Re: [IRCA] Elad FDM-S2 initial testing

--- Begin Message --- 
As I have been learning, the challenge may be also traveling with a suitable broadband antenna in order to realize the benefit of an SDR. The DXers who travel by car to sites, such as Rockworks have more options regarding what they can pack than those flying out to the coast. Just a thought.

 Thanks for posting this
 Mark.ÂÂÂWhat were the capabilities of the 
 computer used to run the two pieces of software?
 
 The Elads and some of the more recent SDRs are physically
 quite 
 small, so can be used on hiking trips or other travel where
 not much 
 luggage can be taken along.  But, it's good to
 be able to use a 
 correspondingly small and power sipping computer under such
 circumstances.
 
 best wishes,
 
 Nick
