The MIT UHF Repeater Association

W1XM


Spring 2025

W1XM is regularly meeting and working on building out the station! Interested MIT students should email w1xm-officers@mit.edu for info about joining the club. No experience is required, both grad and undergrad members interested in communications, radio, electrical engineering, radio astronomy, and networking are welcome. Some current projects include hydrogen-line radio astronomy using the big dish in the radome on building 54, designing power amplifiers for the VHF/UHF/microwave contest station, and various Software-Defined Radio projects.

Radome

The giant white sphere on the roof of the Green Building (building 54) contains a radar dish used for a mix of radio astronomy, satellite communications, and amateur radio. Scheduling time on the dish happens through this Google Calendar.

Activities

We do experimentation and contesting with new amateur radio technologies. The renovated station includes many software-defined radios and will cover the 23cm, 1.5m, 2m, and 6m bands. Non-amateur radio activities connected to the club include radio astronomy, satellite communications, and ionospheric research.

The MIT UHF Repeater Association maintains the W1XM Repeater which is located on the top of the Green Building.

449.725 MHz (-5 MHz offset)
114.8 Hz CTCSS

In addition to the Repeater, the MIT UHF Repeater Association also has a station (or "Shack") on the roof of the Green building which is used for VHF/UHF contesting purposes. The new station has been operational in several contests over the past year.

Interested students should come to our weekly hangouts in 50-357 from 7-10 PM. Additionally, business meetings are held monthly. All MIT students are welcome and food is usually served. No previous radio experience necessary.
