15-22 are GMRS simplex which can be used with a mobile GMRS Radio up to 50 watts with the appropriate license. Rather than offering illegal advice with outdated information you could have advised the OP look into a GMRS license. It's $35, good for ten years and the only test is navigating the FCC website.
The OP was a looking for a way to communicate with his friend in the event of a medical emergency, in case cellphones were not an option. He has health issues, is not working, and was already in possession of two Baofeng radios. I did not want to send him on a shopping spree for new radios or advise him to get a GMRS license, which would also require his friend to obtain one as well.
FRS seemed like a better fit for his puposes, provided his friend was nearby. The OP never shared how far away his friend lives.
I have already conceded the point that it was poor advice, and advised him in a subsequent post to purchase a pair of FRS bubblepack radios.
Yes, they are GMRS (50W) and FRS (2W) simplex. From the RR Wiki, 15-22 are also repeater outputs, as previously stated.

- (1) Shared FRS and GMRS simplex.
- (2) GMRS repeater output.
- (3) GMRS repeater input only.
- (4) Color frequencies on some business radios, 462.575-White, 462.625-Black, 462.675-Orange
There has even been some chatter that the FCC is ok with part 90 radios being used for GMRS as long as the user is licensed and using the radio within the confines of the legal limits although I have not found any official statement to that effect.
Yes, this has been discussed before in a number of threads in the GMRS forum. I have also not seen any official statements cited in these threads or anywhere on the FCC's website. Definitely a source of some uncertainty, which hopefully the FCC will clarify.
OK!? Whatever.I'm sorry you're so offended by my dislike that you had to stalk my posts and dislike my clearly accurate information from 7 months ago... It did give me a bit of a laugh though so I do appreciate that!
