I am guessing this is going to be a multi-op station? Otherwise, why need
four separate IF rigs?
I've been using one IF radio in my QRP portable operations for years.
I've been using an HTX-100 modified to bypass/remove the final amp as a 28
MHz IF for 50, 144, 222 and 432 MHz. I built a switching box to switch
transverters (and bands). I like the HTX-100 because it's small and
lightweight, you can get it cheaply now, I find I don't need the bells
and whistles, it works fine on SSB and CW, and it draws little power so
it doesn't run down the batteries. I load the memories with frequencies
I'm likely to be using for the different bands before the contest so I can
quickly switch bands.
One caveat about the HTX-100, though, is that it has become a favorite
radio of freebanders. If you eye one on eBay, try to find out if the
seller is a licensed ham and whether he modified it. If he's a freebander
he's probably hacked it up somewhat inside or detuned all the internal
Otherwise, you could go FT-817's if you want something small, or for just
about the ultimate performance in my opinion but a much larger rig, you
could go with TS-850's. These make outstanding IF radios.
I hope this helps.
