Hermes Interest List Up

TAPR announces the opening of the interest list for the openHPSDR (openhpsdr.org) Hermes single-board SDR. The Hermes interest list is used by TAPR to determine the number of Hermes boards to manufacture in the pending initial production run this spring.

Hermes is a long-awaited addition to the openHPSDR project lineup, advancing through four prototypes while evolving from a USBbased to an Ethernet-based transceiver in about two years. Hermes is a Direct-Down-Conversion receiver, a Direct-Up-Conversion 500mW transmitter and a gigabit Ethernet interface all on one board. Also on board is an RF-quiet switch-mode power supply, allowing Hermes to run from a single 13.8V DC supply.

More information can be found on the Hermes Wiki: http://openhpsdr.org/wiki/index.php?title=HERMES To show your interest, you can sign up here: http://www.hamsdr.com/login.aspx (Note: Look under the Projects tab TAPR-HPSDR link after you log in)
