History of OSU ARC

OSU Amateur Radio Club (W7OSU) is dedicated to OSU community members who are interested in radio communication.

Welcome to learning more about amateur radio and becoming licensed amateur radio operators!!!

The club's first appearance in Radio Amateur Callbook Magazine was in the summer of 1963 as K7UYX, with this entry:

On the OSU campus, the Army and Air Force ROTC detachments had their call signs (K7NBB and K7NGF) until stopped appearing in the call books after the winter of 1960.

The club kept K7UYX until 1997, then we switched to W7OSU.

Current status of W7OSU

The club station is in Snell Hall 229 where we maintain a club station packed with cool ham radio gear, including:

  • Flex 6300 w/ ATU for HF

  • Kenwood TM-V71 for UHF/VHF

  • Yaesu FT-100 and ICOM IC-706 MkII for all mode portable operation

The club has three antennas on the roof of Snell Hall:

  • Vertical: Hustler 4-BTV for 40-20-15-10 meters

  • Beam: Cushcraft A4S with HyGain CD-45-II rotator system for 20-15-10 meters

  • Dipole: Alpha-Delta DX-CC for 80-40-20-15-10 meters

The club also maintains two repeaters:

  • VHF repeater on 147.160+ (PL 100Hz) located on Vineyard Mountain in McDonald Forest, north of Corvallis

  • UHF repeater on 443.050+ (DCS 032) located on OSU campus

    • As of 2/22/22 the UHF repeater supports C4FM digital

In addition, we have quite a QSL card collection, which is on display in the club room.

General meetings and Bi-Weekly Nets

We are currently planning when we will be meeting Fall term. Stay tuned!

We are starting to have weekly nets on Friday's at 7 pm on the Vineyard mountain repeater: 147.160Mhz. CTCSS: 100Hz

This is our official net where you can hop on, practice radio comm skills, hold practice nets, talk about technical stuff (like a tech net), or just chat about school or whatever is on your mind. A club member will serve as net control. So get your radios and SDRs handy if you want to tune in. Don't have a radio? Tune into our Receiver via Discord channel!

We hope to hear you on the air!

The Benton County Amateur Radio Emergency Service (ARES) holds a net on the Vineyard Mountain Repeater every week.
