HPSDR Magister


Magister is latin for master. Magister is the master for HPSDR cards residing on the Atlas bus.

Magister performs most of the same functions as the discontinued Ozy. Functions missing are those used to interface to the SDR1000. Complete details on the differences are shown here.

Magister is an FPGA based interface controller card that provides a high-speed USB 2.0 interface for the Atlas bus, as well as limited additional I/O lines intended for radio control (e.g., bandswitching, CW paddle and so forth). It uses the same Altera Cyclone II FPGA as Ozy and is capable of running the current Ozy code (as of 19 September 2009).

The USB interface uses a Cypress FX2 chip, supporting full duplex USB communications at > 30MB/s.

More detailed information is available on the OpenHPSDR Wiki.

Magister Warranty


This is a low volume production, experimental item. TAPR is a small, not- for-profit organization of volunteers who have helped facilitate this project because we believe it is a cool thing to have. In order for TAPR to be able to offer this board at all, we must rely on the support of all users in the HPSDR community.


Support will be provided via the HPSDR Discussion List.

Because TAPR is not staffed to provide support for Magister, and because the knowledge to support users resides with the developers and users on the HPSDR Discussion List, buyers should participate in that forum for support.

Firmware and software will be available for download from the HPSDR website.
