Tools required:
l #0 Philips head screwdriver
l 10 - 15 watt pencil tip soldering iron
l Magnifying glass
l Tweezers
Remove the TOP cover by removing three Philips head screws on the top and one on each side. Move the speaker bracket out of the way. Locate D-59, this is a three terminal SMD diode in an SOT package, about 1 x 3 mm (with the radio front panel oriented towards you, D-59 is located in a row of SMD diodes just to the right of the ribbon cable header above the 9 MHz SSB filter FL-30. There are pads for 5 diodes with only three installed. D-59 is the second from the left).
Using tweezers and a low-wattage soldering iron (and magnifying glass, if necessary) remove D-59 by applying some heat to the single leg side of the device while lifting gently, then apply heat to the other two legs and removing the device. Be careful not to apply too much heat, not to rip or burn any traces or not to leave excess solder on the PCB. Replace the speaker bracket and top cover.
Apply power and reset the microprocessor.
TX = 1600 kHz - 54.00 MHz and 118.000 - 174.000 MHz
