Ich habe folgende Anleitung im Netz gefunden:
Hat das schon mal jemand gemacht. Ich würde es gerne ausprobieren, möchte aber nix kaputt machen.The mod is easy. This will give you 137-174mhz and 410-470mhz Tx/Rx.
1. Disconnect power and antenna (like, you would'nt of done it already.)
2. Open up the case by removing the screws and gently removing the cover and unpluging the speaker.
3. Locate and CUT the GREEN WIRE on the CONTROL BOARD ( the vertical board behind the control panel.
4. Reassemble the radio.
5. RESET THE MICROPROCESSOR (so much for the memory!)
(press and hold [D/M] & [REV] & [ENT] & turn the power on)
(turn off the radio).
(press and hold [SCAN] & [HOME] & turn on the radio - extended RX mod).
