Yes, thanks Andy, for the update. I haven't had a chance to test it extensively, but the sound card selection function seems to work. I selected a SignaLink USB, which was not my default sound card, and a press of the DopplerPSK TX button caused the PTT of the SignaLink USB to key up properly. Thanks, Red KC4LE

DopplerPSK update for PSAT/NO84 PSK31
by aflowers＠frontiernet.net 19 Sep '15

19 Sep '15

I have updated DopplerPSK to v. 0.20. http://www.frontiernet.net/~aflowers/dopplerpsk/dopplerpsk.html 1. A "message loop" feature to aid in QSOs or other experiments where it might be desirable to have a message sent in a loop. The message format and UI is similar to that used in WSJT. Hopefully this is useful for slow typists, especially when fading and/or SNR is a problem. See the new Quick-Start guide for details on how to set up your own messages if the ones provided are insufficient. The original keyboard-to-keyboard mode is still there on another tab. 2. Fixed a couple bugs with saving of station information. 3. Updated the Doppler correction updates to once-per-second instead of every 5 seconds. This should improve tracking on very high elevation passes. In these situations it is critical that your clock be synchronized with UTC as close as possible to minimize residual frequency drift. 4. Added ability to select a sound output device separate from system default. This isn't extensively tested, but those of you who have multiple soundcards for your digital stuff might find it useful. Please let me know of any problems. Andy K0SM/2

Welcome to friends in Harbin - sorry that in July this year I could not visit the space satellite museum on your campus because of refurbishment. 73 de andy G0SFJ

Has anyone seen SatPC32 hang opening a box that says "invalid top level of the document"? and did they find a fix. Thanks Kevin WA6FWF

Short pass, but I monitored XW-2 A, & B on the 00:10utc pass. Nothing heard on CW , 19K2 or 9k6 telemetry. Transponder was not expected to be on. KO6TZ

All, Here are some DOPPLER.SQF values for the upcoming launch. They were done from the initial release of frequencies and other than a cursory check with SatPC32 are obviously unverified.

Re: [amsat-bb] FUNcube-1 operations
by Graham Shirville 18 Sep '15

18 Sep '15

Good evening, I can report that FUNcube-1 was switched back to autonomous mode at around 21:19 UTC this evening. A reminder for next weekend – As AMSAT-UK is holding their Collloquium event in Guildford Surrey, it is expected that FUNcube-1 will be switched to continuous transponder mode , exceptionally, from Thursday evening (July 23rd) until either Sunday evening (July 26th) or, more likely, Monday evening (July 27th). This will enable the Colloquium attendees to view or demonstrate and enjoy the transponder operations for the maximum possible time. Thanks for your understanding! best 73 Graham G3VZV
