Hi Mike,

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.

73, Zack W9SZ
