    I have been using the radio shack "atomic clock" for quite a while with SDR.
What might be the advantage of the GPS clock? The price is right for the radio
shack unit but maybe there is a problem with reception. Would the GPS unit be
more compatable with file transfer via pcanywhere and it's interupts?
Regards
Barry
