[TenTec] How to Choose an SDR RX for the Pan-Adapter?

[Spencer]

I have a Dell dual core laptop that works with a nooelec dongle. I 
believe its asking a lot of a PC to do
what I want. The delay through the computer  is a major issue. The 
filtering needs to be in the SDR.  I have connected my dongle to the 1st 
IF of 2 radios. What the SDR does is amazing.
   Im not touching my OMNI VII just yet.
