I was pondering our archive and noticed that we’ve never given attention to some of the more interesting amateur radio hacks. I’d say that most of the amateur radios on the market are susceptible to modding. The mods generally result in a wider band of transmission or reception. I used to own an Icom 706MKII – a serious mobile rig that, after removing a diode or two, gains an extremely wide transmission band. You can find a range of mods here – most are just a quick google away. (The FCC won’t be happy if they find you using an unlicensed device, but there’s an argument for having the capability in case of emergency.)
