27 MHz CB

When CB was first legal in the UK, it was very busy. I seem to recall monitoring, but don't think I ever transmitted on CB. 

I still have pair of 1 channel CB handhelds that I used once many years later. These were going to be converted to 10m FM on 29.6 MHz, but never were.  A range of 1 km back-to-back was achieved that surprised me. 

These days I think it is much quieter with advent of the internet and 446 licence free. In the last century we also had a 934 MHz CB band in the UK! 

These days there are far fewer users as these alternatives exist for chatting, leaving the CB frequencies for farmers and any enthusiasts left.

CB gear is low cost as there is lots around ....and probably not selling!
