Hey James,

Now that I have a few more things off my plate, I think it would be a good thing for me to get back to the PSAS project. Let's talk, maybe I should come to a meeting again too! :) See you at the launch?

Hi folks,

Would anyone be interested in attending the 29th Annual ARRL and TAPR
Digital Communications Conference? It's September 24-26, 2010 here in
Portland, Oregon (well, actually across the river at The Heathman Lodge,
Vancouver, Washington). It's good at an introductory level as well as
technical, demo, and seminar levels.

I'd love to spend a little time this summer getting back into the radio
side of the avionics. I suppose it would help for me to start showing up
at meetings. :-)

With the onboard GPS, telemetry, command, backup command, and ATV, the
unique antenna topologies, power and cost considerations and physical
environment demands, our use of radios in PSAS are unusual and
interesting. The conference topics are a fun match: "Software defined
radio (SDR)..., digital satellite communications, Global Position System
(GPS), precision timing, Automatic Position Reporting System® (APRS),
short messaging (a mode of APRS), Digital Signal Processing (DSP), HF
digital modes, Internet interoperability with amateur radio networks,
spread spectrum, IEEE 802.11 and other Part 15 license-exempt systems
adaptable for Amateur Radio, using TCP/IP networking over amateur radio,
mesh and peer to peer wireless networking, emergency and Homeland
Defense backup digital communications, using Linux in amateur radio,
updates on AX.25 and other wireless networking protocols. (pretty much
verbatim from the webpage but I clipped the one phrase about digital voice).

If we can submit an abstract by July 31st, or two, we could present a
paper as well.

Details are at http://tapr.org/dcc.html - let me know if you're
interested in going. For locals this can be really cheap.
