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...). AO-16 telemetry 3 Oct 2010 1838 utc PACSAT MBL Telemetry Decoder Ver. 1.3 (c) Mike Rupprecht, DK3WN =============================================================================== (average values) +10V Battery Bus : 0.00 V Battery Charge Reg : 0.55 mA Base Temp : 9.07 °C PSK RF Out : 1.90 W +5V RX Bus : 4.87 V +8.5V RX Bus : 8.49 V +10V RX Bus : 11.24 V Here is another teaser :) Several months ago I commanded the AO-16 S-band transmitter ON; it too remains functional (albeit weak), and was received by me, Drew KO4MA, and Alan WA4SCA. 73, -- Mark L.

rx Sirius sat beacons with AIDC3733 converter
by f6htj＠aol.com 24 May '13

24 May '13

In addition: Good reception of sat carriers (+/- 2320.190 MHz) with AIDC3733 2400>144 converter (was modified for AO40 rx): receiver set at +/- 64.190 MHz (instead of 144.190) 73 de Michel F6HTJ ------------------------------------------------------------------------------------------------------ Hello all; for information here in south west Europe we use 2320,100 to 2320,300 cw/ssb portion of 13cm band for tropospheric , AS , RS, traffic. I have been told by Piero I5CTE there is permanent continuous carrier beacon around 2320.190 MHz (+/- doppler) by 1 of the 3 Sirius elliptic NA satellites. It appears reception is very good here with small 20 turn helix antenna (in spite of 12m heliax coax) peaking 539. Apogee (50000km ) around 325deg with 27deg elevation. F5BOF reports same signal with small hand held 25 elements f9ft yagi. So these are for us very interesting beacons. Depending hours we can receive 1 o 2 sats. Real time positions (Sirius-1 / Sirius-2 / Sirius-3) here: http://www.n2yo.com/satellites/?c=33 Any info about beacon sat polarisation and eirp ? 73 de Michel F6HTJ Amsat #7409

The 24-hour timer on AO-07 appears to be working, so it should switch back to Mode A about the same time (10::38:15) tomorrow, 1 January.. 73 Ray W2RS

Since the AO27 website is out of date, what's the latest? There's a 90 degree pass on the next one here for me in WI. Is it working or not? de K9TSU

AC0RA/m
by Wyatt Dirks 30 Dec '12

30 Dec '12

Tomorrow I will be heading north from em21 through several semi-grids arriving back at my home late on the 1st. I am not going strait home so I might be able to work the sats from the following grids em 08/09/11/12/13/14/15/16/17/18/19 and en00/01/10/11/20 and a few more. I am going to try to hit as many grids as I can but due to the long drive times and the satellite pass times I might have to skip a few here and there. Look for me on all satellite passes on the 31st and 1st. Happy New Year! 73 Wyatt AC0RA
