Skywarn / ARES Usage

The W8DVH Owosso repeater is used for Skywarn in the local area. Every Moday at 7:00 PM (local time) a 'Skywarn Net' meets on the 147.020 (100 Hz) MHz analog system. Please make sure you listen a moment before using the repeater. Also, other areas use the C4 system for reflector 24 system.

Non-Specific Local Repeater Information

NOTE: The Owosso Repeaters have had digital voice capabilities since June, 2016. Some have internet gateway connection capabilities ~ Get on and say "Hey World - welcome to the Owosso area !"

There is an 'analog'/C4 Fusion digital system [N8DVH] and a D-Star [W8SHI] system in the Owosso area. Both are 'open' repeaters - so visitors are welcome.

N8DVH/W8SHI 2M (144 MHz) and 70cm (440 MHz FM) ~ Owosso Repeater Information

Owosso area analog voice repeaters (N8DVH/W8SHI) operate on 2 meters and 440 MHz. The Owosso Area repeaters operate:

  • 147.020 Mhz plus offset - Owosso (N8DVH) (100.0 PL tone required). C4FM/WIRES-X Gateway
  • 442.400 MHz plus offset - Owosso (N8DVH) (100.0 PL tone required)

    Both of these frequencies now operate with new Yeasu DR-1 C4FM/FM Digital repeater units (see below).

  • 145.240 MHz minus offset - Owosso (W8SHI) D-Star (Gateway)
  • 444.300 MHz plus offset - Owosso (W8SHI) D-Star

Al Langdon, N8DVH, is the repeater owner and is responsible for installation, maintenance, and operation of the local repeater network (N8DVH). The N8DVH Repeater System (Yaesu - C4FM Fusion & WIRES-X) uses a 100 hz (PL) tone on the repeaters and the system is open to any properly licensed amateur radio operator. The local Ham Community owes a 'huge' "Thank You!" to Al for his many years of support in the supplying and operation of the local repeater system.

Al also maintains W8SHI, the D-Star repeater for the Shiawassee county area. Al owns the equipment that supports the system. The repeater hardware box is owned by the Emergency Management, District 1, Michigan Section. That system has it's own web page... W8SHI.net home page.

The 2 meter Fusion unit [N8DVH] is operating on 147.020 MHz +0.600 MHz offset. The Yaesu repeater (C4FM) is operating at 20 watts, with an internet gateway and has WIRES-X capabilty (installed June, 2016). The duplexer is a TX RX Systems 28-27-02A. The feedline on the system is Andrew's heliax. All antennas are Diamond and mounted on the towere at 80 feet, making it about 96 feet to the top of the antenna.

The UHF unit operates on 442.400 MHz +5.0 MHz offset and has Yaesu (C4FM) repeater running 20 watts (installed June, 2016). The duplexer is a TX RX Systems 28-66-02A-2. The feedline on this system is Andrew's heliax as well. Again, the antenna is a Diamond and mounted at the 80 foot level on the tower.

HINT: For C4FM / WIRES-X search the Yaesu WIRES-X Node List to find your local active WIRES-X nodes. Use your browser search page function to locate the node ID and DTMF ID for your local city/system.

N8DVH/R1 WIRES-X uses N8DVH-RPT and DTMF 18453 for the 147.02 MHZ (+0.600 MHz) gateway system.

See the Yaesu WIRES-X site for further information: Yaesu WIRES-X home site. Some additional WIRES local information is:

=============

W8SHI Web Site

The W8SHI D-Star Repeater System (Icom) has its own Website at W8SHI Home , check it out for more detailed information. W8SHI is a "Gateway System", thus allowing you to talk to the world through equipped D-Star digital repeaters. The W8SHI Module C Repeater (145.240 MHz) is usually linked to Reflector 24 Module C, except for when the net meets on Mondays, when it is linked to module A. The Module B Repeater (444.300 MHz) is currently linked to Reflector 24 B which is being used by the Indiana D-Star group. Users such as mobile stations traveling through the area may unlink a repeater if it is not in use and relink it to another reflector of their choice. When the repeater is unlinked it will be automatically re-linked to the original reflector modules after a short time.

=============

Al Langdon, N8DVH, would like to thank the following list for their continued support of the Owosso Repeaters.

  • Shiawassee Amateur Radio Associatoion [S.A.R.A] ~ our local club.
  • Tom Carpenter, KI8AS
  • Mike Rothe, AB8VS

Other Repeaters in the Local Area

A nice map site (available by state) for repeaters is at Repeater Maps by state. You will need to select the search criteria for what you are looking for.

Check the Michigan Area Repeater Council for the Shiawassee County data at: http://www.miarc.com/repeater_directory.html, select the county of interest

Other amateur repeaters currently used in the local area:

  • 145.29 minus offset - Bancroft/Durand (N8IES) Analog and P25. Thanks to Tom Oliver, N8IES.
  • 145.39 minus offset - Okemos (WB8CQM) - RACES Affiliated
  • 146.78 MHz minus offset - Fenton {KB8AUX ~ FAARA} - w/autopatch
  • 146.94 Mhz minus offset - Lansing (WB8CQM) - w/autopatch, RACES Affiliated
  • 147.24 MHz plus offset - Saginaw (K8DAC ~ SVARA) - w/autopatch, RACES Affiliated
  • 147.26 plus offset (100 Hz)- Flint (Primary KF8UI)- w/autopatch, GC ARES / MSCG / MARET
  • 147.10 plus offset (100 Hz)- Flint (Secondary KF8UI)- w/autopatch, GC ARES / MSCG / MARET

   NOTE: Bancroft, Byron, Durand & Owosso have systems in Shiawassee County. Note from N8IES (7/10/2017): 145.290 is now combination analog/P25. We used the 33cm feedline and standoff for the new dmr repeater - so there is no 33cm p25 at this time (2018). 442.625 (N8IES) is back up.

Long Tone Zero [LiTZ]

A procedure to use a DTMF 'long tone zero' {5 seconds} at begining of a transmission and then asking for needed assistance. This is 'NOT' a CQ or ragchew procedure just when someone needs assistance from a fellow amateur radio operator. It is a Touch-Tone based all-call priority alerting system to be used on 'any channel' for requesting mutual assistance. Use LiTZ only when your normal voice calls go unanswered or people responding can not help you.

For further information refer to QST (Oct 1992, page 82; Nov 1992, pages 108-110; Dec 1995, pages 25-31) [information and decoders].

Wilderness Protocol

A suggestion for those outside normal repeater ranges should monitor standard simplex channels {primary is 146.52 MHz} for priority traffic. The protocol suggests stations should monitor primary and secondary frequencies, if possible, every three hours starting at 7:00 AM local time for a 5 minute period ~ 7:00 AM; 10:00 AM; 1:00 PM; 4:00 PM; repeating till 10:00 PM. If possible monitor every hour at the top of the hour. Secondary frequencies to consider: 52.525 MHz; 223.5 MHz; 446.0 MHz; & 1294.5 MHz. Use the Long Tone Zero protocal forr assistance needed calls. Hold CQ and normal transmissions until four minutes after the hour start. Refer to QST (Feb 94; page 100; Apr 1994; page 109; May 1994, pages 103-104) for further information.
