Too many things happening.

Please visit this link to see the Flex Radio Archives (this is a blatant attempt to get Google to index it).

Since my last posting I have been so busy I could barely keep my head above water. I began a white paper on AMSAT's new spacecraft. I have interviewed 51 applicants to Brown University (my alma mater), written major new pieces for Flex Radio's PowerSDR , starting bringing together the changes needed to release DttSP version 2.0 (not yet released) with AB2KT, and completed the stereo FM demodulator/demultiplexer for GnuRadio . WHEW. Sorry for the delay in getting this up. I will have a lot more to write about all of this soon.

WSJT 6 work

I have begun helping Joe Taylor, K1JT, author of WJST in an effort to port WSJT to Linux, and to add a GPL version of the soft decision Reed Solomon decoder so we can remove KSVAD (a licensed and proprietary and closed source decoder).

Please check out a short pdf of the work so far: wjst.pdf

This work is being done by a group of people and the work is being shared with svn on a server.

Stand by for more.

December in Marburg, Germany

I spent two working weeks in Marburg Germany with Karl Meinzer at Phillips (Marburg) University in the ZEL ( Zentrale Entwicklungslabor für Elektronik).
