    MBARC Digital Group Minutes Tuesday Feb 21, 2012

    Introductions.

    Joe got AE7RM (KE7HOK) for a new callsign with his Extra  Congrats also to Kelly, KF7AFF (awaiting new call) and Scott - AE7RO (ex-K7OLF)

     Old business- IRLP repeater has been switched out on King.  The base unit for the IRLP will be located up at the Blaine City Harvey road city-  The city offered free use of the facility with access to the site.  The repeater change was need to make the club IRLP node “play nice” with the IRLP system.  At the last meeting the DG approved payment

     DUES!  Hey, it's almost March and we dropped the dues to a lousy 10 bucks last year.  Pay up.  Roy needs fuel money.


    News and New stuff

    Look at the CHIRP program for radio programming at chirp.danplanet.com  It lets you exchange memory files  between a LOT of different radio makes and models.

    Join the group playing with digital coms with FLDIGI Sunday nights at 2000 hrs on 3582 Khz. There is a new page on the MBARC web site for the Sunday Digital net   http://nwdigi.mbarc.org/.

    Budd Churchward - WB7FHC delivered a fascinating account of his Arduino Morse Code reader project, including a live demo.  Budd's extensive account of the process, with video clips, can be found at http://www.honorlevel.com/data/arduino/readcode/readCode.01.html   and learn about the Arduino at http://www.arduino.cc/

  • Meeting Notes October 2011
    The October MBARC Digital Group meeting was hosted by the Blaine Auxiliary Communications Service who provided a live demonstration of the Winlink-2000 messaging system via HF, VHF, and Telnet.  Thanks Chris - KG6SKO for making the presentation and to BACS members KP2X, KE7NEJ and others who put the time and effort in to setting everything up.  Chris' presentation has been attached to this post in PDF format.

    Other business:  DG-VP Jim KP2X told the group that the plan to relocate the IRLP hardware is going ahead as discussed at the last meeting.  The system will be housed at his QTH where he will be donating the power and Internet connection.  Chris KG6SKO of the Repeater Group will take care of the hardware but we need a member of the Digital Group to assist him on the software management side of the Linux based IRLP system.  Thank you Gary, W7GLC for the many years he has housed the IRLP equipment and provided power and Internet connectivity, and to John KD7PSG who managed the system.  As part of the node upgrade, the King Mtn repeater will be replaced by the Repeater Group to provide a more "IRLP friendly" system.

  • DG Meeting Notes June 21
    The DG met for their final meeting of the season at 1900 local time at the Ferndale Library.  There were @ 14 members present. The first order of business was a discussion of the IRLP node which is currently under the control of the Digital Group.  There have been a number of people misusing the node by leaving it connected and failing to identify.  The node is tied to the King Mt. repeater in Bellingham which is under the control of the MBARC Repeater Group.  It was suggested that control of the IRLP node be ceded to the RG since the node and host repeater need to be managed as a unit.  KC7OAS pointed out that some of the equipment might be privately owned.  Since we don't have enough information to act on the matter at this meeting, and the next meeting will be in September, a motion was made by KC7OAS and seconded by KA0WFI to authorize the executive committee of the DG to take any action they deemed appropriate.  Passed unanimously

    KN0N and WA2TND set up an HF FLDIGI station to demonstrate the robust nature of the Olivia mode.  KN0N forgot his 4:1 balun and ground wire, but WA2TND saved the day by providing a double SO-239 barrel to allow the random wire antenna to be "friction fit" in the center.  With no ground, the outside of the barrel was wired to the iron fence with a piece of rusty stove-pipe wire that was holding a sign up.  The 34 foot antenna wire was stretched at about 6 feet height at a 45 degree angle away from (but below the height of) the iron fence.  The LDG tuner easily found a match and K6IRFin Southern California  responded to our first call on 40 meters.  This was a real poor lash-up that should not have worked, but it did.    Testament to the power of digital modes like Olivia to perform under far less than ideal circumstances.  This demonstration made a few more believers in NBEMS for Emergency Communications use.

    One problem that again arose was the susceptibility of my laptop touchpad to stray RF.  This time we were running only about 20 watts and the antenna was on the other side of a steel wall.  At least one other ham in the group has had the same problem.  Once again WA2TND saved the day by producing a wired USB mouse.  The touchpad on the LT was disabled.


    Andy WA2TND had his NBEMS station running in his truck which he demonstrated in FLARQ connection to his home station on FM simplex.  We tried connecting from inside the library but the metal building was unforgiving.  FLARQ is a program in the NBEMS suite which allows error free conversations and transfers, even to unattended stations.  If you are in the Bellingham area, we are using 145.590 simplex on all digital NBEMS modes.  The hangout on 40 meters is 7065 dial setting with a center frequency in the waterfall of FLDIGI at 1500 Hz.  I hope everyone gets on the air and tries these modes out.  "No place for a decent antenna" is no longer an excuse :)

    Back to business.  KN0N finally remembered that we needed to elect officers for the coming term.  In a truly blinding display of railroading like a rocket-sled; it was moved, seconded and unanimously passed that the same poor Schmucks that held office last term had to do it again.  Honestly, I was still trying to finish an Olivia QSO so I did not catch the particulars.  It looks like KF7AFF will be president, KP2X VP, KC7IJH Treasurer, and KN0N secretary.  By the way, I apologize for failing to mention at the meeting- KD7SDA has been cleaning up a bunch of the links on the web pages.  Thanks Art!

    Meeting adjourned for more chat and radioing.  We take the Summer off from meetings.  See you in SEPTEMBER.
