Are any manufacturers making new FRS radios with all of the authorized 22 channels and new power levels? I haven't seen any advertisements for such.

Copy that. I'm a ham but I have frequent road trips with people that aren't. I just looking for some decent hand held units that I can just pass out. I'm guessing the Motorola or Uniden models would be okay. Just asking because its been so long since I've looked at these.

The Motorola Talkabouts have been my favorites for FRS.
Nope. At least the supposedly 2 W model that Home Depot carries is made by Altis Technology in China and according to the FCC grant it puts out 871 mW high power and 251 mW low power.Looks like Dewalt is making FRS two watters.
I do this too but don't use FRS at all. I use Motorola DLR and DTR sereis 900MHz FHSS digital on-site business radios instead of FRS.
I never knew this unlicensed service existed and using spread spectrum is a nice bonus as far as security. I see pricing is anywhere between $200+ to $300+ depending how many channels you want which could be worth it if you use them often.
With 1 watt at 900 Mhz and spread spectrum, what kind of distance can you expect in a city, say one person in a house and one walking around the neighborhood where you would have other house between the two users? What kind of distance would you expect outdoors with clear line of sight between two units?
I've tested the DTR700s in a number of different situations and was quite impressed. With a clear line of sight in a rural area (for instance, ridge to valley), I've gotten a clear signal at over 5 miles distance, and that's nothing compared to what others have reported. In a hilly urban setting (San Francisco) where line of sight is obstructed by dense houses, I reliably see a bit over one mile range from inside the house to the street. If you have some elevation it's even more. Driving around Los Angeles with one unit sitting inside a motel room at about 100 ft higher than average terrain and the other in a moving car, I got signal within a 2-mile radius. I echo n1das in recommending these radios for use in residential neighborhoods. Where they fail is seeing around hills and into canyons, unless by some chance you get a solid reflection and the radios can handshake. I took one into the northern California woods and tried to talk into a river valley, and the signal wouldn't pass through the rise in the landscape. Otherwise these are great radios.

Well I can answer that one.I have pushed these things to the absolute limits. In the desert where I live, I have gone out over 25 miles with a pair of DTR650s. I actually ran out of road before I ran out of range. Of course there were a few dead spots here and there, but for the most part, had full coverage. Radio #1 was up on my balcony about 10' high, and the other was in a car. There were times I had to get out of the vehicle, of course.
Have had the full cruise ship coverage that N1DAS speaks of, as well as amazing coverage once at the DFW airport when I was passing through and cell phones went down. If you know that airport, you know the terminals are huge. Not only had coverage through an entire terminal, but also from one terminal to another. I was blown away.
The DTR series has existed since about 2006, 1 year before the first iPhone came out. Available DTR models were DTR410, DTR550, and DTR650......
Okay for the Motorola DTR and DRL 900 MHz radios, how crowded are the channels? You can get them with 2 channels, 6 channels or 20 channels. Can you listen to someone else on the same channel or are there different spread spectrum codes you have to set for two radios to talk to each other?
Is it possible to listen to the default configured radios on a scanner? My searches aren't finding anything.I am finding people tend to use them right out of the box at the factory default settings like FRS bubble packs. I have monitored activity on the default public talkgroups ("channels") from time to time in my travels. The local Costco Wholesale near me uses DLR radios at the factory defaults and I hear them when in range. I have a set of customized channels in my radios in addition to the default channels so I can monitor the defaults and also have my secure channels.
When I was last down in FL on vacation, I had several GMRS radios with me and also brought along several DTRs. My wife and I and a friend used the DTRs exclusively for our local simplex chatter because they worked so well. We didn't bother with GMRS at all.
