The Terre Haute North Vigo High School (THNVHS) radio club, was formed at the beginning of the 2014 school year with the assistance of the Wabash Valley Amateur Radio Association (W9UUU).  Mr. Jeff Hammers (KD9BHP), the school electronics teacher, began instructing his students in radio theory and practice as part of the electronics cirriculum.  A functioning amateur radio station was set up in November 2014 by members of the WVARA in a spare room adjacent to the electronics laboratory using donated equipment.  HF and VHF Antennas were installed on a 50 ft. tower located immediately outside the school building.  By January 2015, the radio room was repainted and the vanity call sign K9THN was obtained.  The club received ARRL affiliation in 2016, and sixteen students had earned amateur radio licenses by October of that year.



Shown above are students participating in School Club Roundup Contests with instuctors assisting.


Students also enjoy setting up and operating portable as shown here at Shakamak State Park during the 2016 Indiana QSO Party.  This occasion was used to experiment with various kinds of antennas.  A 40M OCF dipole set up as an NVIS antenna performed very well.


The K9THN school station is well equipped with radio gear allowing operation on all bands and modes.  A Ten Tec Orion transceiver can be operated on RTTY and other digital modes with a mouse using the N4PY operating system with MMTTY and other similar software.  All antennas are thoroughly grounded and switchable.


The K9THN station also has a very effective antenna system.  All antennas are mounted on a Rohn tower located immediately outside the radio room.  A renewed top section was installed on the tower prior to mounting antennas.


The base on the 40+ year old tower was refurbished and painted to include the station call sign.

Antennas include: A Rotatable Hex Beam for 20 - 10 M and a four element 6M beam; an OCF Windom for 80 - 10 M; and a 2M / 440 ground plane.


In addition to operating the K9THN station, the students also engage in hands-on learning activities.  Shown here are students replacing the battery in the Ten Tec Orion, working on AZ / EL antenna rotators, setting up a satellite antenna test stand, and downloading a satellite antenna tracking program. 

Shown below is ARRL Indiana Section Manager Joseph Lawrence, K9RFZ, presenting K9THN with the ARRL Affiliation Certificate in April 2016.


The K9THN station is located in the school's Career and Technical Education Center which is equipped with labs and shops that can accomodate almost any project.
