you need to use a type certified transmitter under part 15
Only partly true. If you choose to use a transmitter that is not type accepted the responsibility for Part 15 compliance falls on the user. So scratch built, kits and mods are OK as long as you are willing to accept responsibility for assuring your final set up meets the requirements of Part 15.
On FM it is very difficult to be compliant and regulatory scrutiny has never been tighter.
on AM the FCC appears to be getting some teeth
THe FCC always responds to complaints from licensees. If your broadcast upsets a licensed station your operation will be looked at. If you exceed feld strength or use a mis-configured set-up you will be asked to stop broadcasting and to change your set-up before you broadcast again.
If you don’t cooperate you will get an NOUO
If you still don’t cooperate you will get an NAL
So, legal broadcasting without a license is challenging and the ultimate range is severly limited – but it’s still FUN 🙂
Experimental broadcasting for a better tomorrow!
