Welcome to the website of the Joplin Amateur Radio Club.  If you would like to find out more about the club, look around the site (use the menus at the top) and drop in to any of our meetings or nets.  If you are not yet a licensed ham, we also offer VE Testing.  All amateur radio enthusiasts are welcome at our events, member and non-member alike.

The club also sells antenna launcher kits which are put together by club members right here in Joplin, MO, USA and can be shipped anywhere.  These are great for putting up antennas either in your yard, or at a Field Day site!

Feel free to register on this site – if you are a member, this will give you access to the member’s area, but non-members can also comment on posts.

Rt 66 OTA 2015

The JARC will be participating in the Route 66 On the Air special event again this year, as W6N. The event runs from Friday, Sept 11 starting at 7p CDT to Sunday, Sept 20 at 7p CDT. We encourage club stations to operate on SSB, CW, and Digital modes on the following bands: 80, 40, 30, 20, 17, 15, 12, 10, and 6M.

Jim Johannes will be coordinating the event and a sign-up has been created here: www.SignUpGenius.com/go/10C0F45ACAE28AAF49-rt66ota. Please put your Name and Callsign in the Name field, and indicate which mode you plan on working. There is only one slot created per band per day – you are not expected to work the entire day, coordinate with Jim on when you will be on the air.

If you decide to work as W6N please text Jim when you do – his number can be found in the club roster which is sent via email monthly, or located on the club members page.

More information about this event can be found here: w6jbt.org.

Kansas QSO Party 2015

Members of the JARC set up in Schermerhorn Park south of Galena, KS and operated as K0T on August 29-30. The special event station made approximately 150 contacts, most of which were out of state. They tried a lot of antenna configurations with varying success but reported it was a fun exercise and chance to experiment and get on the air. For more information about the KS QSO Party, check out their website: www.ksqsoparty.org.

Joplin Hamfest 2015 Report

The Joplin Hamfest was held on August 21-22 this year – it was the 26th time the club has put on the local hamfest. The Hamfest Committee did a lot of work organizing the Hamfest, and it showed, they did a great job and we only heard positive feedback about the event! Now that the numbers have all been tallied, we had over 1,000 attendees, including public and swap table vendors.

Despite torrential rain and flooding on Saturday, we had a good turnout, and there were 3 presentations in the Joplin Hotel next door. We gave out many great prizes in the drawing, including a grand prize of a complete HF station to one lucky winner.

Thanks to all who attended, and hope to see you back next year!

Photos will be added to an album and posted soon. If you have any photos of the Hamfest you’d like to add to our page, please email k0jaa@arrl.net.

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.

Field Day 2015 Report

The 2015 Field Day event was a great success for the Joplin Amateur Radio Club. We logged around 1060 contacts on SSB, CW, and PSK31, had many visitors including 2 elected officials, and enjoyed delicious food cooked by our club members. The weather was nice for both days and we put up quite a few wire antennas and a few beams for 2m and 6m. We also got to try out our new generator which worked very well and only used about 2 gallons of fuel.

Photos of the event are being consolidated into an album and will be posted here soon.

June Program Meeting

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!

DXCC Prefixes

Jim Scott recently emailed a list of call sign prefixes out for use in operating. I thought this was a great, handy resource, however it was saved at a low DPI that made it hard to read – I did some searching and found a list on the ARRL site and made a similar, newer version. This may come in handy for Field Day or other contests, DXCC, or just your day-to-day operating to see where that strange call is from.

The current version I’ve created can be downloaded here: prefixes v2.

Web Site Updates

The web site theme has been updated to help with navigation on small screens, please let K0JAA know if you have any problems with the new layout.

The meeting minutes from the June Business meeting are now available in the members area, along with a new page listing all of the supplies that the club has in stock to sell to its members.

I have also updated the site with posts and photos from the March, April, and May program meetings, which are in the news feed, or linked on the meetings page.
