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.

wrong.All that happened is that they gave model planes 35Mhz, and
legalised CBs They still interfered with still legal 27Mhz kit

No. Only imported and Illegal, AM CB radios (26.965 27.405 MHz)
buggered up 27 MHz RC (26.995 27.255 MHz).

In 1981 licenced UK legal FM CB radio appeared (27.60125 27.99125
MHz), these legal sets did not bugger up the 27 MHz RC frequencies.

However since 2006 the CEPT/EU frequencies can be used in the UK,
with type approved kit. The CEPT/EU frequencies are the same as the,
illegal until 2006, AM ones.
