433MHz is a freeband (ISM). Still, you are supposed to be clean.
433 is NOT an ISM band in the US (or in region 2, for that matter), but
it is in Region 1 (EU), so there's lots of parts available.
It is also not an Part 15 band (distinguish from Part 18 ISM)...
27 MHz, 49 MHz, 900 MHz, 2.45 GHz, those are ISM and Part 15 bands...

A badly tuned/designed super-regenerative receiver can put out a lot of
garbage. For commercial products, the receiver needs FCC approval to
ensure this doesn't happen.
