Get Involved

Joining HamSCI

Welcome to the HamSCI community! We are a group of amateur radio operators and scientists working together to study the ionosphere and further the amateur radio hobby. If you are completely new to amateur radio and ionospheric science, take a look at the ARRL's What is Amateur Radio page. That is a great place to learn how to get your amateur radio license and learn the basics for participating in the HamSCI community.

HamSCI consists of many different types of projects accessible to a variety of skill levels. Some are more science focused, some are more engineering focused, and some are more focused on the amateur radio hobby. The best way to get involved is to join some of the mailing lists, participate in the telecons, come to the annual HamSCI workshop. You will meet other people in the HamSCI community that can help you to find a project that best matches your interests and skill level. Have a question? E-mail Nathaniel W2NAF at

HamSCI Google Group

Participate in the HamSCI Community by joining the HamSCI Google Group. The HamSCI Google Group is an e-mail discussion forum to facilitate communication between hams, the professional space and atmsopheric science communities, and anyone else interested. When requesting to join, please include some information about who you are and why you would like to join. Particpation is governed by the HamSCI Community Participation Guidelines. This group is moderated by Nathaniel Frissell W2NAF, Kristina Collins KD8OXT, and David Kazdan AD8Y.

Grape PSWS Google Group

The low-cost version of the Personal Space Weather Station is known as the Grape, and is being developed by Case Western Reserve University. If you would like to participate in the Grape portion of the project, please join the HamSCI-Grape Google Group.

TangerineSDR TAPR Listserv

TAPR (Tucson Amateur Packet Radio) is an amateur radio organization dedicated to electrical engineering. TAPR has teamed up with HamSCI to design and build portions of the HamSCI Personal Space Weather Station, including a new software defined radios (SDRs) known as Tangerine and Clementine SDRs, as well as the ground magnetometer module. If you want to be a part of HamSCI's SDR and ground magnetometer engineering work, you should join the TangerineSDR listserv by visiting The TangerineSDR listserv is administered by TAPR and is more engineering focused than the HamSCI Google Group.

HamSCI Science Telecons

There are currently three regularly scheduled telecons to support HamSCI work. All are open to the public, please see the calendar below to confirm teleconference times and view conference call connection information.

  1. TAPR-HamSCI Technical Session: Weekly telecon hosted on Mondays at 9 PM Eastern (Tuesday 0100z) by TAPR and The University of Scranton to support collaborative HamSCI-TAPR projects.
  2. Grape Low-Cost PSWS Telecon: Weekly telecon on Thursdays at 10 AM Eastern (1400z) hosted by Case Western Reserve University to support the Grape Low-Cost Personal Space Weather Station Project.
  3. HamSCIence Telecon: Weekly telecon on Thursdays at 4 PM Eastern (2000z) to discuss data collection, analysis and conclusions related to HamSCI's scientific research efforts.  All backgrounds, including researchers, data analysts and citizen scientists, are welcome and encouraged to attend.

Archival recordings of HamSCI and ClementineSDR/TangerineSDR telecons are available here.
