request for telemetry recording during X-CubeSat orbital decay
by Jean-Pierre Godet 03 Feb '19

03 Feb '19

Jean Guérard, from the french national aerospace research centre ONERA, is requesting to all who as the opportunity, please, to record the last telemetry frames of the bird launched in May 2017 by the polytechnic school (in Palaiseau, France). X-Cubesat is expected to decay around Mon, 04/02/2019 10:58:00 +/- 7 hours UTC (these predictions are provided by Joseph Remis, expert in satellite reentry predictions from the International Astronomical Center). The frequency is 437.020 MHz (measured here 437.01792), modulation AFSK 1k2, mode AX25. Warning, the fresh tle are already not too good, but anyways... Please, send information directly to Jean Guérard, jean.guerard(a)saf-astronomie.fr Many thanks my friends, have a good Sunday, 73 ! Jean-Pierre F5YG

ARISS News Release No. 19-02

ARISS News Release No. 19-02 Dave Jordan, AA4KN ARISS PR aa4kn(a)amsat.org Announcing ARISS/NOTA Slow Scan TV Event Feb 2, 2019: ARISS is planning another of their popular Slow Scan Television (SSTV) experiment events. Transmissions are scheduled to begin Friday, Feb. 8 at 18:25 UTC and run through Sunday, Feb. 10 at 18:30 UTC. SSTV operations is a process by which images are sent from the International Space Station (ISS) via ham radio and received by ham operators, shortwave listeners and other radio enthusiasts on Earth, similar to pictures shared on cell phones using twitter or instagram. When this event becomes active, SSTV images will be transmitted from the ISS at the frequency of 145.80 MHz using the SSTV mode of PD120 and can be received using ham radio equipment as simple as a 2 meter handheld radio or a common shortwave or scanner receiver the covers the 2 meter ham band. After connecting the audio output of the radio receiver to the audio input of a computer running free software such as MMSSTV, the SSTV images can be displayed. Transmissions will consist of eight NASA On The Air (NOTA) images (see https://nasaontheair.wordpress.com/). In additional, four ARISS commemorative images will also be included. Once received, Images can be posted and viewed by the public at http://www.spaceflightsoftware.com/ARISS_SSTV/index.php . In addition, you can receive a special SSTV ARISS Award for posting your image. Once the event begins, see details at https://ariss.pzk.org.pl/sstv/ . Please note that the event is dependent on other activities, schedules and crew responsibilities on the ISS and are subject to change at any time. Please check for news and the most current information on the AMSAT.org and ARISS.org websites, the AMSAT-BB(a)amsat.org, the ARISS facebook at Amateur Radio On The International Space Station (ARISS) and ARISS twitter @ARISS_status. About ARISS Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in space (CASIS) and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org.

Mike, I don't see any times listed for the Amsat tracking. I think the problem is people are saying that HRD "lags" (ie, the track is correct, but several seconds/minutes behind). Regardless of if that is true or not, what I would suggest to verify HRD's tracking is to open two windows, one with AO-91 or 92 in HRD (realtime, during an actual pass), and one with Amsat Argentina's website: http://amsat.org.ar/pass.htm Be sure to enter your correct grid square and select the correct satellite, and it will tell you current Az/El and doppler frequencies for Uplink and Downlink. I've found this site to be very reliable, and no installs are required (it runs in the browser). --Roy K3RLD ------------------------------ > Regarding the control of two VFOs simultaneously... we're working on this > next.

FM radio suggestions?
by Ron VE8RT 02 Feb '19

02 Feb '19

GM, I have a friend in an isolated community working on passing their Canadian Basic Amateur Radio Licence. If they pass with honours they'll have access to the HF bands, otherwise they're restricted to VHF and up. To start them off I was going to suggest getting on the FM satellites. I would also like to upgrade my satellite gear to include digital capability and thought I'd look into getting a second of the same radio, easier to mentor them at a distance if we're using the same gear. The model of interest is the FT-8900R and I'm open to suggestions. And I was thinking of ordering a printed copy of Getting Started on Amateur Satellites 2018 to be sent to them. For myself, I'd like to explore digital satellites, APRS and store and forward, are there current (quite a few out of date ones have turned up) website for beginners? Thanks, Ron VE8RT DP22 -- Ron VE8RT <ve8rt(a)yknwt.ca>

Gpredict on Raspberry Pi
by Paul Overn 02 Feb '19

02 Feb '19

Playing around with gPredict on the R-pi. Wondering how to add another location for TLE files? The Rpi version does not have the "add TLE" option in the TLE screen. So it looks like I'm stuck with only the one TLE location. I'm specifically trying to add AO-85, but I'm sure there are others.

XW-2A and Other Roads Less Travelled
by Les Rayburn 02 Feb '19

02 Feb '19

I’m a bit of a nomad, and have always enjoyed taking the roads less travelled. That applies to my hobby as well—those of us who work VHF are a fairly rare bunch. Those who work satellites; not often spotted in the wild. But apparently, rarer still are those who enjoy making contacts on satellites that are not AO-91, A0-92, SO-50, and FO-29. Working from home today, so I got on nearly every satellite pass over the United States. Alternated between calling CQ and searching for others to work. The results of working eight different passes? Four contacts for the day. Two on SO-50, one each on AO-91 and FO-29. Called CQ on XW-2A at dinner time. High elevation pass. Good strong downlink the entire pass from horizon to horizon. Nada… It did net me an SWL report from Mark Gluch, KB3CI who heard me loud and clean in EN82 near Detroit. He doesn’t have the transmit side working yet for the linear birds, but will soon. Ditto on AO-7, a whole pass on FO-29 this morning, and at least three of the XW birds. Last weekend, I listed to the L band activity on AO-91 and there was a ton more activity there than I heard today. (I’m working on getting the 1296 Yagi up so I can join you folks.) We’ve got a sky full of great satellites that perform well. Let’s use them. 73, Les Rayburn, N1LF 121 Mayfair Park Maylene, AL 35114 EM63nf Member WTFDA, IRCA, NRC.

SDRplay RSP2pro test antenna?
by Ted Krempa 02 Feb '19

02 Feb '19

Hi Just got around to install with SDR Console and will be playing around with the Satellite portion. Question: for testing on rx, would a discone or dual band vertical work best ? (before I set up the real antenna - Elk on a rotor) Any input appreciated 73, Ted K7TRK
