I have a Shera style GPS box and I agree with Jay. My RX is GPS
locked and I would love to be able to lock Argo etc. to GPS too.
An alternative is to use an external A/D converter clocked by the
freq. standard but many modern PCs doesn't have a serial "COM"
port and USB is a little bit too complicated for homebrewing.
(Well, www.ftdichip.com might do the trick...)

Thanks again for the great software!
