General Information About The N5FDL Repeaters

User rules:

1. The repeaters are open to all Radio Amateurs, but we reserve the right to bar specific individuals if necessary to maintain order, a friendly atmosphere and/or FCC rules compliance.

2. Emergency and public safety uses take precedence at all times. It is not necessary to get permission to use the repeaters for emergency or public service communications on an unscheduled basis. If you have a sudden need, please use the repeaters. If you know in advance that you need to use the repeater(s) for an event, please warn us so we know what to expect and when.

3. All repeaters are coordinated through the Northern Amateur Relay Council of California. David Coursey, N5FDL, is the coordination holder. Some of the equipment is owned by California Emergency Volunteers, Inc., a 501(c)(3) charitable organization.

4.All these repeaters tend to be quiet. Please use them.

Here are coverage estimates for each repeater. We hope to post coverage maps in the future.

147.210 — Located in northeast Stockton with the antenna side-mounted on the tower, coverage is not circular and seems to be shielded a bit toward to Delta.

In general, this repeater provides handie-talkie coverage over most of Stockton (please send reports of your experiences) and mobile coverage to an area bounded by someplace in the Delta to the west, Elk Grove to the north, the foothills to the east and Turlock to the south.

444.500 — We have not extensively drive-tested this repeater, but its coverage should approximate that of 147.210. The two repeaters are co-located and linked.

147.015 — Located west of Copperopolis, at 1600 feet, this repeater has 6db gain to the west, 3db north and south and -7.5db to the rear (which are the higher foothills). Tracy is 40 miles away, but there is some HT coverage there. Mobile coverage reaches into the Delta, but the site is shielded to the north so that Galt and Lodi are the northern edge. The southerly coverage is excellent and extends almost to Fresno on 99 and to 50 miles south of Highway 152 on I-5 (which benefits from a bit of elevation). This should be HT coverage for all of eastern San Joaquin and Stanislaus Counties.

146.895 — This Mt. Oso (3200-feet) repeater does not work well up close (like Tracy) because of the current antenna and somewhat deaf receiver. Other than that, it works well for mobile users from north of Stockton to at least Turlock. No courtesy tone and this repeater IDs every nine minutes. A replacement repeater and antenna awaits installation.

443.825 — Co-located with 146.895, this 1-watt repeater works shockingly well, especially in locations with few obstructions between you and Mt. Oso. We have used this repeater with a talkie from the steps of Lodi Memorial Hospital. The repeater is never very strong, but works well for what it is. Interference from a co-channel Fresno repeater has been eliminated (the Fresno machine moved almost to Bakersfield).

Tracy coverage — We will install a UHF repeater to provide HT coverage in Tracy. Once fixed, 146.895 may also provide this and 147.015 is an option in some parts of the city.
