hi im new to this
i downloaded the digests and i am trying to browns them

i have one question first
i am trying to build a simple gps pll'd ocxo and i want to make shure that
when i loose gps signal the vco signal to the ocxo switch to an manuel mode
or the last vco voltage

my first thogt was a pic that reads nmea and gives a "ok"
thats changes from manual to pll

is this reasonable or is there better ways to do it?
