Matt, The KX3 will have about 30 dB better dynamic range than the IC-7000, even without the roofing filter.
I'm not knocking the 7000 -- it's a versatile little rig. It's just a question of how much RX performance you want. Of course the KX3's ergonomics are completely different, too. 73, Wayne N6KR On Dec 29, 2011, at 5:43 PM, Matt Maguire wrote: > Hi Johnny, > > I thought about an FT817, but my reasoning was similar to the points > you listed.
