The club maintains a radio station and emergency communications center in Building 811R.  The 811R "Ham Shack" is the small modular building located between the two antenna towers.  We recently hosted an open house intended for all Raytheon employees to see the capabilities of our club.  If Raytheon employees would like to schedule a future tour, please send us an email at W7SA-bod@googlegroups.com.

W7SA now has new repeaters on 2m and 70 cm, which are now online and functioning well. They are an open repeaters, so any licensed ham radio operator is welcomed to give it a try.  Any QRM reports related to our repeater should be send to W7SA-bod@googlegroups.com.

All Raytheon employees are welcome to join and participate in CRC activities. For further information, email to CRC Board of Directors, w7sa-bod@googlegroups.com

At this time, local Amateur Licensing exams and classes are offered by the Radio Society of Tucson club (K7RST), OVARC testing, and online (ARRL.ORG and others). The CRC does not currently provide license training, but with your help, we hope to change that in 2025.
