Tickets are $10.00 until Expo opens, then $13.50 until April 10th: Check out the topics, including a hearham.live demo!

Machine Learning, math and other cool tricks
A previous posting showed how to set up Winlink through basic internet (Telnet). Internet/Wifi may or may not be available in any emergency, however, so it is important to be able to work Winlink over a VHF/UHF radio – which is the main benefit of WINLINK over e-mail, after all. To get this working you will need a radio, a TNC, and computer with the Pat or Winlink program. For my test I use a Yaesu FT-70 handheld, Mobilinkd TNC3, and Pat on a Linux computer.

Some previous app ratings suggested that this was “not real”, but it is in fact a real card – it has been delayed but the card production issues apparently were figured out, as they are shipping now.

Have you ever lost one sock or one shoe after looking all over for days or weeks? Well don’t feel so bad, recently some scientists found their second ski at a research site after the ice melted for seven years!
