New UZ7HO Sound modem version

UZ7HO has released a new version of his great Sound modem software.

UZ7HO Soundmodem

Here is part of the version history file, take a look at this file to get to know al the options.

SCM v0.71b changes:
- Fixed "Frame Collector" operation with MAXFRAME greater than 4 and IPOLL
  frames. By default it supports up to 6 frames into collector's buffer now.
- Added "TXFrmMode" option (that was available in 9k6/19k2 version). It allows
  to select the transmission mode of the frames.

  If set "TXFrmMode=1" then it will repeat only one frame on each of REJ acks.
  It can be useful in poor condition jointly with MAXFRAME up to 4. If another
  station uses a TNC which can operate with "Frame Collector" this option can
  improve a performance, especially on HF.

  If set "TXFrmMode=0" then it will always repeat the block of the frames, of
  which the number is limited by MAXFRAME. It can improve the efficiency in
  good condition. Especially with TNCs without "Frame Collector" function.

  By default this value is "1".

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.

AMSAT-UK LogoOriginal post: Blog W5PFG

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.
