[Laser] Re: Troposcatter and Information Theory-2

[Tim Toast]

i see your point about the simplified circuitry for
sure. And you could always add a filter somewhere to
clean things up if it became necessary someday. It
would be a joy to have to shift frequency for a qso in
progress. i guess marconi didnt worry about key clicks
so much either :-)
I will add phase stability to my list of things to try
and measure when i get going here
