With a low cost GPS module (and they are becoming very cheap now !) anyone can
get a 1 pulse per second signal accurate to within a microsecond of UTC.  Which
makes all the usual requirements for decoding coherent transmissions such as
clock and carrier recovery redundant.  


This, as always from Andy, is a good idea. But, is it possible to use the data output stream from the standard Garmin etc GPS units? A number of us have eTREX and other units in our cars and it would be a much more appealing excercise if it were possible to make these 'dual use' and not to have to invest in another module.
I have looked around for the 'cheap' modules, as I quite like the idea of a locked reference for my frequency counter, but they seem to be phantoms of the night. - Always just sold out or not cheap at all.
