Amateur Radio Information

SDSMT has an amateur radio club with the call sign KØVVY. If you are interested in becoming a "ham," you can talk with the club president, or perhaps with faculty in the ECE department such as Dr. Batchelder (KBØZND). The club has transceiver and antenna equipment for amateur communications using voice, Morse code and some digital modes. Also, there is a connection in the ham shack to a 40-m dipole antenna that will work very well with your NorCal 40A.

However, to legally transmit with your NorCal 40A, you must first obtain your Technician's license and pass a five word-per-minute Morse code exam. (Of course, no license is needed to receive.)
