March Project – Tape Measure Yagi #project

The project meeting next week (Mar 27 at 7p) will be construction of a very portable, collapsible 2m beam antenna using PVC and measuring tape, by Roger Kidd. The club should have enough parts for at least 20 people to construct antennas, including coax, and we will have tools and soldering guns available. These directional antennas will come in handy later this year when we do fox hunts!

The antennas will be built without connectors on the coax – that way you can install the type of end you prefer, such as BNC or PL-259. Of course, if you need help installing that, we will gladly assist you, and the club store does have some PL-259’s for members to purchase.

The club is providing materials for members to build the antennas, while non-members may also participate by purchasing a kit for $9. You can pay via cash or check at the meeting, or via paypal to treasurer@joplin-arc.com any time (just put a comment including your callsign and that it’s for the tape measure yagi.)

2018 Meeting Location Update

After meeting with the officers this week, we decided that the building at 502 S Pearl will be our new meeting place for 2018. The recently remodeled building has a nice large room we can meet in with tables and chairs available, and has on-site parking.

There are entrances on the East and West sides with the handicapped-accessible entrance on the West. You can access the parking lot from either street, or park on the street next to the building (Note that 5th is a one-way going West and parking is on the LEFT on that block)

There are only a few rooms in the building, so don’t worry about getting lost – the meeting room takes up the Northeast corner of the building. See you there Jan 9!

 

EZNEC Training – N8GOU

On the 16th of December 2017 John Frederick, N8GOU, will conduct a 4-hour hands on training session on the Basics of Using EZNEC Software. The session will be broken into these topic areas; general navigation, modeling a simple dipole, modeling a loop, modifications of an existing EZNEC file, creating SWR plots, and finally creating far field plots. After attending you should be able to use the software and begin to explore the more complicated uses of it.

2017 Meeting Location Update

The meeting location for the rest of the year has been confirmed. Starting with the January program meeting on the 24th, all JARC meetings will take place in the Conference Room 2 at Mercy Hospital, 100 Mercy Way, Joplin, MO 64804.

Use the Northeast entrance:

Details on entrance to use for JARC Meeting Location

Do not use the Emergency, Clinic, or Cancer Center entrances. The meeting room is on the 2nd floor. After entering the Hospital, take the elevator or stairs to Floor 2. Turn left toward the Gift Shop, and walk past it. On the right side just past the Gift Shop you will see the conference rooms. Here is a link to an interactive floor map of the facility: map.

2017 Meeting Location

So far, our meeting location for the January 2017 meetings will remain at the Red Cross building. There was a mention at the Holiday Dinner of possibly meeting at a conference room at Mercy Hospital, however we haven’t been able to solidify that reservation at this time.

Voting on Amending Constitution – Online and Nov 8

QST:

If you are a paid member of JARC with an email address on file, you should have received an email this morning with a link to vote on the proposed amendement to the JARC Constitution and Bylaws. The full text can be found here: http://joplin-arc.org/jarcwp/wp-content/uploads/2016/11/Proposed-JARC-Constitution.pdf.
 
Voting will occur at the business meeting on Nov 8, however we are also doing an online vote to try to reach all members. You can either wait to vote at the business meeting or vote online anytime between now and the meeting. Online voting will close 30 mins prior to the meeting time at 7p. I will have a list of those who voted online so we don’t duplicate votes.
 
The reason we are doing it this way is that the current constitution requires a 2/3 vote of all members to amend the constitution, and with our regular meeting turnout, we cannot reach enough people.
 
If you did not get an email and think you should have, please let me know and I can give you login information for the ballot site. Either reply here or email me at K0JAA at ARRL.NET
 
Remember that our annual officer election is also Nov 8, but we do not have an online ballot for that.

April 2016 Program Meeting – APRS

I presented information to the club last night on APRS – Automatic Packet Reporting System, and demonstrated some hardware and software to the club. The presentation is available here in a few formats, for compatibility:

Feel free to use or edit these, and let me know if you have any questions.

Thanks everyone who came and for all the great questions, I had fun presenting and I’m glad to see such interest in this aspect of amateur radio – hope to see more packets on the air in our area!

July Program Meeting

During the July Program Meeting, John Frederick (N8GOU) demonstrated the antenna modelling software EZNEC. This is Windows software that can be used to model all kinds of antennas and then plot the calculated SWR and elevation or azimuth gain for any frequency. There is a free demo available on their website: www.eznec.com.

John modeled a dipole for us and showed the effects of changing the height above ground and the wire diameter, which was very interesting.

Another software that is very similar and compatible is 4NEC2, which is free without the limitations of EZNEC. It can be downloaded here: www.qsl.net/4nec2.
