Radio in the Park

Cell service is strong in Estes Park and fades fast inside Rocky Mountain National Park. Radios fill that gap. This page collects the radio information that matters here: weather radio for warnings, the town's ham radio repeaters, family radios for groups, and the park channels that scanner listeners follow.

Listening never needs a license. Transmitting on the ham and GMRS frequencies does.

Weather radio: warnings when phones cannot reach you

NOAA Weather Radio broadcasts National Weather Service warnings, watches and forecasts around the clock. For this area:

• 162.450 MHz — the Fort Collins transmitter (call sign WXM92) carries Larimer County warnings.
• 162.475 MHz — the Mead and Longmont transmitter (WXM51) covers the south end of the county.
• Set the SAME county code to 008069 so the radio alerts only for Larimer County.

Mountain terrain blocks these VHF signals in places, so try both frequencies and keep the radio near a window. Reception is not guaranteed in the park's deeper valleys. A weather radio with a tone alert earns its keep overnight, when flash flood and fire weather warnings matter most and phones are off or out of coverage.

Ham radio repeaters in Estes Park

The Estes Valley Amateur Radio Club runs the town's repeaters under the call sign N0FH. They are open to any licensed amateur.

Frequency	Offset and tone	Notes
146.685 MHz	Minus offset, tone 123.0	The main 2 meter repeater. EchoLink node 625757 and AllStar. Emergency power.
449.800 MHz	Minus offset, tone 123.0	The UHF companion, linked full time to 146.685.
447.675 MHz	Minus offset, tone 103.5	Prospect Mountain. Part of the SkyHubLink statewide network.
147.240 MHz	Plus offset	DMR digital repeater, call sign N0WAR.

The ARES District 10 emergency net meets on the N0FH repeaters on Thursdays at 7 PM. For direct radio to radio talk with no repeater, 146.520 MHz is the national 2 meter calling frequency.

Coming in from the east side, the Northern Colorado club's machines also reach toward the park: Horsetooth Mountain on 145.115 MHz (tone 100.0) and Buckhorn Mountain on 146.625 MHz (tone 100.0), call sign W0UPS.

Family radios: FRS and GMRS

FRS radios, the kind sold in pairs at any outdoor store, cover channels 1 to 22 with no license at all. They are the practical choice for a group spreading out on a trail, a campground or a festival crowd in a valley with no cell service.

GMRS uses the same channels at higher power and adds repeater channels. It takes an FCC license: $35 for 10 years, and one license covers your immediate family.

Pick your channel and privacy code before the group splits up, and test it in the parking lot. No FRS or GMRS channel is monitored for emergencies. In an emergency, call 911 where you have service, or use a satellite messenger where you do not.

Listening to the park

Rocky Mountain National Park runs its radio traffic on the East Net and the West Net. The repeater outputs are public and legal to listen to:

Frequency	Repeater site	Net
169.800 MHz	Prospect Mountain	East
171.750 MHz	Twin Sisters	East
171.025 MHz	Alpine Visitor Center	East
170.3875 MHz	Meadow Mountain	East
172.750 MHz	Red Mountain	West

Traffic runs in both analog and digital (P25), so a basic analog scanner hears only part of it.

Repeaters go on and off the air, so confirm a repeater before you count on it. Estes Park Tour Guides does not operate any of these systems.
