Can someone please explain to me how the IF is usefull ?
Does the radio become "narrow band" after the IF stages ?
What determines the radio IF bandwdith ?
Say my ICOM 706 can RX 430 - 450 MHZ, does that imply the whole 20 MHz is there centered on 10.7 MHz ?

I'm going to look into SDR. My Icom r-7100 has an IF out jack I could feed into a unit.
That was my first thought too, but R-7000 receiver's IF is at 10.7 MHz and the FCD only goes down to 64 MHz.
On the other hand, the R7000's tuning range isn't that different from the FCD, and I bet the FCD has better specs, so why bother with the receiver?
