4.0 out of 5 stars Good value, June 22, 2004

By A Customer

This review is from: Uniden GMR645-2CK 6-Mile 22-Channel GMRS/FRS Two-Way Radios (Pair) (Electronics)

These do a pretty good job for the money. I haven't tried them on water yet, but in the city, with houses, trees and other things blocking the line of sight, we get a little over a mile in range. The NOAA weather stations come in loud and clear so far. This will be a great feature when we're out hiking. They're also pretty compact and light. When you consider the fact that these come with NiMH rechargeable packs (or you can use 4 AAA's per radio) and the recharger base, you get quite a bit for your dollar. On the other hand, it looks like the Uniden GMR855 might give you a little bit better range (without the NOAA weather feature) for about the same price, but if you can get these on sale or with a rebate, it's hard to lose.

We use these for car caravanning, walks, communicating around the house and yard, hiking and camping. They have performed well for us.

Nice features:
- come with chargers & 2 batteries (NiMH) - real nice.
- NOAA weather channels
- they are durable & they hold a charge for a couple of days under normal use
- they are small, but not too small
- the key layout is easy to use and hard to hit by accident (volume up/down doesn't get bumped to zero by accident!).
- the radios can be on and used when charging
- they are fun to have and easy to use
- price is right
Not so nice:
- the chargers aren't interchangeable with the 10 mile Uniden radios (model number GMR1038-2)
- take 16hrs to fully charge
- menus aren't intuitive. Keep the manual handy! (For most uses you don't have to use the menus)
- line of sight. If a straight line to your target is obstructed, you probably can't talk to them (that is the type of radios these are - not an issue specific to this model)

Range - line of sight radios are fickle. I have only used these on the low power FRS channels (8-14 are low power channels and don't require an FCC license to use). I have had intelligible conversations at 4.3 miles (as a crow flies) on low power. And I have lost radio contact at 1/4 mile on other occasions.

Fine radios at a fine price.

I purchased these radios (under $40 for the pair) for use in my pool service business. They are great on residential job sites and working in building complexes; however, any use beyond that and the range is too poor. I tried using them between two job sites several blocks away (about 1/4 mile) and they were useless. I had hoped to use the radios for hunting/hiking/etc. but I don't think the range is adequate. Still, you can't beat the value for short range applications. For more demanding applications, I would research using a more powerful commercially available radio system.
