Hi Dave,

Good to see you.  Just wondering, are there any GPS applications which 
will croak because of having DCD being pulsed in that manner?  Maybe you 
need a dip switch to turn that signal on or off.  Also, are there other 
applications which expect the pps to be coming though another 
handshaking pin besides DCD?

Sincerely,

Ron
