1) If you want to work at VHF (100Mhz) and above you probably have to down convert first and then use a "soft IF" 2) The low cost of the simpler hardware is a big attraction. Thats the idea of software defined radio. Make the software work and keep the hardware simple. Of course if you want to sample at RF then "simple" does not equal "cheap"..

I think this subject is the most interesting but I have a few questions if anyone is in the mood to help. I am very interested in VHF &UHF & even SHF. Is there anything equipment wise so far that works well at those frequencies or am I a bit soon? Does the hardware have to cost a fortune? Thanks Ray
