Are there any #shortwave ham radio operators on Mastodon? (I have to assume there are, but I've never knowingly encountered one!)

@smj
Neat didn't know there was an SSTV thing going on. From ariss.org:

SSTV Event planned for Early August

ARISS News Release                                                                                                       No. 19-12
July 30, 2019

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.

First time my WSPR has made it across the Atlantic, from San Diego! 10678 km on 100 mW (106,780 km per Watt). SNR reported a -17 dB, which is relatively strong, as -20s are regularly seen within NA.

I never knew linux's AX25 package had something like inetd. I may need to dust off my TNC's to play with this.
Around 8min mark Tom explains how you could basically connect most unix programs to packet radio. Connecting an irc client to packet might be fun.

Was talking about Mastodon with an old-school sysadmin guy. We reached the realization that defederating from instances with no/bad moderation is essentially the same thing as blocking open relays back when you ran your own email server: open relays always end up getting used for spam, you block 'em to protect your users.

Email was and still is the first federated social network, so it already faced a lot of the same problems; we should study its solutions (and its failures).
