EQUiSat Optical Beacon CubeSat
by Trevor . 17 Oct '18

17 Oct '18

Students at the Ivy League Brown University are developing an amateur radio satellite EQUiSat that will carry a Xenon Flash Tube (XFT) subsystem to act as an Optical Beacon that should be visible to the unaided eye of observers on Earth.

LVB Tracker USB serial port driver for Windows 7 x64?
by Bill Bordy, NJ1H 22 Dec '16

22 Dec '16

Has anyone located a driver for the LVB Tracker internal USB to serial port adapter on Windows 7 x64? If not, has anyone reverted to the serial port connection on LVB Tracker and used an external USB to serial port adapter successfully with SatPC32 on Windows 7 x64? I have an Edgeport multiple USB to serial port that has drivers for Windows 7 x64 that I will use if I have to. I would prefer using the LVB Tracker with its USB to serial adapter if someone has another solution. 73, Bill NJ1H

AO-16 telemetry 3 Oct 2010
by Mark L. Hammond 01 Jul '16

01 Jul '16

Hi All, Here is a quick AO-16 update. On Sunday I turned AO-16 long enough to get some telemetry packets. The satellite would remain on for less than one minute after being commanded on. A quick test of the "bent pipe" voice mode repeater was successful. . The "hardware watchdog timer problem" is still evident; as expected, spacecraft temperatures are insufficient to keep the transmitter ON (needs to be above 15 deg C). Orbit projections suggest that satellite illumination conditions will not result in increased temperatures for nearly 10 years. Command stations do periodically turn AO-16 "ON" to check on its condition and see if the hardware timer problem has "automagically" fixed itself (which in not anticipated, but who knows...).

CAPE-2 heard in France
by Jean-Pierre Godet 25 Sep '15

25 Sep '15

Dear friends from University of loisiana in Lafayette, Your bird was heard in the North of France when flying over Oran (Algeria), orbit number 204, especially the CW beacon (on 145.823 MHz +- Doppler) between 12:12:52 and 12:13:06 UTC, content was "EUL CAPE 2 OR UF231". The signal was somewhat chirpy, but it's exactly the sound which the real lover of CW like above all. Really ! :-) http://f5yg.pagesperso-orange.fr/forum/CAPE-2_orb204_03dec2013.mp3 The signal to noise ratio is not too good because I'm using an old AM/FM scanner from the 80s heterodyned by my medium wave homebrew transmitter fitted with a 456.9 Xtal. The antenna was a vertical half-wave inside the attic. The next orbit, number 205, was heard too, with the CW beacon affected at that time by a hoarse voice and suffering from a strong fadding. So I'm not absolutly sure, poor lonesome telegraphist, of my human decoding, "M5UL CAPE 2 ÜR 5045", something like that. It was over the East coast of Spain, between 12:12:52 and 12:13:06 : http://f5yg.pagesperso-orange.fr/forum/CAPE-2_orb205_03dec2013.mp3 Congratulation to the Cajun Advanced Picosat Experiment team from France !

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

ISS SSTV July Diploma status update
by John Brier 31 Aug '15

31 Aug '15

They said they would send out diplomas in early August, and since they haven't gone out and it's basically September I asked for an update (while thanking them profusely for their volunteer efforts). This is what I got back: Hello John, I kno, we are out of date. I hope soon we will send diplomas. I'm so soooorrry! 73, Armi You should have gotten an email if you passed the first stage of verification, but I couldn't find mine until I searched my email (subject was "Apollo-Soyuz PASS1verif KG4AKV FM05rv"). You can also see if you are on the list of people who has passed the first stage of verification by searching for your name on the following page (CTRL + F) http://www.arisspolska.info/?page_id=4015 I made it! 73, John KG4AKV
