This discussion group is for people interested in the state of the art of the development of SDR (Software defined Radio) and the commercial, open source and experimental options available to licensed radio amateurs worldwide.
Its purpose is educational and informative.

In this new forum important things can be discussed such as:
What are DUC/DDC (direct up conversion/ direct down conversion) transceivers? Is my transceiver or receiver using that technology? How long has this technology been around and what it's been used for? What companies are manufacturing radios with this technology?
Does Hermes or Mercury, mean anything to you? What about SDR-IQ, Softrock, QS1R or Perseus?
Do they cost more or less to manufacture? Where are they manufactured? Who manufactures them? What is a FPGA (field programmable gate array)? And an ADC (analog to digital converter)? Where are these components engineered and/or manufactured? Does my radio have these devices? Are they important? What do they do?
What are the differences between Open Source software and Propietary software? PowerSDR, SmartSDR, cuSDR, Ham-radio SDR, QTradio and many others…? Who is writing them? What is their history? What radios use them?
What about Gigabit? What is it all about? And all this about sample rates and slices? How do these advances impact the cost of the SDR radio?
Is SDR for everyone?
And, what’s this about client servers?
How much more am I purchasing for $9,000.00? If I already have a $900.00/ 100W transceiver that operates all bands from 160M to 432MHz (70cm)?
How important are these extreme statistics being published by the ARRL and other independent labs?
