Besides winlink there are additional ALE (automatic link establishment)
systems, one of which
will be running a world Wide interoperability test for 10 days starting March
27. Details and
channels (there are 19 listed) used are at
http://hflink.com
If you're unaware of ALE systems here's a quote from the website
The innovative ALE system is a digital selective calling method, enabling radio
users to ring each other up on High Frequency shortwave using their callsigns
like a phone number.
Over three thousand ALE stations have registered so far, and many of them are
on-the-air this week talking by single sideband (SSB) analog voice or digital
texting.
