IC04AT.5 The ICOM thumbwheel VHF handheld IC-2AT, can also be modified for 150 MHz transceive, but once you make the mod, you lose all of your 2-meter frequencies. You would be better to simply go out and buy a type-accepted VHF transceiver as opposed to ruining your present 2-meter ICOM IC-2AT! The older high frequency radios with VFO tuning (as opposed to PLL tuning) do not easily allow any type of modification for expanded transmit or receive coverage. It would require so much modification that you would be ill-advised to try and step up any Yaesu FT 101 series, 980, Kenwood 120, Kenwood 520, 820 or any of the older ICOMs. For the old ICOM 720, the transmitter is unlocked by snipping the blue wire that's at the very end of the top hatch cover to the left middle side of the transceiver. Again, using your ham radio outside of normal ham radio band limits is illegal except in an emergency or where specifically authorized. Keep this in mind before opening up your set and attempting any modification. This article is presented purely for the safety sake of mariners, aviators, and backpackers who lay their lives on that one piece of radio equipment that will come to the rescue when an emergency should arise.
