The Uniden® GMR2838-2CK 2-way radio is a lightweight, palm-sized device that’s equipped with many valuable features. Use it at sporting events, to stay in contact with family and friends, for hiking or skiing, in the great outdoors, or during a neighborhood watch for vital communication. This set includes 2 radios, a charging cradle, and NiMH batteries.
This pair of two-way radios is perfect for hunters, hikers, or any other outdoors type, offering a range of up to 28 miles, 22 GMRS/FRS channels with 121 privacy codes, a wealth of user-friendly features, and J1S4 waterproofing for use in rain and damp environments.

The GMR2838 boasts 22 channels, including 7 FRS and 15 GMRS channels, along with 121 privacy codes to help reduce interference from other users. A channel scan feature lets you easily scan all 22 channels for activity, pausing on each active channel for two seconds. You can also monitor a single channel for any signals.
These radios will give you a range of up to 28 miles, opening up your options considerably (as with any two-way radio, the less obstructions the more range you’ll achieve).
The GMR2838 boasts a weatherproof shell that meets rigid J1S4 compliant standards, which makes them perfect for rainy weather and damp environments.



These radios are powered by included NiMH battery packs. The included charging kit keeps your radio ready for action, and a battery strength meter lets you know when it’s time to charge them back up. Add Uniden’s DC-1002 adapter for easy charging in your vehicle.
The GMR2838 is an intuitive, easy-to-use radio, with features to keep things seamless. A backlit LCD display makes it easy to read, day or night. A keypad lock feature locks in key functions so they aren’t accidentally changed. A headset jack allows you to listen to radio chatter from your VOX or PTT-type headset (not included) when you’re trying not to scare away your prized prey, and the included belt clips keep your radios right at your side, for hands-free operation.
For transmitting/receiving, you can choose between five call tones to sound when calling each other, and the roger beep feature lets others know when you finish speaking.
Note that the GMR2838-2CK 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.
To promote a cleaner environment, this product was manufactured in accordance with the RoHS standard, which limits the use of substances such as lead, mercury and cadmium. The minimized packaging is also 100 percent recyclable, and printed with non-toxic inks.

This compact, well built, rugged handheld Marine radio is rated JIS8/IPX8 submersible and is packed with outstanding features. Included accessories are a rapid clip-on DC charger, and Lithium-Ion rechargeable battery.


The MHS75 covers all USA, International, and Canadian marine channels, keeping you up-to-date with all the latest marine activity.
This radio comes preprogrammed with NOAA weather channels. The Emergency/Weather Alert allows it to function as a severe weather warning radio and will also alert you to any local or national emergencies. If the NOAA issues warning while this feature is turned On, the radio sounds an alert tone. You will then hear the emergency/weather broadcast.
Triple Watch mode monitors channels 16 and 9 for a signal while you listen to the currently selected channel. The marine radio checks channel 16 and 9 for activity every 2 seconds.
These different watch modes let you monitor up to two Coast Guard Distress/Hailing channels and one weather channel along with one regular marine channel.
Automatically scan your programmed channels with Memory Channel Scan. Scanning starts from the lowest to highest channel and stops when it finds an active channel. It remains on that channel until the transmission ends, then resumes scanning after a two-second delay period.
The MHS75 ships with a rapid clip-on DC charger. Charge in any standard 12 volt DC “cigarette lighter” style outlet.
Uniden MHS75 VHF Hand Held Radio won’t give up no matter how wet it gets. Whitecap splash, gusty spray, tidal wave, whatever, this radio can take it. The Uniden MHS75 2-way Marine Radio is built rugged to take the rigors of being out on the water, day in and day out with a full JIS8 waterproof rating. It also features a floating design, and is submersible for up to 30 minutes at five feet.

Select between 1, 2.5, and 5 Watts for short- and long-range communication–this is also a convenient way to save a little battery life. In most situations, the 1 Watt transmission power is all you need. If you find yourself far away from other stations and have trouble getting a response, you may need to boost the transmission power from 1 Watt to 2.5 Watts or 5 Watts
The MHS75’s large, easy-to-read backlit LCD display and backlit keypad make it easy to use, day or night.
The MHS75 is backed by a three-year warranty.

Education

That enables a quick response to any situation, often preventing small problems from escalating into bigger ones.
Manufacturing
Success in industry depends on two things: efficiency and responsiveness. Clear communication, often in noisy environments, is essential to avoid downtime–and to enable the fastest response to production problems or injuries. The RDX Series delivers. Its rugged construction stands up to industrial environments, and its long battery life meets the demands of overtime and multi-shift operations.

Excellent service and customer satisfaction are the keys to loyalty and repeat business.

That means a more productive staff and fast response to guest needs, special events, spills and emergencies.

With clear, constant communication ensured, customer satisfaction can be taken to the next level.
Property Management
With RDX Series radios, building managers, maintenance technicians, groundskeepers and security personnel can respond fast to tenant needs or emergencies, minimizing costs and enhancing tenant satisfaction.

To keep any construction project on track, you need timely coordination from management to foremen, subcontractors, and individual tradespeople. RDX Series radios make it easy, helping keep projects on schedule, avoid errors, meet deadlines and keep costs on budget.
Rugged and reliable, the RDX Series radios undergo rigorous testing in the design process using U.S. Military 810 C, D, E and F Standards–so you can rest assured they hold up under demanding conditions. These tests are designed to simulate the very harshest environments, including:
IP54/55 Standard
In addition, the RDX Series radios are tested to IP54/55 standards, highly demanding tests for water and dust resistance. The IP54/55 tests include subjecting the radio to a high-speed, high-volume shower from all directions for three minutes. In this test, the radio must endure conditions so harsh that a human being could not survive them.
With their Military and IP ratings, the RDX Series radios have proven they’re rugged enough to handle the harsh conditions they’ll be exposed to in daily use by your customers–and provide the maximum uptime that helps drive productivity while providing exceptional value.
