Ebay's a marvelous place. Well, for remote base use the one he's selling 
is probably adequate. All I was doing with mine was fitting it inside 
the FT-857D, which would be my remote base. I have Micom-2 in the car, 
so I'm all set there. I attached the board layout. The dimensions are 
1.7" X 1.1". I may use surface mount IC's, but keep using 1/0 watt 
resistors so my fingers can still put it together.

Subject: [arm-allstar] Remote base HF squelch
George, I changed the subject on this thread. Great on your experiments. 
By all means keep us informed. I am sure there are many others 
interested in this topic. I would be glad to publish your info on the 
web page when you get to that point. There is a great deal of info on 
the internet on this - google 'SSB syllabic squelch' Also an ebay kit 
but I have no idea how well it really works -
