Hams for Emergency Radio Communications (HERC)

The HERC system has essentially dissolved and no longer exists

The HERC system was a network of interlinked repeaters across the state of Wyoming. As well as being a valued emergency resources, HERC was a great way for travelers or folks living in different communities to keep in touch. A weekly traffic net was held on Sunday evenings.

Since the demise of HERC, a new linked system called WyoComm has grown to include several areas in Wyoming. See the WyoComm page for details.

Sites

Many of the individual sites and their repeaters used in HERC remain and most are now used locally.

Currently the .940 in Rock Springs, the .820 in Cheyenne/Laramie, and the .390 Rawlins repeaters all exist. The Rock Springs and Cheyenne/Laramie repeaters are stand alone machines that both have great coverage of their respective parts of I-80 and surrounding roads.

The Rawlins .390 repeater has been linked into the WyoComm system.

Thank you!

Many thanks to Larry Hudson, KD7BN and those that built HERC and kept it running for so long!

A History

Provided by Paul, KB7FGN, an email describing the setup and development of the old HERC system (Feb 2015)

The original HERC system never did link over Togwotee pass, towards Jackson. It only linked to 146.820- w/100htz. tone at Windy Ridge @ Dubois. That is still present, although it is off line to the link at this present time. All I have to do is call WB7FIU-Ed, and he will bring it up.

The original Limestone link (I think was 220 mhz) was into 146.670- into Rock Springs.

There was also a 146.670- repeater on top of Shell Canyon, that came in to Copper Mtn. via 440 mhz. That machine has long been defunct.

Casper used to only be 147.460 simplex, and it was 220 mhz to Pine Hill, and 440 mhz from there to Sherman Hill, and 440 mhz to the original 147.030 on Boysen Peak.

Then, a lot later in the history of the HERC system, there was a 146.985- w/100 htz tone on Pumpkin Butte, that was 440 mhz linked into the .460 machine on Casper Mtn. At one time, Jay Ostrem had a 147.580 simplex at his house, west of Gilette, that linked via 440 mhz to Pumpkin Butte, and then Casper Mtn.

There was even a simplex input clear out to Manville, at one point in time, that covered I-25 from east of Glenrock, down around Orin Junction, and then some, but, it was a pretty short lived machine.

Some of this was run with 147.030+ repeater, when it was on Boysen Peak, but, later on, the 146.805- came into play on Copper Mtn., as .030 had problems and access to Boysen Peak became a major obstacle. At any rate, slow, but sure, everything kind of went to pot, and there wasn’t much support from the outlying machines, and it all kind of mutated to the existing system, 146.805- w/440 mhz link to Casper, and to 147.390+ on 9 mile hill @ Rawlins, and to avoid confusion, was re-named Wyo Comm system.

I know all these things, because I have been very good friends with KD7BN-Larry and N7EMI-Merlene, every since I got my Tech license in Sept. 1988, and talked to them every trip to Lander, every summer. This was about the same time that Larry was getting things working for the HERC system, and every summer trip to Lander, it always had some more capabilities.Then, when I moved to Glenrock in 1990, I went to Pumpkin Buttes w/W7PAW-Lew a few trips to make 146.985- work, and out to Manville one trip, with him.

Not providing this to be a smarty aleck or anything, but, this is a pretty good run down on how it used to be.

Thanks, KB7FGN-Paul
