Radio spectrum is a finite resource and it should therefore come as no
surprise that radio systems are a particularly hot area of research. Whilst
ever more advanced schemes for modulation, digital encoding and spectrum
access promise increased efficiency, step upgrades more often than not
require new hardware. As has been evidenced in the evolution of mobile
telephony from analogue to GSM and 2.5G (GPRS) to 3G, and similarly in the
evolution of wireless computer networks. A disruptive development in radio
technology promises to change this and to bring an unprecedented flexibility
to radio systems, and one similar to that which programming brought to the
task of machine computation. Despite, or perhaps due to being at the cutting
edge there are a number of open source hardware projects concerned with
developing software-defined radio (SDR) technology. As with the earliest
developments in radio systems radio amateurs are once again at the
forefront, and at this month's meeting we will have a presentation on the
comprehensive HPSDR platform.

// HPSDR - High Performance Software Defined Radio //

HPSDR is an open source (GNU type) hardware and software project intended as
the "next generation" software-defined radio for radio amateurs and
shortwave listeners. It is being developed by a group of software-defined
radio enthusiasts around the world, and in a modular hardware fashion to
help promote experimentation by both hardware and software developers.

John Melton has held an amateur radio license since 1984 when he was first
licensed as N6LYT while living and working in California, and he was
assigned the UK callsign of G0ORX on moving back to the UK. He became
interested in developing open source software in 1990 with the launch of
AMSAT Oscar 16, an amateur radio satellite with a store and forward
messaging payload. He developed an open source software package to
communicate with the satellite that ran on Linux (pre 1.0) and subsequently
wrote an open source fully automated satellite ground station software
package in Java. John has been a software engineer since 1970 when he was
employed by Burroughs Corporation, and for the last 14 years he has worked
for Sun Microsystems who were acquired by Oracle this year.

// Open Discussion - Ideas for Future Meetings //

Themes, speakers, venues - it's all up for grabs! Have your say and help
shape future OSHUG meetings. Offer to present, suggest a speaker or sit
quietly until it's time to cross the road to the pub...
