Re: [amsat-bb] ISS-SSTV Aug 1-4 (and PSAT2)

And while you are waiting to see SSTV from ISS, remember PSAT2 also has SSTV. It turns out PSAT2's strings of passes and ISS strings of passes are more-or-less alternating. So if ISS passes are generally in view now, PSAT2's are not. And if you have to wait several hours for ISS, then check and see if PSAT2 passes are in the area. PSAT2 is object number 44354. SSTV downlink is 435.350 +/- Doppler. SSTV is only on when the satellite is in Sun. It helps to keep the PSAT2 transponder up if there is someone also on the PSK31 uplink during the pass on 29.4815 MHz.

ARISS News Release (ANR) No. 19-13

ARISS News Release No. 19-13 Dave Jordan, AA4KN ARISS PR aa4kn(a)amsat.org July 31, 2019 ARISS Next Generation Radio System Completes Critical Flight Certification Tests The Interoperable Radio System (IORS), ARISS' next generation radio system successfully completed a battery of stressful tests required as part of the final certification of the hardware for launch to and operation on the International Space Station. During the week of July 8, the IORS, consisting of the JVC Kenwood D-710GA Radio and the AMSAT developed Multi-Voltage Power Supply, successfully completed a series of Electro-magnetic Interference (EMI)/Electro-Magnetic Compatibility (EMC) tests to ensure that the ARISS hardware will not interfere with the ISS systems or other payloads. Testing continued into the following week, where the IORS successfully passed power quality and acoustics testing. These tests verified that the ARISS IORS will not introduce harmful signals back into the ISS power system and is quiet enough to meet ISS acoustic requirements. ARISS Hardware Team members Lou McFadin, W5DID and Kerry Banke, N6IZW were at the NASA Johnson Space Center supporting this two week battery of tests in concert with the NASA test and certification team. Kerry Banke states, "Since the IORS is being qualified to operate on 120VDC, 28VDC and Russian 28VDC as well as transmitting on VHF or UHF, a lot of test combinations were required to cover all cases. Each input voltage type was also tested at low, medium and high line voltage. Moreover, additional permutations were required to test the IORS under no load, medium load and full load at each voltage level. So it should not be surprising why the tests took two weeks to complete." Successful completion of these tests represents a key milestone in preparing the IORS for launch. ARISS can now begin final assembly of the flight safety certification in preparation for launch. ARISS is working towards launch ready status by the end of the year.

ARISS News Release No. 19-12 Dave Jordan, AA4KN ARISS PR aa4kn(a)amsat.org July 30, 2019 SSTV Event planned for Early August ARISS plans to celebrate the life and accomplishments of astronaut, scientist and ham radio pioneer Owen Garriott with a commemorative SSTV event featuring images from Garriott's work with ham radio during his missions in space. This event is currently scheduled to begin on August 1 at 09:40 UTC and ends at 18:15 UTC on August 4. Please make note that the content of these upcoming SSTV transmissions may change. An update is expected after Friday, July 26 as to what the image content will be for the August 1-4 dates. If this change takes place, the Owen Garriott image transmissions will be postponed until another event can be scheduled toward the end of August. Transmissions will be sent at 145.800 MHz FM in the SSTV mode PD-120. Once received, images can be posted and viewed by the public at http://www.spaceflightsoftware.com/ARISS_SSTV/index.php and you can receive a special SSTV ARISS Award for posting your image. See https://ariss.pzk.org.pl/sstv/ for details. Also for simplicity, we have added a new information tab for SSTV events, under the General Contacts pulldown menu at www.ariss.org . The latest updates can also be found at the ARISS Facebook site Amateur Radio On The International Space Station (ARISS) and on Twitter @ ARISS_status.

CAS-7B (BP-1B) was developed by the Chinese Amateur Satellite Group (CAMSAT), and in cooperation with the Beijing Institute of Technology (BIT). CAMSAT completed the project planning, design, build, and testing, and manages the on-orbit operation of the satellite. BIT provided the satellite environmental testing, launch support, and financial support. Many students from BIT were involved with the project, learning about satellite technology and amateur radio. The satellite carries a CW telemetry beacon and FM repeater that has been active since launch. At the request of CAMSAT and the BIT team, AMSAT hereby designates CAS-7B (BP-1B) as BIT Progress-OSCAR 102 (BO-102). We congratulate the owners and operators of BO-102, thank them for their contribution to the amateur satellite community, and wish them continued success on this and future projects. 73, Drew Glasbrenner, KO4MA AMSAT VP Operations / OSCAR Number Administrator [ANS thanks AMSAT VP Operations / OSCAR Number Administrator Drew Glasbrenner, KO4MA, for the above information.] /EX In addition to regular membership, AMSAT offers membership in the President's Club.

Best APRS software for Windows (and Pi and Android)?
by Ken M 30 Jul '19

30 Jul '19

Hello everyone, I'm seeking suggestions for good APRS client software packages for Windows? There are a number of ancient packages out there but it would be nice to find one that's thoroughly modern and still being maintained. I'm also looking for an APRS client for the Raspberry Pi and maybe Android down the road. What's your favourite? Thanks & 73, Ken VA7KBM
