Yes, if distributed that way. No, if modified by the end user. I don't remember the CFR off hand, but the FCC explicitly allows anyone to use small numbers of uncertified devices. It would still be a violation if those devices don't otherwise follow regulations, but using modified hardware or software isn't itself prohibited.

15.23, but it applies specifically to "home-built devices", so I'm not sure if modification of a commercially available device would be within scope. Devices constructed from a kit are specifically excluded. https://www.ecfr.gov/current/title-47/section-15.23 https://www.ecfr.gov/current/title-47/section-15.23

  They excluded kits, because there was a thriving market for pirate radio station transmitters sold as kits.

  Are home-built devices allowed to be made using things like pre-manufactured valves and transistors? What about integrated circuits? Where's the line drawn? Am I allowed to order some parts from Digikey and assemble them into a widget, or must I start closer to the beginning by mining my own ores?

    If you can't make your own protons store bought is okay.

This could change depending on the fallout from the current drone saga, no pun intended. Or other upcoming events. Even if it's not FCC regulations, but some other agencies, there may be some close re-examination of what's allowed due to safety. I'm guessing certain manufacturers are going to be impacted more than others. I'm sorry for the uncertainty in boardrooms and garages across the world. I diversified my embedded sources but damn it's annoying. But I suppose that's the machine. I just picked up an ESP32-C6 for some mostly legal Bluetooth and maybe Zigbee experiments. I don't plan on hacking to this level, the Rust ecosystem is welcoming enough to make just building fun so far. On a side note, I stepped in shit today. I know I have five q-tips in storage somewhere. And a few more in the closet. Sorry for the weird tangent.

  Chevron being tossed also makes this all immensely more complicated

    I'm sorry, yeah. It's more than boardrooms and garages. I'm sorry to all. Financial independence is just... it's nice having on top of other security and basic life guarantees. Enjoy it while it is there.

The power and directionality rules for ISM bands are good guidelines for not interfering with other's use of the band. If you have another story that makes interference unlikely, it probably also makes it unlikely to get caught. Plenty of items for sale on Amazon don't have any silkscreen on chips or boards, much less an FCC id. If they can get away with it...
