Modifications for the ICOM - RogerK

cut... I'm guessing, but it could be that the rest of the diode changes are for the 10 MHz & 100 MHz digit entry (which I'd like butcould live without) or out-of-band TX, or the like.If anyone has tried only cutting D13 and resetting? Did it work? What is your serial number? Please post to the net!Mike PfluegerPacket: WD8KPZ @ W1FJITransmit range doesn't appear to be affected unfortunately. I was at least hoping for 420-450 coverage. BTW, I tried eachamateur band from 6m to 23cm. The PLL doesn't lock up at either end. Another negative is the frequency step on 220 doesn'tallow one to hit each possible repeater slot.73 de Gene WA1UXAThis modification is read 871 times.top of page19-07-1998(IC-24) IC-24AT Keyboard command summaryThis is an attempt to document all of the known key sequences for the ICO IC24AT (144/440MHz dual band hand held). Somekey sequences may be common with the IC[2,3,4]SAT, therefore a fewkey seqences fr thoseradios re also on this list. Some kesequenes requre optins (such as the PL encode/decode board).This is not designed to replace the owners manual, but to summarize the information in one place.Note: Many controls vary depending on the current mode, i.e.: Scan up/down will search frequencies when in VFO mode, andwill scan meory channels when in Memory mode.

Start with the radio OFF, then hold down the indicated keys, andcontinue to hold them while turning the power ON. Some 'modes' override others.
