ARVN Presents the
ARRL and TAPR
2009 Digital Communications Conference
6 DVD Set


The 2009 DCC was a three-day conference held in late September near Chicago (same location as the 2008 DCC). It featured seventeen presentations from hams on the leading edge of digital communication and experimentation, including equipment design and construction, Software Designed Radio, AMSAT / ARISSat, packet and D-STAR networking, advanced APRS, and Digital ATV, all available on six DVDs from ARVN.

The six DVDs are organized around common topics. Each DVD has several presentations (details below), and most presentations run about 45 minutes (good for club meeting programs, if your club leans a bit technical).

also available:

You can buy individual DVDs covering the area you're interested in for $15 each (+ $3 shipping), or the whole set for $75 (but still just $3 shipping).  The DVDs are produced in NTSC standard definition video.

The DCC is best experienced "live and in person." There's lot of interaction during breaks, before and after the talks, in the demo room, and at meals - and you get to be the one asking questions. I encourage you to go if you can. The DVDs give you the talks, but not the complete context. I want to thank the ARRL and TAPR, and each presenter, for giving me the opportunity to capture and present the DCC on video - Gary KN4AQ.
