[amsat-bb] Fox Delta ST2 with G5500DC? [SOLVED]

[Burns Fisher]

Thanks, Ben.  Good info!  So you think Yaesu changed the pinout between the
AC and the DC versions?  Annoying!

 I know that a number of people have used the ST2 without issues.  And that
is pretty much a clone of the LVB Tracker, which I use with no problem.
