Eagle prototype UHF receiver powered up, testing commencesJim Sanford, WB4GCS, Eagle Project Manager, has good news this week. Jim reported the completion of construction of the first prototype of the Eagle 70cm Uplink Receiver. The receiver has been powered up with testing and evaluation starting on May 5. The receiver was designed by John Stephensen, KD6OZH. Juan Rivera, WA6HTP and the Project Oscar Team implemented the design and produced the first prototype. Juan and John have provided extensive documentation on the receiver design and construction which is available on AMSAT's EaglePedia. See: http://www.amsat.org/amsat-new/eagle/EaglePedia/index.php/U-Band_Receiver Support for the CAN-Do! command bus interface was provided by Stephen, KC0FTQ. For more information check out EaglePedia: http://www.amsat.org/amsat-new/eagle/EaglePedia/index.php/Category:CanDo John described his receiver design, "This is a key component of the Mode B linear transponder and provides higher dynamic range than Phase 3 satellite receivers. Our 70 cm band is shared and this minimizes interference from the military radiolocation service and provides improved performance for users in the amateur radio service". Juan wrote, "Look for more details on my blogs on EaglePedia over the weekend. My special thanks to everyone who made this possible. It was a team effort from beginning to end." Jim concluded, "I wish to express my thanks and gratitude to the entire team for reaching this significant Eagle milestone!"
Jim, WB4GCS
