Subject: Mods for the Ranger RCI-2970 10 meter radio. Frequency Coverage Modification: 1. Remove the top cover to get to the PC board with the jumper pins. They will be on a PC board immediately behind the front panel. 2. Locate the jumper pins, they are on the left side if you are looking at the front of the radio. There are an upper and a lower set of two pins. There will be a jumper on the lower set of pins (factory setting). 3. Move the jumper from the lower set of pins to the upper set of pins to expand coverage to 26 MHz - 30 MHz. The radio will read out in both MHz and CB channels. A couple of the function keys will act slightly different than described in the manual. You'll figure it out. 4. If you remove the jumper entirely, frequency coverage changes to 27.965 MHz - 27.405 MHz with CB channel and MHz readout. Some of the function keys will act different than described in the manual. You'll figure it out. 5. To return the radio to factory settings, move the jumper from the upper set of pins to the lower set of pins. Anonymous
