The RRTG petition linked in Carmine5’s post makes the surprising statement that, up to 1968, unlicensed AM operation was legal for everyone at power levels up to 100 watts. I thought that the rules in 1968 were nearly the same as given in Section 15.219 today.
Where did RRTG’s assertion come from? If it turns out that RRTG’s statement is not true, it would hurt the chances of the petition ever being considered by the FCC.
