It was a good test. Lou was glad to hear that some did indeed copy it okay! The observed frequency drifting slightly was expected, due to the large temperature changes in the chamber. In fact, it would have been a challenge to track of the signals over the duration of the test, Lou said, because the RUDAK and spacecraft teams were QSYing around, including many band changes. Stacey Mills, W4SM, P3D Ground Controller, was very helpful in explaining to Steve Greene, KA1LM, and Eric Rosenberg, W3DQ, some of the details of his beta P3D telemetry software. They succeeded in copying the S7-S9 signals from Northern Virginia and Washington, D.C. respectively. Thank you, gentlemen! Thermal-vac stops tonight, with chamber break set for tomorrow morning. The volunteer overnight scheduling has stopped. No more shift work is needed. Thank you to all who rose to the occasion to cover the wee hours, and often multiple shifts! By name: Perry Klein W3PK, Dan Schultz N8FGV, Bill Onuska NI3E, Gary Hendrickson W3DTN and yours truly. Thanks to those in the wings about to cover a shift: Pete Young, K3IN, and Art Feller, W4ART. We are looking for two or three volunteers to meet me tomorrow morning at the chamber to help the team pack up. (Lou would like to start the trip back to Orlando first thing Saturday morning.) To make the security clearances easier, the volunteer overnight "sat sitters" would be a first choice in the packing tasks. Please contact me ASAP to confirm. There were a whole score of AMSAT names from out of town during this test phase that you would readily recognize. See the many team members by going to the P3D Lab web site at <http://www.magicnet.net/~phase3d/>. Check back often to keep track of the P3D spacecraft until it returns for vibration testing in the winter at the NASA Goddard Space Flight Center. An important part of this group was the P3D RUDAK (packet radio) team. Go to <http://users.sgi.net/~hprice/rudaktv.htm> and see some of their outstanding and memorable photos! （JAMSATサイトに翻訳版があります） And don't forget ...
