Ok, so I finally upgraded my mobile vhf to a D710. Now a friend from another website and I are assessing what to get for HF. Both of us are licensed generals, with no hf experience. He has a house, I have an apartment. We've brought up the icom 718 and 7200, the yaseu 450(all flavors), 857 and 897, and kenwood 480(both flavors), and I threw in the alinco sr8. We have no 10m repeaters along this side of Colorado, but there are some 6m repeaters. Obviously the 7200 and 450 will not require filters, but the rest use mechanical filters at varying expense. How much of a need is there for the narrower filters for ssb work? I think both of us want radios that could be made portable, possibly mobile. Looking for anyone with experience with these rigs, their input, likes and dislikes. I've also thought about the older yaesu rigs, 757, 890, and 900.
