For info, I have tested the FCD running on a 20m USB cable. I believe it
might make 30m. That is the maximum you can do. This is achieved by using
active extenders. In my 20m test, I used three 5m active extenders and a 5m
passive extension.

Active extenders are nothing more than one port hubs.

I also tried running it on 10m completely passive, again no problem although
technically out of USB spec.

You know what's really interesting to me about this. With a WX type 
enclosure you could put the receiver right at the feedpoint of the antenna.

Well, maybe not, I don't know what the maximum USb cable length can be.

I'm going to look into SDR.  My Icom r-7100 has an IF out jack I could feed 
into a unit.
