March 01, 2020 To All RADIO AMATEURS BID: $ANS-061.01 Upcoming SpaceX CRS-20 Launch The spouse of ARISS Hardware team member Ed Krome, K9EK, pointed out that the ARISS next generation radio system, the InterOperable Radio System (IORS) is prominently described as a primary payload, not secondary, on the SpaceX CRS-20 mission which will be launched no earlier than March 6, 2020 (ET). The ARISS Team wants to express our heartfelt thanks to everyone that has contributed to helping ARISS realize this major milestone It should be noted that the ARISS hardware team is still very busy on IORS development and final certification. While certified for launch and stowage on ISS, the team is still in deep into the final certification of the IORS for flight operations. Also, the build of the second flight unit is in progress in Florida and in San Diego. While CRS-20 represents the launch of SN 1001, the first flight unit, it also represents the beginning of the "ARISS factory build" and certification of all ten units. The ARISS team also notes that November 13, 2020 will represent the 20th year of ARISS continuous amateur radio operation on ISS!

It will use this mission as an opportunity for undergraduates to get involved in all parts of a space mission, from design to implementation and sustainment. It will test a prototype deployable antenna and solar panels, which can be used for future missions derived from the same baseline design, and with inclusion of additional experimental equipment. It will operate with AX.25 protocol to collect telemetry data. In partnership with the W4AQL Georgia Tech Amateur Radio Club, the satellite will also host a digital contact ROBOT payload, inspired by the Russian ham satellites RS-12 and RS-13. It will collect QSO information from individuals who contact the ROBOT as it orbits. The satellite will also function as a standard digipeater.

The first step was to mount the Yaesu G-5500 el-az rotor system to a Rohn 45 tower. The complete station will include circularly polarized M2 beam antennas for 2m and 70cm, an Icom IC-9700, computers and tracking software. Curt Laumann, K7ZOO, Station Manager for the K7UAZ club reports that Space Camp management is enthusiastic about having UAZ students help with the installation and setup of the station. Student involvement will also include calibrating the rotator system, mapping the artificial horizon for the tracking software and integration and testing the tracking software with the radio. Now in its third year, Space Camp at Biosphere 2 will be held August 3-8, 2020. Space Camp at Biosphere 2 is a joint effort with the University of Arizona Biosphere 2, the Arizona NASA Space Grant Consortium, and the University of Kyoto, Japan. Students attending the camp will experience college-level curriculum and activities focusing on the biological/environmental facets of space travel.

This spacecraft will be a 1U amateur radio CubeSat. It's primary mission is to serve as an FM Repeater and to downlink donor submitted memes via UHF SSTV protocol. MEMESat is also being created to engage people through the sharing of memes from space and help fund small satellite focused research. More information available at https://letsgo2space.com/memesat-1-3/ [ANS thanks Michael Frazier, KJ5Z for the above information.] * Two Commercial Satellites Link Up for First Time A Northrop Grumman robotic servicing spacecraft has hooked up with an aging Intelsat communications satellite more than 22,000 miles over the Pacific Ocean, accomplishing the first link-up between two commercial satellites in space, and the first docking with a satellite that was never designed to receive a visitor. Northrop Grumman's first commercial Mission Extension Vehicle, or MEV 1, will take over propulsion responsibilities for Intelsat 901, which is running low on fuel after more than 18 years in service relaying data and television signals. MEV 1 is the first spacecraft of its kind, and officials say the successful link-up with Intelsat 901 is a harbinger for a new era of commercial satellite servicing. The automated docking early Tuesday also marked the first connection of two satellites in geosynchronous orbit, a region high above the equator where spacecraft move at speeds that match the rate of Earth's rotation.

Re: [amsat-bb] Gulf Alpha Antenna Manual
by Gary 29 Feb '20

29 Feb '20

Congrats on the Gulf-Alpha. I had one and loved it. Built battleship strong, computer optimized, using a Tee-match. Nothing flimsy about it! The only thing I did stupid was sell it when I had to move. If anyone wants to part with one, let me know! 73, Joe kk0sd -----Original Message----- From: AMSAT-BB <amsat-bb-bounces(a)amsat.org> On Behalf Of Gregory Beat via AMSAT-BB Sent: Saturday, February 29, 2020 9:47 AM To: AMSAT-BB(a)amsat.org; nachif(a)terra.com.br Subject: Re: [amsat-bb] Gulf Alpha Antenna Manual In November 2015, Tim Chapman, KB7MDF owner of Arrow Antennas purchased the VHF, UHF and Satellite product lines from Pete, owner of Gulf Alpha Antennas. http://www.arrowantennas.com/ga.html Arrow Antennas may have kept (or posted) documentation for those earlier Gulf Alpha Antennas. http://www.arrowantennas.com/ greg, w9gb == Assembly and Tuning Procedures for 2 meter – 70 Cm Dual band Circular Polarized Satellite Yagi 1. Unpack and separate all parts, UHF, VHF element rods, retaining nuts for the element rods, T matches etc. 2. Assemble the two boom sections, be certain to match up the V half’s which are on the ends of each boom section. Usually this is the only way they can go together. Sections are marked VHF, UHF. 3. Mount the T matches this way: on the 2-meter end the feed point connectors go towards the front of the antenna. On the UHF part, the forward T match is mounted with the feedpoint connectors towards the front of the antenna, the rear T match has its feed point connector towards the rear of the antenna (see pics on our website) 4. Mount the element rods. The longest rod is the reflector, the Driven Element is the ¼" dia. The element rods mount in descending order of length with the reflector being the longest, Install the nuts as you go. Just snug them, do not apply a lot of torque as it is not necessary. Use wrenches if necessary but just snug them only. 5. Slide the shorting bars onto the T match rods and driven elements. Set the distances as follows for lowest SWR: 2 Meter part: 3 ¼" 70CM part: All the way out (this is the setting for other brands of UHF antennas as well) The above distances are measured from the inside face of the shorting bars to the end of the T matchbox, not the end of the black bushing. 6. Install the boom to mast plate just behind the last 2-meter element and in front of the second 2-meter T match. Can hold the antenna at a 15 degree angle (recommended if you do not have and elevation rotor). The V clamps V parts butt against the mast. 7. Install the phasing cables. We recommend looking at the pictures on our website to see how they install. Be certain to deep any cables away from element rods, as that will detune the antennas. Never allow a cable to run parallel to an element rod. == Date: Fri, 28 Feb 20 21:32:01 +0000 From: Luciano Gasparini <nachif(a)terra.com.br> To: AMSAT-NA BB <amsat-bb(a)amsat.org> Subject: [amsat-bb] Gulf Alpha Antenna Manual Some years ago I bought a Gulf Alpha 2m/70cm antenna from the factory.

SatPC32 difficultly switching to CW
by Tom Schaefer 29 Feb '20

29 Feb '20

I am using SatPC32 on my 9700 with version 12.8d. When I click on the CW- option on screen to switch to CW, the radio does not change. Instead, the title of the window changes to 1524 1504. I thought I saw mention of a patch after revision d but the website indicates no patches. I do have a CW entry in the DOPPLER.SQF file. This happened for different satellites all with a CW entry.
