FRS & GMRS Radio Guide
Q: Is it going to work outside US??
A: If you talk while riding a kangaroo the voice quality is bouncy
Q: 2 pairs working simultaneously
A: Yes if on same channel.
Q: Will these work in houses 8 miles apart?
A: Not very good
A: I purchased mine in April 2017 and it came with belt clips and a charger. Hope this helps.
A: Unless your home is 16 miles across, these should work fine. One pair is two items. So, unless there are more than two of you using them, one pair should be enough. It goes without saying that you need to buy enough radios for everyone with whom you wish to communicate. These are rechargeable by the same cable that charges a standard cell phone IF YOU USE THE BATTERIES THAT COME WITH THEM. However, they come with Nickel Metal Hydride batteries which, while better than the older technology Nickel Cadmium, are still a lower capacity than alkaline and Lithium based alkaline batteries (which are not rechargeable). The radios will run longer on alkaline batteries but then will not be rechargeable. They will interfere only with other radios on the same channel or, if they're close enough, possibly on a nearby channel, but that's why they have some 22 channels. Keep in mind though that the GMRS channels require a license (not that anybody seems to care) while the FRS channels do not. In all cases, the lowest power setting that can be used adequately should be used to limit interference to other radios, if these even have a power setting.
A: I'm sure your venue has come and gone in the four months since you asked your question but these radios are advertised as having a 16 mile range. As long as your venue is smaller than that, I would hazard a guess as to suggest they will work. For what it's worth, FM radios like these are known as "line of sight", meaning their range is limited to the distance you can see to the horizon since unlike lower frequency signals they don't propagate over the horizon without special high end equipment. Unless you're standing on a hill, building, or such, that distance is generally about twelve miles, not sixteen. Even at that, twelve miles is ten to a hundred times more than most people buying these will need
Q: How many batteries does each radio need?
A: 3 for each radio
A: The charging icon will continue to show you will need to time the charge. 8 hours
