DCC Day Two - Bidirectional Low Frequency Transverter

Alex Schwarz, VE7DXW - Bidirectional Low Frequency Transverter (Bi-LIF) Computer Interface for Demodulation and Modulation of Radio SIgnals

Alex outlined a Software/Hardware system that allows you to use current or older HF gear with an SDR based replacement for the original mod/demod section of the rig.

Essentially what he's doing is tapping into the receiver IF and using SDR techniques to provide demodulation on receive, and also tapping into the transmitter section to modulate.   Couple this with PC software to control the radio and do the mod/demod and you have some of the benefits of SDR applied to older radios.

Boards and kits available.

DCC Day Two - WINMOR Phase 2

Rick Muething, KN6KB/AAA9WK - WINMOR Phase 2: Demonstration to Deployment

WINMOR (WINlink Message Over Radio) is a replacement for the proprietary Pactor protocols in Winlink networks.  It uses standard PC's and soundcards to impliment an ARQ protocl that approaches Pactor 2 and 3 in performance yet is freely available and can be implimented anywhere on any OS.

DCC Day Two - RMS Express

Victor Poor, W5SMN/AA9WL - RMS Express - A Multimode Winlink 2000 User Client Progrom

Victor gave a talk on the Windows based RMS Express client program for the new WINMOR protocol.

While I'm not personally all that interested in Winlink, the discussion of why RMS Express was designed was interesting. 

RMS Express is designed to be easy to use, quick and foolproof to install (as Victor said "at least fool resistant")

Interesting features:

  • Automatic HF channel list updates - list current HF channels that are in use worldwide
  • HF Propagation prediction sorts the list by most probable frequency to make a given connection
  • Control for most common HF rigs in current use
  • Not a peer-to-peer or keyboard-to-keyboard program with the exception of it's use with the WINMOR protocol
  • The GUI interface looks a lot like a typical email client. ( A beef of mine about all these various Amateur Radio programs, why not make these systems use your real email program?)

Last two talks of the day

I skipped a couple of the early afternoon talks but was back for the last two of the day.

My netbook battery was exhausted so these are from memory and the DCC printed proceedings.

Robotic Radio and CW Robot

Rob Frohne, KL7NA on a building block for Robotic radio

Nice dig by Rob on the age profile of his audience :-)

Using Robotics (Lego robots) to reach kids and encourage Ham Radio.

Robotic Radio - Doing things automatically that we as operators used to do.

  • SteppIR's antennas for example
  • Automatic antenna tuners
  • Rotators
  • pskreporter.info
  • WebSDR - SDR receivers online,  websdr.org

Rob gave a little intro to Open Source software for radio,  FLDIGI, DTTSP, SDR-Shell, etc.

 

CW Robot is an opensource version of CWSkimmer written by Rob's Students and is available at:

http://people.wallawalla.edu/~Rob.Frohne/CW-Robot/cw-robot.tar.gz

Check out http://www.websdr.org and follow the link to K7UEB, Walla Walla university to play with Rob's setup.

2010 ARRL and TAPR Digital Communications Conference

This weekend is the annual ARRL/TAPR DCC and it happens to be close enough (Vancouver,WA) that a contingent of WETNET folk are attending.

SIx of us came down on Amtrak Thursday evening and we'll be posting pictures all weeking.  I might even find time to post a few articles as well

Yup, Wetnet was down

I messed up Wednesday (no I don't want to talk about it :-) and the server didn't come back from a reset. 

Rather than rush over to Isomedia and bring the box back up immediately I took the time to gather the materials to fix the RAID array problem we've had for some months.

On Thursday morning I replaced the bad drive, fixed my foobar and brought the system back up.

We're up and running at 100% for the first time in months.

Options for High-Speed Packet: 2010 Edition

(With apologies to Barry McLarnon, VE3JF who wrote the original Options for Medium to High-Speed Packet in 1993)

Periodically, certain well known and notorious members (you know who you are) of WETNET have gathered to discuss the if, why and how packet radio activity might be made to grow, particularly in the Pacific Northwest. The arguments regarding "if" and "why" are far too controversial to continue discussing here, but let it suffice it to say that there seem to be two opposing views:
