Behold, Pete KE9OA signalled from keyed 4-1000A filament:

The
boss (software engineer) was working on the interface circuitry over the
weekend, and came along with quite a few ideas. We have decided to add
an RS232 interface to the receiver; this way, folks have the additional
option of computer control. We should have a pretty cool GUI to go along
with it. Stay tuned!

Hi Pete!

Since you and your company have been so kind as to make this project so
open, will us *nix programmers have access to the software protocol so we
can make *nix software to control the RX too?

This is assuming that your boss only plans a Windows interface ;-)

Really appreciate the progress reports!
