Invitation – Digital Multiplexing Transponder Working Meeting at HamCation 2020

Open Research Institute is planning a working project kickoff session for the P4XT Digital Multiplexing Transponder Project, and you are invited!

This will be a half-day session to be held just after the closing of HamCation in Orlando on Sunday afternoon, February 9, 2020.

The goal of the P4XT project is to produce open source Digital Multiplexing Transponders (DMTs) for the Amateur Radio Service Microwave Bands, including fully tested and verified hardware, hardware descriptive language, and firmware. These DMTs will be suitable for deployment in Geostationary Orbit.

This will be a working session by the participants. The first half of the session will be technical. The second half will focus on project planning and budget issues.

During the HamCation, there will be a public one-hour high-level presentation of the project. There will also be another one hour presentation by ORI on GEO amateur satellites and a presentation about open source projects across amateur radio.

The written project proposal and the agenda for the meeting will be published in advance of the session.

The session will be held near the HamCation venue. The session will be from 3PM – 7PM on Sunday, February 9, 2020.

3PM – 3:30 PM will be a meet and greet. The formal agenda will be 3:30PM – 7PM.

As this is a working session, attendance is limited. It is not intended to be an open public event but rather a working session of key potential contributors and advisors. Therefore, an RSVP is required.

RSVP to w5nyv@arrl.net or 858 229 3399 (leave a message, texts are welcome)

We will hold this session in accordance with Open Research Institute Developer and Participant Policies. These can be found at https://openresearch.institute/developer-and-participant-policies/

See you there!
