N6NA Repeaters
New N6NA Emergency Backup 2 meter Repeater
River City ARCS has a new emergency backup for our N6NA repeater on 145.250 MHz with the following settings:
Output Frequency: 145.250 MHz
Input Frequency: 144.650 MHz
Offset: Negative (-600 kHz)
Location: West side of Sacramento Valley near Zamora
PL/CTCSS: 123.0 Hz (set your receiver to carrier squelch, not tone decode)
Our regular repeater users should now program a separate memory in their radios with the same frequencies as our primary repeater, but with the 123.0 Hz PL tone and carrier squelch (no tone decode) for the backup repeater.
Our N6NA backup is a stand-alone repeater with no remote receivers or AllStar/EchoLink access. Our control operators will activate it only when our primary repeater is offline for periodic practice nets or due to equipment failure or power outage.
Program your radios now and be ready for future practice nets and emergencies!

N6NA 145.25 MHz FM Repeater Coverage Map
Legend:
Green - Mobile coverage with good antenna
Yellow - Base station range with outdoor gain antenna
Handheld radio coverage will vary with power, antenna and location
This N6NA 2 meter repeater transmitter coverage map shows estimated field strengths to an isotropic antenna 10 feet above ground based on the N6NA repeater 800 watt effective radiated transmitter power, 2000' ASL antenna elevation and terrain topography.
The 145.25 MHz repeater transmitter is located east of Sacramento in the foothills near Shingle Springs at about 2,000 feet. Our 800 watt effective radiated power system is designed to provide wide area coverage to the greater Sacramento area including Woodland, Davis, Elk Grove and beyond. This repeater's coverage typically extends into the Sacramento and San Joaquin Valleys past Chico, CA to the north, past Modesto, CA to the south and to the west past Concord, CA. Your range will vary depending on your radio and antenna.
In emergencies, the N6NA 145.25 MHz repeater system is the designated Tactical and/or Resource Net Frequency for the Sacramento Amateur Radio Communications Reserve (ARES/RACES).
The 2 meter system uses several remote receivers located around the Sacramento area that are connected to a "voter" which selects the best signal and sends it to the repeater transmitter. This facilitates repeater access with weak signals such as from low power handheld radios.
