Frequency-Plan

Frequency Plan

 
 

Net Control frequencies:

We have been asked to use 145.370- 107.2 as our primary frequency in lieu of 440.450 in view of the Air Force/FCC restrictions on the use of 70cm in the Bay Area.
 
Relays and mobile ham units will communicate with Net Control on the preceding frequencies. Mobile units will use these frequencies when the units are within range of Net Control.
Relay and SAG Wagon frequencies:
Routes Primary Secondary
120K Relay 1 147.555 s114.8
146.865 -114.8
75K, 50K, & 25K 145.370 -107.2
440.450 +107.2
  
Relays and SAG wagons will use the preceding frequencies to communicate with each other when the SAGs are out of range of Net Control.
Relays:
 
    * Relay 1 - Alpine road below Skyline (N37 18.032' - W122 12.341') Thomas Guide Map # 850, grid E1 at F1. [See map.]
    * Relay 2 - 1400 Native Sons of the Golden West Road (N37 24.041' - W122 20.535') Thomas Guide Map # 808, grid F3 (Map 808 is on the same page as Map 788, but is on the lower half of the page) where Native Sons of the Golden West intersects with Duncan Rd (which is also called Durham Rd on some maps). [See map.] [See directions.] [See photos.]
 
Each Relay will operate on the dedicated simplex frequency noted in the "Relay and SAG Wagon" table and will also have a second radio that will be capable of reaching Net Control via the repeater. The dedicated frequency is noted in the preceding table for each of the three Relays. Motorcycles and SAG wagons on those courses with ham radios will use those frequencies to communicate with Relay, and Relay will relay the messages to Net Control via the repeaters.
 
In the rare chance that a Relay location has a radio failure, they will let those on the course know they must leave the frequency for a few minutes to handle traffic on another frequency. If a station calls a relay location which doesn’t respond immediately, wait a few minutes to respond before trying something else. If relay still doesn’t respond after a delay, try another relay location to see if they can hear you. In many places on the course, more than one Relay location will hear you if you are on their frequency.
 

Motor Net: 

Motorcycles will communicate on Motor Net using CB Channel 1 as the primary frequency and CB Channel 2 as the secondary. Motorcycle units needing to communicate with Net Control will have their traffic relayed at Rest Stops or Relays as the case may be. Rest Stops and Relays may have CB radios.
Talk-in frequency:
 
Talk-ins will use 147.480 (simplex, no tone) to communicate with Net control.
