Should you be a part …

Amsat-NA FOX LogoShould you be a part of the AMSAT Community or an AMSAT Organisation?

There are plenty of people who operate on the amateur radio satellites who can identify as being part of the AMSAT community. Many of them are what I’d consider active operators – those heard on passes multiple times in a week or any given month.

The complex question I pose today is “what is the difference between the AMSAT community and the AMSAT organization and why does it matter?”

The AMSAT community of operators isn’t launching satellites. AMSAT organizations with donors and volunteers are launching satellites.

Being active on the birds does not mean you are supporting the AMSAT community. It means you are active in the community as a whole. That’s great. People know your callsign, your name, and have you in their log. That doesn’t get new satellites built and launched. Sending a few emails to the AMSAT-BB or other email lists doesn’t exactly count as volunteering to help the AMSAT organization grow, improve, and make launch goals.

I’m not the most active AMSAT volunteer on the planet. I’ve been trying to do a few hamfests a year, write some Journal articles, keep my membership current, and make an occasional donation. I tend to think every little bit of support helps – no matter what role you play. I encourage new operators to join an AMSAT organization with a vision and a proven track record.

AMSAT-NA is one such organisation. They have successfully launched multiple satellites over their many years of existence. If you are not a member, you should be. That is the “minimum” you should do as an active member of the AMSAT community. If you are located in another region with an AMSAT-affiliated organisation planning a new satellite, join them and get involved. Don’t sit on your duff and brag about how active you are.

Remember, satellites are an infrastructure-based operating environment like repeaters. Infrastructure has an associated cost.

I asked Clayton W5PFG to share his post and he didn’t mind. With this blog I/we hope to inform many amateur radio operators that use the Amsat satellites to think of becoming a member and keep this part of our hobby alive.

Organisation examples: Amsat-NA, Amsat-UK, Amsat-DL, Amsat-SE, Amsat-NL, etc

Dutch Satday 2015

SatDay2013

On April 25th, 2015 an amateur radio meeting (in Dutch: “Interessedag Amateursatellieten”) will be held for everyone who is interested in amateur radio satellites. It will be held in Apeldoorn, The Netherlands. We are very pleased to join this day with the annual VHF day held by the Dutch amateur radio society VERON.

Finally got my PK-96 working

AEA-PK96PK-96 and TS-2000X

After some debugging and measurements, I finally got my PK-96 working with my Kenwood TS-2000X where I use the TS-2000X ACC2 connector. The problem was that when one uses pin 13 PTT the TX audio from the PK-96 is muted. This pin is normally used for a foot switch and not for an external modem. So after I switched pin 13 to pin 9 on the ACC2 connector everything was working. ISS packet here I come.

MASAT-1 deorbiting

Dear Radio Amateur / Masat-1 Packet Committer,

Masat-1 ModelWe would like to hereby thank you for supporting our work in the last almost three years by receiving packets of Masat-1 from space. Furthermore, we would like to call your attention to the upcoming deorbiting. Masat-1, the first Hungarian satellite is expected to end its successful mission by burning while entering the Earth’s atmosphere at the beginning of January (current forecast predicts 11 January). The last days and hours of the satellite are especially important for us, providing valuable data for our upcoming endeavours, therefore we would like to keep a close eye on the satellite during the final stage of the mission. For this, we need the help of all those who have already received Masat-1, as the last moments of the satellite’s life may happen anywhere around the Earth. Who will receive the last packets of Masat-1? Following the final moments we will provide an answer to this question, and we also plan to publish a statistics of those stations who received the highest number of packets during the last 168 hours of the mission.

We have published the current version of the JAVA client software on our website.

Wishing you all the best and Merry Christmas, The Masat-1 Development Team.

ISS SSTV Transmissions

Today december 20 ISS will transmit SSTV images. Below an overview with the passes over Europe. Good luck with receiving the images.

Here is an example that is transmitted by ISS and received by DK3WN last Thursday december 18.
