Nets & Sirens


HPARC Sunday Night Two Meter Net

The Hazel Park Amateur Radio Club hosts a weekly FM voice net every Sunday at 9 PM ET. This net first started in 1968, when it began as an AM simplex net. Today, it is held on the DART VHF repeater (146.640 MHz, 100.0 Hz PL, negative offset), and can also be reached using the DART UHF repeater (443.225 MHz, 107.2 Hz PL, positive offset), Echolink (“W8HP-R” or node 980938), and IRLP (node 4520).

We welcome all licensed amateur radio operators from anywhere in the world; you do not have to be an HPARC member to participate, nor do you need to be located in or near Hazel Park. Some of our net regulars come from as far as Sydney, Australia and the Kingdom of Thailand!

Our net manager is Bob (N8REL), and the current net control operators are Lee (KD8TBC), John (W8TOY), and Mike (K8WU). For more information, please contact Bob.

Al’s Geezer Net

In addition, HPARC Field Day Chairman and MSPOTA Coordinator John (AA8UU) hosts a weekly 10 meter CW net every Tuesday at 8 PM ET on 28.028 MHz. The net is generally called at 15 WPM, but you may check in at whichever speed you are most comfortable sending. This is an informal net; feel free to listen and copy along.

There is an “afterglow” net after the CW net closes (usually by 8:20 PM or so) on the DART UHF repeater (443.225 MHz, 107.2 Hz PL, positive offset).

Other Area Nets

Additionally, there are other nets which are run by club members, friends of the club, and other clubs in the area:

  • Southfield Amateur Radio Service (SARS) Net – every Tuesday at 8:05 PM ET on the DART VHF repeater at 146.640- MHz 100.0 Hz PL (net manager: Jeff KA8PHP)
  • USECA 2 Meter Vertical Sideband Net – daily at 8:30 PM ET on 144.230 MHz USB (net managers: Chuck N8ZA and Leonard N8YBY)
  • Warren Double Nickel Local Repeater Net – every Monday at 7:00 PM ET on the KA8WYN repeater at 443.550+ MHz 107.2 Hz PL (net manager: Don WA8E)
  • Voice of the Great Lakes Radio Net – every Sunday at 7:00 PM ET on 28.430 MHz USB (net manager: Jim KE8NUL)


HPARC assists Oakland County to check the outdoor sirens and report their status. The SE Quadrant has 79 sirens to check each season. We also assist the other quadrants after we finish our area. The SE Quadrant is the area of Oakland County from 8 Mile Rd. on the south to South Blvd. on the north, and from Haggerty Rd. on the west to Dequindre Rd. on the east.

The Siren Test Net is held from 12:30 to 1:30 PM ET on the first Saturday of the month from March to November. NOTE: the April siren test is replaced with one on the first Wednesday of the month in conjunction with Severe Weather Awareness Week.

The DART VHF repeater (146.640 MHz, 100.0 Hz PL, negative offset) is our primary repeater. Our backup repeater – which we are currently using – is the WB8ARC UHF repeater (442.500 MHz, 107.2 Hz PL, positive offset).

Operators will use their own analog FM capable dual-band radio. If it is an HT, then at least a mag-mount antenna is usually needed. Volunteers will be assigned unchecked sirens throughout the area as deemed necessary. To volunteer or get more information, contact the Subnet Coordinator Marsha Fleming, N8FE, at n8fe nospam at arrl dot net (remove “nospam”).
