I've got a few 220 MHz radios. I agree, there is VERY little use, but a few years ago I was scanning on my IC-38A (R.I.P.) and got into a repeater in Columbus OH from Versailles KY! When 2M is open, it's even more fun to DX on 220 MHz. Propagation on 220 is kind of like a mix of 2M and 70CM, and when it's open, it's really fun to geek out with the other 220 fans!
