  1. Hello,
    I have HBR4F but the VFO setting at Caliberation is off. Radio doesn’t tune any station any more. Please help me how to correctly re-set so it functions properly.
    Thank you,
    Khan

    • Hello,
      In every unit we put sticker with tunning/setting value, as long as no modification you can set the value back. You can go to the hambuilder.com web site to get the user manual of your unit.
      Regards
