Mount Bullion is located a few miles out of Mariposa. All repeaters and remote bases are controlled by one of the two RLC-DSP404 controllers. All repeaters and remote bases can be linked to any other analog equipment on Mt. Bullion.
147.03 MHz + (100Hz)
224.96 – (156.7Hz)
444.7 MHz + (94.8Hz)

These receivers act as cross band repeaters between 147.63 MHz and 449.7 MHz. All of these receivers are bi-directional meaning you can transmit into them on either 2 Meters or 440 except for Turlock. Both UHF and VHF PLs are the same for all of the receivers.
Turlock: 103.5 Hz
Los Banos: 107.2 Hz
Atwater: 114.8 Hz
Fresno: 118.8 Hz
In Turlock TARC has a VHF repeater, remote receiver, as well as a 2 Meter/440 remote base. Under normal circumstances the Turlock system is configured as a remote receiver. When it is configured this way it is only mono-directional, 2 Meters input only. The Turlock system can also be configured so that the remote base is being repeated through the UHF/VHF repeater on Mount Bullion. The frequency of the repeater/remote receiver is as follows:
Turlock: 147.03 MHz + (103.5Hz)
TARC has two repeaters in Yosemite National Park. Both repeaters are normally linked to the rest of the system via the 420 hub, but if necessary can be unlinked at anytime. Both repeaters have excellent coverage in and around the park.
TARC has a UHF repeater in Sequoia National Forest on Buck Rock near Kings Canyon National Park. The repeater is normally linked to the rest of the system via the 420 link but can be unlinked at any time.
TARC has four DMR repeaters. All four repeaters are tied to the brandmeister network on both timeslots.
Note: Local on all TARC DMR repeaters is linked through a cluster. When you talk on local on one of them it repeats on all of them.
Mount Bullion UHF: TX: 444.7875 – RX: 449.7875 – CC: 1
Mount Bullion VHF: TX: 144.9375 – RX: 147.4375 – CC: 1
Mount Oso: TX: 440.1875 – RX: 445.1875 – CC: 1
Turlock Low Level: TX: 444.350 – RX: 449.350 – CC: 2 – Network Down
All TARC DMR repeaters have the following static talkgroups.
NorCal: 31068 (Timeslot 1)
California: 3106 (Timeslot 1)
Local: 2 (Timeslot 2)
Except for local, all traffic should take place on timeslot 1.
Although all brandmeister talkgroups will work, TARC members have the following as a minimum:
NorCal 1: 31069
Cal 1: 31061
SoCal 1: 31067
Call Zone 6: 31096
North America: 93
TAC 310: 310
TAC 311: 311
TAC 312: 312
