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.

want to have some fun ?
by PA3GUO 02 Mar '16

02 Mar '16

For those that are bored with 1k2 from cubesats .. GRIFEX (437.485) is this week sending data at 19k2 (FM). Quite easy to decode using - 16 element horizontal yagi - SSB preamp + 10 meters Aircell coax - FUNCube dongle (the old one) - SDR# (on Windows 10) - UZ7HO soundmodem (on Windows 10) Remarkable to see how reliable & stable data download can be at higher speeds. With no new investment in equipment ! It may not be for many more days, so give it a try before it switches back to 9k6 (did you try that already?). Henk, PA3GUO

LilacSat-2 FM Transponder
by Paul Stoetzer 01 Mar '16

01 Mar '16

I have noticed that LilacSat-2's FM transponder has been on nearly continuously for the past four days They may be keeping it active continuously during the holiday period in China. It's worth checking out if you haven't worked it yet. It's got a good signal and can be easier to track than SO-50 because the carrier stays active for a period when not receiving signals. The downlink antenna also uses circular polarization, so there is less fading when using linear antennas than on SO-50. Uplink: 144.350 MHz FM (No PL) Downlink: 437.200 MHz FM Keep in mind that this uplink frequency is not within the normal 145.800 - 146.000 MHz satellite subband on two meters, though this frequency is within the 144.300 - 144.500 MHz "New OSCAR subband" in the ARRL band plan and is allocated to the Amateur Satellite Service (as is the entirety of 144 - 146 MHz). On passes over the United States, quite a few packet signals can be heard through the transponder. If you use LoTW, the satellite name to use when uploading QSOs is 'CAS-3H.' 73, Paul, N8HM

DXCC & HamSats
by Rupert Hamblin 01 Mar '16

01 Mar '16

Hi All, I was interested to read the ARRL article on KO4MA receiving the DXCC award worked on satellites, which got me thinking. So here's my question... Taking into account today's available / workable amateur satellites - is it possible for an operator based in the UK/Europe or US, to work 100 different countries via satellite..? (Obviously taking into account the station setup..) Thanks for your feedback ! Cheers RH / G0TKZ

ISS APRS Digipeated Verification
by David Haworth 29 Feb '16

29 Feb '16

I am adding the ISS APRS space communications to the Pine Mountain Observatory STEM workshop this summer. Using the Kenwood TM-D710G with a PC I can show that the packet sent to the ISS was digipeated through the ISS. I would like not having to use a PC with the radio. Therefore, not using a PC is there a TM-D710G setting that will show that the beacon was successfully digipeated through the ISS? QST February 2016 review of the Yaesu on page 52 “ Whenever my FTM-100DR transmitted a beacon and detected that it had been relayed by a digipeater, I hear a series of three descending tones." Has anyone used the Yaesu FTM-100DR APRS with the ISS and confirmed that it will tell you that the ISS digipeated the packet? http://aprs.fi <http://aprs.fi/> and http://ariss.net <http://ariss.net/> work fine if another station receives the packet and forwards it to the APRS Internet System. This depends upon another station which fine for a back up verification. 73, Clear and dark skies without RFI, David Haworth, WA9ONY http://www.stargazing.net/david <http://www.stargazing.net/david> davidahaworth(a)icloud.com
