Uniden GMR1635-2

Use the radios when camping, hiking, hunting, or even for keeping in contact with another person in town.

Great for Hiking, Hunting, and Plenty More

Call Tone and Roger Beep

A call tone and roger beep helps you know when transmissions to and from someone are beginning or ending. The GMR1635-2 features both, and you can turn the roger beep off if you’d prefer.

Easily Reduce Interference

The GMR1635-2 is equipped with an automatic squelch system, which shuts off weak transmissions and unwanted noise caused by terrain conditions or reaching your your range limit.

AAA Battery Power With Automatic Power Save

GMR1635-2 radios are powered by three AAA batteries, and features a unique circuit designed to dramatically extend battery life. If there are neither transmissions nor incoming calls for 2 seconds, the radio switches to Power Save mode. The radio is still able to receive transmissions in this mode.

In addition, the radio features a battery strength meter, to show you when it’s time to charge.

Wide 16-Mile Range

Use the radios when camping, hiking, hunting, or even for keeping in contact with another person in town. The GMR1635-2 radios offer plenty of options with a range of up to 16 miles. (As with all GMRS radios, you’ll get more range in open terrain than in areas with many high buildings.)

Finding Channels

The GMR1635-2 radio boasts a channel scan feature that lets you easily scan all 22 channels (15 GMRS, 7 FRS). When an active channel is detected, the unit pauses on that channel until the channel is clear. After a two-second delay, the radio will continute scanning. Pressing the PTT (aka Push to Transmit) button while the scan is paused on a channel will allow you to transmit on that channel.

Note: License Required

Note that the GMR1635-2 radios operate on the General Mobile Radio Service (GMRS) frequencies, which require a Federal Communications Commission License to operate. For licensing information and application forms call (800) 418-3676 or (888) 225- 5322. No license is required for operating FRS channels 8-14 or any channel in Canada.

    DO NOT BUY RECHARGEABLE VERSION DO NOT BUY THE RECHARGEABLE ONES!!Instead of regular triple A batteries, they send you triple A rechargeable batteries inside, AND THEY ARE THE WORST rechargeable batteries ever.We weren’t sure what the problem was when one kept losing the charge. We thought it was busted. But then the other started to die really quickly. We are talking about only a few minutes of use maybe twice a day.So you’re paying more money for nothing really, because the battery life of the…

    1635-2 Review: Kid LOVES The kid loves these…. I bought these to replace some cheap ones my 7-year old had that were practically worthless.The important stuff:1. NO Way does this get the 16 miles it claims. OK, we haven’t taken it out to stand on a hill without any buildings, so maybe that’s the problem. We do, however, get about 1.5-2 miles in suburbia around houses, trees, etc. We tested it in a car moving away from the house a couple of times. – so that’s good enough for us. We also found it reached a…
