ICOM IC-208H DUAL BAND MOBILE
Extended RX/TX By: KD4CWB
Place the radio with the front panel toward you and bottom side / speaker side UP.
Remove the (4) screws located in each corner.
*CAREFUL! Go slow, you will need to disconnect the speaker cable while removing the cover.
Look at the lower right hand corner of the main printed circuit board.
*You should see a silver crystal with the number "D196D3C" printed on it.
*Just above the crystal, you should see an (8x8) matrix pad (see below diagram).

o o o o o o o-o <-- Remove

Note: there are ONLY (2) resistors in place. (Bottom right and the one directly above it).
*REMOVE BOTH RESISTORS [Do NOT attempt this unless you know how to use a low wattage soldering iron]
[Image: ]
*RESET THE RADIO, hold the [SET LOCK] and [S.MW-MW] buttonsdown during power-up.
DONE! New RX/TX Ranges
118.0000 - 135.9875 RX-AM only
136.0000 - 173.9875 RX & TX (15% RF power fall-off at lower freq, Full power at high freq)
230.0000 - 399.9875 RX only
400.0000 - 478.9875 RX & TX (Do NOT transmit below 410MHz on HI-PWR, VSWR fold-back)
479.0000 - 549.9875 RX only
810.0000 - 849.0000 RX only
849.0000 - 869.0000 RX only
894.0000 - 999.9875 RX only
