You mean like CB radio that trashed the 27MHz radio control models did?

From the mid 70's Illegal AM CB radio's mostly "imported" from the US
did. The legal UK FM CB radios introduced in 1981 didn't.
Powerline is legal.

There are comparatively few radio hams remaining on the HF bands
discussing which triode they are using to transmit and what current.

A lot of the intersting stuff seems have disappeared from HF, not
many RTTY news feeds left. WeFAX is still about and the observation
reports.
