Model: ICOM / IC-2SAT Bulletin: B4010 Subject: Software modification from keypad IF you own the IC2SAT, newer version, here are the REAL button mods for extended listening and 6 digit entry. With the radio OFF. Press these keys and hold them while the LCD display shows all. Let them loose when a normal looking frequency shows. Press # - B - L(ight) buttons and turn on the little bugger. This gives extended listening. Now turn the HT OFF again and press 3 -L(ight) buttons while turning the rig on again. This will enable your entering ALL six digits not just 4. Makes it easy to enter 174999 not turning that knob all day. Pat Wilson KC4TTM
