I was very fond of my Heil HM-10 when I ran Yaesu but, no matter what Bob might say, dynamics are not good partners with ICOM radios - even the new models. The ICOM stock mic for the 7300 is hard to fault - at least in audio terms. Personally, I like a desk mic, so I forked out the preposterously high price for an ICOM SM-50 and I'm extremely pleased with it - apart from the price!
