Föredrag hos SK5UM Flen november 2021

Jag hade förmånen att få hålla ett föredrag om satelliter hos SK5UM Flen i november 2021. SK5UM, som är min “moderklubb” då jag ursprungligen kommer från Flen, är en liten klubb med imponerande utrustning och aktiviteter. De driver flera repeater och en Winlink-station. Dessutom i en egen klubbstuga.

Många intressanta frågor fick jag vilket är extra kul. Åter igen – tack!

AMSAT Board of Directors Hears Various Reports

The AMSAT Board of Directors, including newly elected Board members, met via Zoom on Friday, Oct. 29. The day-long meeting included hearing reports on a vast array of projects and initiatives from officers and team leaders:

  • President Robert Bankston, KE4EL, reported that membersip numbers are holding strong, and that recent administrative modernization has reduced overhead costs by more than 30%.
  • Treasurer Steve Belter, N9IP, affirmed the good news about finances. AMSAT is operating “in the black,” and new electronic systems for handling transactions are working well.
  • VP Development, Frank Karnauskas, N1UW, noted that, despite AMSAT’s solid financial standing, additional funds are needed to design, build, and launch satellites. Thus, an effort to apply for grants from philanthropic organizations and corporate sponsors is underway. He also updated plans for the AMSAT Youth Initiative to launch in early 2022.
  • VP Educational Relations, Alan Johnston, KU2Y, reported on the CubeSat Simulator and High Altitude Balloon projects that have been utilized in classrooms and school amateur radio clubs. Volunteers are being sought to develop lesson plans and curriculum for junior high and high school students.
  • David Taylor, W8AAS, AMSAT Delegate to ARISS-International, updated the Board on ARISS school contacts, classroom lessons and hardware kits, as well as the on-board equipment on the space station.
  • Executive Vice President, Paul Stoetzer, N8HM, reported on regulatory issues, including loss of the 3.3-3.5 GHz band and new leadership at the FCC.
  • Vice-President Operations, Drew Glasbrenner, KO4MA, provided a recap of current AMSAT satellites and their status. It was noted that AO-91 and AO-92 are in the “end of life” mode, and users are implored to avoid accessing these satellites during eclipse.
  • Following a recess for lunch, AMSAT Journal editor, Joe Kornowski, KB6IGK, previewed ong-range plans to move the Journal from Adobe Acrobat format to a fully digital format that would allow live links to resources both on and beyond the member portal.
  • Joe Fitzgerald, KM1P, AMSAT Website and IT Manager, updated the Board on the past year’s transition to a new email platform and highlighted the demands for more expertise as web and IT services become more critical to the organization.
  • AMSAT Contests and Awards, and the AMSAT Store, are both managed by Bruce Paige, KK5DO. Ways of promoting awards and store items were discussed.
  • VP Engineering, Jerry Buxton, N0JY, reported on future satellite projects:
  • Linear Transponder Module currently being provided to the University of Maine for their MESAT1 to be launched next year.
  • GOLF-TEE is under construction and has been added to a launch manifest, tentatively for summer of 2022. Supply chain issues are impacting construction.
  • GOLF-1 is planned for delivery one year after completion of GOLF-TEE. Much about this and future GOLF satellites will depend on what is learned from GOLF-TEE.
  • Orbital Debris Assessment Regulations (ODAR) complicate the design and licensing of the GOLF 3-U platforms. NASA/FCC assessments assume a worst-case scenario in which everything fails. If everything works, the service life of the satellite is drastically reduced.
  • Current projects are stretching the available human resources, and additional volunteers are needed to assist in the building of satellite hardware.

AMSAT Board of Directors Considers Proposals

At an online Zoom meeting held on Friday, Oct. 29, the AMSAT Board of Directors considered a list of proposals. Adopted were…

  • Resolved, that the Board of Directors authorizes the senior officers to acquire a commercially-built FM satellite, including a launch, contingent on funding being received from external sources covering at least 90% of the total cost.
  • To authorize the creation of a working group to evaluate opportunities for a flight to a High Earth Orbit / Highly Elliptical Orbit.
  • That the President be instructed to create an ITAR/EAR/Open Source policy and that he be authorized to expend up to $10,000 for the retention of legal counsel to assist in the effort.

Hardware and "How to..." SDR and software

Guide to AX.25 via OPUSAT-II

OPUSAT-II, or Hirogari satellite, has the possibility to send, store and receive short AX.25 messages. This is a simple guide how to set up a Windows system to send and receive via OPUSAT-II.

  1. Download Soundmodem from
  2. To be able to key your radio, download from the same page and unzip these files to the same folder as Soundmodem
  3. If you use IC-705, download and replace the CAT.DLL file from
  4. Start Soundmodem and set up the ptt for your radio:
  5. Setup the audio input and output to your radio in Soundmodem under Devices menu.
  6. Download MessageBox software from and unzip
  7. Start MessageBox. It should connect to soundmodem.
  8. When OPUSAT-II is in range, transmit via MessageBox (Send) at 436.500 MHz FM and receive at 145.900 MHz. If you are lucky, your AX.25 is stored in OPUSAT-II:
