This site is dedicated to everyone world wide that has ever used 27 Mhz or the ELEVEN Metre Band! 
Also known as 27 Mhz Citizens Band CB radio & FREEBAND  which could be anywhere from 26.500 to 27.995 just below the Ham 10m Band.

We do not condone this, just see it as a fact of DX. Use of many of these frequencies is not legal in most countries if outside the regulation CB allocation.


Read our OPEN FORUMS on FreeBand DX.
Best way to keep open is to set the chat page as a desktop item so it is
always open in the background.
