Re: [IRCA] Elad FDM-S2 initial testing

[Nick Hall-Patch <nhp@xxxxxxxx>]

Thanks for posting this Mark.   What 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
