For those times when you and your group are far apart, the Uniden GMR5088-2CKHS boasts a 50-mile maximum range. Like all of Uniden’s two-way radios, this maximum range is tested in natural mountain to valley conditions. This maximum range is achieved with an unobstructed line of sight and ideal topographical and atmospheric conditions, so it’s likely that your maximum range will be somewhat less if you’re operating your radio in obstruction and interference-heavy locales. Additionally, 50 miles can only be achieved with the GMRS channels, while the FRS channels operate with roughly a 5-mile radius.

The Elements

Uniden understands that getting caught out by the weather is miserable at best and life-threatening at worst. Therefore, like man y of their models, the GMR5088-2CKHS two-pack doubles up as a weather alert radio, giving you access to 7 NOAA weather channels and transmits all the latest weather alerts. This lets you stay prepared, and should a warning occur in your area, you can take cover and make suitable precautions before the bad weather hits. Stay safe, and don’t let Mother Nature take you by surprise.

Sadly, we all know that luck won’t always be on our side. We’ll either be caught in heavy rain or we’ll be fording a stream, wading, or perhaps travelling over the open water, and we’ll develop a case of butter fingers, right before we hear the dreaded plop, splash. Now, with many two-way radios, that’d be the end. Not so with this rugged model. It’s waterproof to JIS level 7, so it’s submersible for up to 30 minutes, without taking damage, providing all the rubber port covers are in place. And, because nobody wants to be diving into cold water to grub around for the lost radio, these guys bob right to the surface and float, just waiting for you to easily and safely scoop them up.

Channel Options

The Uniden GRMR5088-2CKHS two-way radio double pack gives you access to 7 FRS channels that do not require any kind of license to operate. These channels do get busy in heavily trafficked areas, but they are a solid choice for shorter range transmissions of up to 5 miles. You also have access to 15 GMRS channels for longer range transmissions, but you do need the appropriate license to utilize these channels.

To cut out all the transmission that you don’t want to hear, you and your group can choose to use any of the 284 privacy codes. As long as you’re all tuned into the same channel and code, you can communicate in peace. If you’re getting a lot of interference or unwanted transmissions on your channel and privacy code, as long as you all have compatible radios, your entire group can switch to Group Mode. Once set up, one person can change channel as necessary for every member of the group from their single handset. For those times when you want to talk to just one person from your party – or even a small handful – you can activate Direct Call, choose their nickname, and call their radios directly. Their radio emits a call tone and, once they answer, you can converse privately, much like using a cell phone.


Your Uniden two-way radio two-pack comes with 6 AA NiMH batteries that can be recharged via the docking cradle and microUSB AC adapter and, depending on how you use your radio, you can get up to 10 hours of use from a single charge. For those times when you don’t have any way of charging your radios, you can insert disposable AA alkaline batteries. Keep a couple of packs with your radio so you never run out of juice unexpectedly .Just remember never to try and charge disposable batteries, as this can damage your radio.

Now, to optimize battery life, you only want to use the weather alert radio feature when necessary. Similarly, if your group is has a reasonably good signal and is within a 5-mile radius, conserve battery by sticking to FRS channels, as these 7 channels draw less effective radiating power via the antenna to communicate than GMRS channels.

Sometimes, your team is more than 5 miles away, or there’s lots of obstructions around (perhaps you’re in a forested area or you’re exploring the urban jungle), or perhaps there’s lots of atmospheric interference. In this case, you may need to give your transmission a bit of a boost, rather than just using your regular PTT. So, hit the Boost button. This temporarily draws more power, but is does help get your transmission through.


Illuminate the night when nature calls, or when you need to find your way around camp, with the built in LED flashlight. In times of emergency, you can switch it from flashlight mode to SOS mode, and it will strobe an SOS beacon.
