Mount Rowe has an elevation 1,680 feet (510 m), and is a mountain located north of Gunstock Mountain . It is located in the Belknap Range, Belknap County, New Hampshire, It has been home to many ski resorts, including the original Gunstock Mountain Resort with a chairlift that has since been removed. The Belknap Ski Jumps and the defunct Alpine Ridge/Mt. Rowe ski area are closed. With both closed, it is mainly used for hiking and Nordic skiing. There are many views and viewpoint located near the summit.

Two-way radios have a specific range they operate within and anything outside of that will cause your radio to lose signal. A repeater will help extend your two-way radio range. Radio range can be increased through an  repeater such as the one on Mt. Rowe. Not only do radio antenna repeaters increase the range we have to communicate, but also they provide clearer voice quality for ease of communication. 

Repeater systems are located at higher elevations such as Mt. Rowe and receive and re-transmit signals using a higher power so that they reach the intended destinations. Emergency personal, police departments, commercial businesses and ambulance services all use repeaters to ensure important messages are transmitted and received. If you live in a region surrounded by high mountains or tall buildings a repeater is incredibly useful.

Repeater Offset or Shift: Repeaters are built using two different frequencies that seamlessly work together. One frequency transmits the message and the other receives it. In order to use a repeater system you will need to set up your radio so that it is set to receive the repeater’s output frequency. This frequency is how the repeater is identified (in case of the Mt Rowe repeater, 444.700 MHz). You also have to set your radio to offset during your transmission to the repeater input frequency (in this case 449.700 MHz). As a result, the radio transmits on the repeater’s input frequency and reverts to the repeater’s output frequency when your radio is receiving.

Codes: In addition, you must set up your radio with the correct private line (PL) code (a Motorola term, also called sub-audible or CTCSS– Continuous Tone Coded Squelch System) when transmitting or the repeater will not acknowledge the signal. This cuts down on interference from distant repeaters that use the same frequency and a different PL code.
