simplex is used as the Mammoth Hospital is the answering point for all ambulance to hospital traffic in the county. 154.025 is only used for ambulance to hospital and the county fire net is used to dispatch them. Another net is the county admin/public works system on 153.920. They have repeaters at the same locations as EMS, but the output tone is common for all the repeaters. 118.8 for public works and 103.5 for admin. The input tones are pretty complex as each repeater has two different input tones depending on the use (admin or public works) of the radio. Cell phones have reduced the admin traffic to almost nothing.
About 18 months ago Mammoth PD left the sheriff's net and put their own repeater into use for dispatching. Mono 1 is still the dispatching point for them. 155.595 used to be a simplex tactical for the department, but a new frequency was obtained and a repeater was placed up on the upper gondola station at the top of Mammoth Mountain. So far I haven't found them using a tactical frequency.
The last net for Mono County is for the Eastern Sierra Unified School District and is located on Conway Summit on 153.980 with a PL of 146.2.
One of these days I will submit all the info I have for Mono County on the RR database. What is there now is only partial information.
