    I doubt if you'll get thrown into Leavenworth, but there are restrictions on use of FRS for data:

    The most onerous restriction seems to be that the data transmission can't exceed one second, and there can't be more than one in a thirty-second period.

    If it's in your basement and not radiating outside your own property, it's probably not a serious violation. But it's probably not a good idea to use it for actual communications purposes, unless you follow the rules, which limit the utility quite a bit.

    You could probably accomplish the same thing with a Part 15 baby monitor, and not have to worry about breaking the rules.

    thanks for the info I couldn't find that. yea Im not planning on blasting people the baby monitor is a fun idea, I just have FRS radios at my disposal

    but I will update my blog post with your information thanks!

    im just wanting to learn how to use and recognize poor digital signals properly so some day when I can move to a good antenna location I can listen to something other then CW

    If you're in the Denver field office's territory I wouldn't do it. They have a mean lady there that busted somebody for having a part 15 device that was less than 1dB over the limit. Fined him $10,000 for that. She's really making friends and influencing people!

    Do you have a link for that?

    Your getting the straight scoop on digital transmissions not being legal on FRS is correct. I think that the 1 second transmission was something added to the rules to make GPS location systems work.

    If I'm not mistaken, digital is permitted on MURS. I know you have FRS radios, but for anyyone with legal MURS radios, perhaps this is useful info.
