Hi all, is there an OS X version of wsjtx-1.7.0-devel
<http://physics.princeton.edu/pulsar/K1JT/wsjtx-1.7.0-devel-Darwin.dmg>
available yet?…I have found the 1.7 user manual that provides a link but i get
a 404 when i click on it…I see its of folks using the Windows and Linux
versions on PSK reporter…Thanks
