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.

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.


190 repeater OTA

The technical committee announced today that the new repeater has been installed at it’s permanent location on Mercy Hospital, just south of Joplin. The repeater is on 145.190(-) MHz with a PL of 91.5 Hz.


May 2015 Program Meeting / 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.


April 2015 Program Meeting

In April, the club performed a Fox Hunt for the program meeting. A Fox (small, low-power transmitter) was hidden in Joplin, and the members used various techniques to find it. In a previous meeting, the club provided materials and instructions for constructing a 2m loop antenna. This particular antenna has sharp nulls which can be used in finding the direction of the transmitter by turning it until the signal disappears.

Various techniques were used and the winner simply drove around with their HT and listened for the signal to get stronger, then walked around the park until they found David Surgi dressed up like a bum, with the transmitter!


March 2015 Program Meeting

In March the club program meeting was BalUn construction. Jim Scott led the meeting and the club provided materials to construct a 1:1 open air balun by wrapping wire around a PVC core and containing the whole thing in a larger PVC piece. This balun should be able to be used for coax connection to a dipole antenna at lower power levels.

Technician Class in Neosho

I received this email from Dave Boyt, and wanted to pass the info along:

I’ll be teaching a Tech level class at the Newton County EOC (old Armory building 202 W Brook St—2 blocks north of the square) in Neosho this Saturday (March 14th) and next.  We’ll meet from 8:30 to about 4:30 each day.  Cost is $24 for the book (optional, but recommended), and $15 for the exam (no charge for the class itself).  If you know of anyone interested, please let them know.  Anyone who wants to just sit in on the class is welcome.  Advance registration is not required.  Feel free to email or call if you have any questions.
