Silicon Valley Tour de Cure 2010

Frequency Plan
(No change from 2009)

(Last revision: 2010-06-10)

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.

Routes	Primary	Secondary
120K	146.865 -114.8	145.370 -107.2
75K, 50K, & 25K	145.370 -107.2	440.450 +107.2

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
120K Relay 2	147.585 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. We are NOT staffing Relay 2 this year.

Relays:

Relay 1 - Alpine road below Skyline (N37 18.032' - W122 12.341') Thomas Guide Map # 850, grid E1 at F1. [See map.][See photos.]
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). Also, please note, there will probably be bikes on Kings Mountain Rd that morning. An alternate route would be to go Sand Hill to La Honda Rd and then right onto Skyline[See map.] [See directions.]

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.

SAGs & Motor Units:

SAGs and Motorcycles will communicate using the appropriate Net (120K or 25K/50K/75K) for the route they are covering. If they are unable to reach Net Control using that frequency, they should try the Relay 1 simplex frequency (147.555 s114.8). If they are unable to reach Relay on that frequency, change locations and try again.

Talk-in frequency:

Talk-ins to Start / Finish area will use 147.480 (simplex, no tone) to communicate with Net control. In addition, the Emergency / Net Control phone (650-391-5057) will be on starting ~0530.
