I purchased a DJ-500 Alinco handheld and am having trouble getting it to recieve any frequency in the 70cm band. I am able to program repeaters and simples frequencies in the 2 meter band but when I type any number after 44 it kicks me back to the main menu. I am able to code in the alpha numeric names for channels but then I am unable to save them. I could really use some help if anyone is able. thank you.
