This is a software mod to open up the receiver for the IC-2GXAT.
(YOU DO NOT NEED TO EVEN TAKE THE RADIO APART!)
- Turn off the radio.
- Press and hold the, F KEY, Scan and Dup keys.
- While holding all 3 keys turn on the radio, continue to hold the keys for about 3 seconds WAITING until the display returns to normal before releasing the keys.
I did this to my HT and it receives from 50Mhz – 204Mhz.
