Heres a selection of articles from electronic design magazine that I think
will be of interest to ham radio operators:

How to get big sounds from small speakers. In recent years, a new
generation of smart amplifiers, incorporating new driver topologies and
digital-signal-processing (DSP) technology allow designers to make big
improvements in both the quality and volume of sound from speakers,
particularly from the very small and cheap units used in many portable
devices. Perhaps hams could do something with this technology to improve
the audio in our radios.Dan
Smart amplifiers include several DSP blocks

PIC microcontroller development tools to developers.

The future of AM radio. Lou Frenzel writes, AM is worth saving; it is a
valuable local community resource. AM radio serves a public safety purpose
for emergency conditions. It provides valuable services to ethnic and
religious populations, as well as high school sports coverage. And still
does a great job of news, weather, and traffic coverage. Talk shows are
also popular. In short, analog still lives. What do you think?
