If anyone out there is tempted to buy the GPS setup Larry is selling, I
have something else you might want to consider. The manual for the
reciever and xntp3 have the same ASCII string for time. In other words
it might cheap and somewhat easy to set up a stratum 1 network time
server with Linux (the cheapest part) on your home LAN. I don't know how
well that would work with SDR though. Maybe get two? :)

Some of the details are:
Driver type 20 Generic NMEA GPS Receiver (NMEA)
xntp3 (time server software included with most newer Linux CDs)
The ASCII string starts out "$GPRMC"
URL for xntp3 is http://www.cis.udel.edu/~ntp/

You can get a Linux CD with the newest unofficial version for about $7-8
US from places like CheapBytes, InfoMagic and Linux Mall. The time
server software is most likely on the CD. 

There's also a driver for the 1 PPS signal for atomic clocks and other
receivers. You might be able to write a driver (simpler than a kernel
driver) for one of those $100 WWVB receivers.

'just thought someone might be interested.

,Greg
