Great Basin National Park Freqs.

The Frequencies For The Great Basin National Park Are Also Missing.
The Only 2 Frequencies I Have Was When It Was Called Lehman Caves.
163.150 Mhz And 164.800 Mhz Shannon

The most current information I have (2007) shows 164.800 being used simplex, but this listing was in the Great Basin Aviation Communications Plan. Aircraft very often talk simplex only on small units such as Great Basin National Park. I do have an official listing from 1997 that shows 164.800 as output and 163.150 as input. The repeater site shown is Notch Peak with a PL of 127.3. Notch Peak is located north of U.S. 6 about 40 miles northeast of the park in Utah.

Its been 17 years since I stopped there and it was a quick overnight in mid October. We arrived in the late afternoon and left early the next morning on our way to Idaho and Montana on a planned two week camping trip. We ended up "camping" in motels more than in campgrounds as the weather was very cold and rainy. We didn't pick up anything on 164.800. About 8 years prior to that, before I had widespread frequency information for natural resource agencies, I stayed there for two nights, when the National Park Service only managed the much smaller Lehman National Monument, and the surrounding land was part of the Humboldt National Forest. This was earlier, just before Labor Day weekend. Being it was so small the National Monument frequency proved elusive when I tried limit searches.

The Park was designated by the Congress in 1986, incorporating over 77,000 acres of the Humboldt National Forest and the small Lehman Caves National Monument. There should be more radio traffic as a result, but it still isn't a heavily used park, with just over 82,000 visitors in 2007. The highest peak in the park, Mt. Wheeler, at 13,063 feet the highest peak in the Snake Range and second highest point in Nevada, has a small glacier on its north side, the only one in the state. There are some backpack trips I would like to take in Great Basin NP as well as over in the Ruby Mtns. Both ranges have glaciated terrain, lakes, very dark night skies, and wonderful remoteness.

I just found some old printed information that came from a website called "Cape Canaveral," believe it or not. It shows the repeater to be in King Canyon, a name I can't find on my nationwide topo software, with 164.800 out/163.150 in and 127.3 as the PL. A call sign of KOJ764 is listed. The source of this information is shown as only "DOI '95." It also states "separate VHF system for inside Lehman. Antenna system inside the cave. Ranger described as separate channel on the radios for inside the cave." It goes on to say that a separate list that showed Lehman Caves only has 171.750, 172.450, and 172.675 on it.

If my wife and I get jobs and can stay in Mammoth or the eastern Sierra, maybe we should make a trip over there and figure this thing out. Let's see, right now we have the time but no money, and if we get our wish, we will have money and no time. One of the greatest dilemmas of life!

The Last Time I Was There (1991) I Also Heard The Humboldt National Forest
Repeater 171.475 Mhz From There (i Dont Know The Input Frequency) Also
Blm Cedar City Utah And Ely Nevada Repeaters Shannon

Up until 3-5 years ago the Humboldt National Forest did not use CTCSS to select repeaters. Field units accessed repeaters by switching to channel 2. If they were in a location where the coverage of two or more repeaters overlapped then "repeater wars" would result. When the dispatcher used repeaters the result would be the same. Typically this occurred when dispatch read the weather or made an announcement. When I first arrived on the Toiyabe National Forest in 1981 (the Humboldt and Toiyabe were separate forests) the radio system was set up the same way.

In 1987 and 1988 the Toiyabe replaced the ancient radio system with one that consists of a microwave backbone, UHF links to repeaters, and tone accessed repeaters. A portion of the microwave backbone is Forest Service built and owned, and a portion utilizes the State of Nevada microwave system.

As far as I know the Humboldt NF now ties in with the state's microwave system. They must have replaced their system and added tone accessed repeaters about the same time. Somewhere I have information about the repeaters and their tones. One of these decades I will take the time to submit this information for the database.
