He could go with a 10.7 MHz fixed IF Softrock for about $30 (with the special crystal) instead of $175 for the FCD and maybe have a chance at getting one sooner than later if he really wanted to use it with the ICOM.

A soundcard is needed for a softrock, but I have used a $50 USB one in the past from China no problem if he can't use the built in one (like on a laptop).

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?
