It's not specifically not allowing these devices, it's broadcasting on a restricted frequency without the proper license. The FCC regulates who can broadcast on which frequencies. Getting a ham license can open it up a bit, but there are still regulations to follow.

I wish they would open up 214-400 THz range. Then instead of charging everyone $99/month for poor cell phone service, we can charge $99/month just for living.

    I think parent might have meant the Black-body radiation of a human [1], but was off by an order of magnitude... should be 14 um to 7.5 um wavelength = 21.4 THz to 40.0 THz.

He is not offering the product for sale. It is experimental and therefore allowed.

  Actually no. Any experimental device must be covered by the appropriate experimental class license. Think about it. Any dumb CBer could claim that his homebrew Linear is "Experimental".

    That's different. CBers are broadcasting. FCC gives you exemption for up to five units [1]. You are also exempted during development; how else could you even build the thing. FCC of course reserves the right to come in and tell you that your device is messing up the neighborhood and to cut it out. [2][3] Your device can't be used explicitly for the purpose of broadcast or jamming. The experimental license is for those who actually want to broadcast/communicate on those restricted frequencies.

      CB'ers are not "Broadcasting". Broadcasting has a specific meaning and it is not permitted under a CB license. And yes, you are exempted for ownership while under development, but your organisation needs a written license or permit, plus you cannot transmit outside a screened room. The Experimental License is for those who wish to Transmit outside a screened room. Note that the O.P. is in Finland, not USA and the licensing details vary with each country.

        Thanks for that. You are right. Broadcasting was the wrong word. Given your extensive experience, then perhaps you can help clarify something for me: How do you reconcile the experimental license requirement with the FCC part 15 exemption I linked to? For reference, my background is hardware development and I have done a fair bit of RF but they've all been in ISM band and we never had to get FCC approval until we intended to make/market the product and don't know of anyone who has ever obtained an experimental license, or a license of any kind. Was this because of the ISM band or are people technically doing it wrong, but getting away with it because the device isn't radiating so high that it actually interferes with a neighbour and leading to an FCC complaint?
