[amsat-bb] Re: Why do hamsats? (Or anything else...)

[John B. Stephensen]

Digital signal processing is 40 year old technology at DARPA and first 
appeared on the amateur radio scene 20 years ago. We certainly don't want 
AMSAT to ignore this technology as it can reduce hardware complexity, size 
and power requirements and therefore decrease costs and increase 
reliability.
