So this little video came about because I sold a President Lincoln II+ to a guy on eBay and after he installed it in his van he lost the 11m band. This is because a reset had been performed on the radio meaning that although the radio was modified it had defaulted back to the Ham bands only (10m and 12m). This video shows how to restore those missing channels. I hope people find it useful. Please note, this only works when the hardware mod has been done inside the radio and that involves inserting a resistor to expand the band coverage.
If you want to see the full modification process then check out the video from Bells CB Radio in the USA here: https://www.youtube.com/watch?v=2ABvhZuIQ9E
