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.
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:
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.
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.
Our recent project has been a direct conversion design and build, presented by John Frederick and Jim Scott. See below for the details on the project:
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:
- APRS – K0JAA 2016 – PowerPoint 2016 pptx file (17MB)
- APRS – K0JAA 2016 – PowerPoint 97-2003 ppt file (18MB)
- APRS – K0JAA 2016 – OpenDocument Presentation odp file (17MB)
- APRS – K0JAA 2016 – PDF file (2MB)
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!
This month’s program meeting (tomorrow night) will be covering the use of LOTW, the incoming and outgoing ARRL QSL card bureau, and eQSL. John has put together the attached handout for further information and links:
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.
This is a reminder that there is no program meeting this month – the June 23rd meeting is cancelled since Field Day is the same week. Hope to see you all at Field Day!
Field Day is coming up in just a few short weeks!
June 27th and 28th from 1800Z to 1800Z, Joplin ARC will be set up at Dover Hill on North Main Street in Joplin. The club will operate as Class 3A, using emergency power and will have 3 operators on all HF bands and possibly VHF and UHF.
The club will supply 2 tents, restroom facilities, and will have a cook out. One tent will be for operating and one for socializing. Bring your own chair and bug spray!
We plan on logging using N3FJP software, so if you are supplying a laptop, please install that and contact the club to get a key.
Setup will be Friday afternoon so anyone interested, please come out and get involved.
