Pete,

How far can you detune the input signal before losing lock on the sync'?
What is the capture ratio?

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!

Pete

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!
