Performing this modification will void any warranties.
All standard disclaimers apply. This mod is for the
- Place the radio face down on a soft towel. This avoids scratching the display and gives you a place to put the seven tiny screws to be removed.
- Remove the batteries. You will lose all of the memory contents.
- Remove the three screws on the upper rear cover, and the four screws inside the battery compartment. The rear cover can be lifted and removed easily, as there are no wires to be concerned about. The antenna connection is made by means of a gold-plated spring contact.
- Look for a small (about 1 mm) green surface mount resistor (actually a 0 ohm jumper), located on the far left side of the exposed circuit board, located to the "northwest" of the speaker. There is a marking in white letters, OP/CL, this resistor is located near by.
It is the only green component visible on the board. (This radio does not have the traditional Alinco red and blue wires which have become so familiar...)
- Carefully remove this resistor, using a small tip soldering iron, tweezers and a steady hand. The thin board can be easily damaged by a high wattage soldering iron.
- Re-assemble the radio, being careful that the thin rubber gasket is seated around the inside edge of the rear cover. Replace the batteries, press and hold the "F" button on the left side of the radio, and turn it on. The display should show all segments and markings. Release the "F" button and the radio will now be capable of operating from approximately 136.000 MHz to above 173.995 MHz, depending on the VCO's tuning. The display will blink if the VCO is taken out of its range. Re-tweeking of the VCO is not recommended.
THE NOT-SO-FINE PRINT:
- Although reception on the expanded frequencies is legal, transmission is not. This unit is not FCC type-accepted for anything but ham band (144 - 147.995 MHz) operation.
