Jim 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:

Support for the CAN-Do! command bus interface was provided by Stephen, KC0FTQ. For more information check out EaglePedia:

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".
This week the first prototype of the Eagle satellite 70cm receiver became operational. Juan Rivera, WA6HTP and team moved from troubleshooting to testing mode. The receiver was on display in the AMSAT booth at Dayton. Be sure and check out all the design, peer review, troubleshooting testing and operational areas of the U-Band Receiver on EaglePedia to see what it takes to produce a piece of the Eagle satellite.
Juan wrote, "Look for more details on my blogs on EaglePedia. 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!"
