Help Please, I am in Stoke on Trent on the Fenton repeater but have trouble receiving various channels. The box in auto scan assigns frequencies which are not the best available to me at the moment channel 5 is on 68 but better signals are in the 20's and 30's. If I do a manual scan from the set up/help/red button page I can find better frequencies .How, if possible do I store the new frequency as the box when I exit and then go back in reverts back to the old setting.In auto scan I get 12 frequencies and 105 programmes.
