Procedure:
1. Detach the front panel from the main chassis.
2. Remove the bottom cover of the transceiver by removing the 4 screws on
the bottom of the cover and loosening the 4 screws on the side of the
unit.
3. Orient the radio so the bottom is up and the front panel area is near
your chest. Near the front panel area you will find a large board, this
is the control unit.
4. Remove the chip resistors "Y" noted in the diagram below, and reinstall
them in position "Z" as shown.
5. Reinstall the bottom cover of the transceiver and reattach the front
panel.
6. Reset the microprocessor. Press and hold the MR key while the power is
switched on. Then release the MR key. This will erase all operator
programmed data.
7. The frequency range after modification will be:
28 Mhz Band: RX: 18.0 thru 54.0 Mhz
TX: 26.0 thru 45.0 Mhz
50 Mhz Band: RX: 40.0 thru 90.0 Mhz
TX: 46.0 thru 76.0 Mhz
144 Mhz Band: TX: 136.0 thru 174.0 Mhz
220 Mhz Band: RX: 215.0 thru 260.0 Mhz
TX: 215.0 thru 235.0 Mhz
440 Mhz Band: TX: 410.0 thru 470.0 Mhz
1.2 Ghz Band RX/TX: 1100.0 thru 1400.0 Mhz
Please note that these are theoretical ranges only. Not
all radios will be capable of tuning the entire range.
