With the availability of Motorola Oncore products and the Synergy pin
compatible it would make sense that some one does a board design that allows
plug in and saw tooth correction. We use a 14 pin PIC and a DS 1023 with
good results. Should also add a survey command. With the increasing cost of
Tbolts this is a nice alternative. The latest Shera makes it a nice GPSDO for
OCXO's and Rb's. The list price for a DS 1023 is just at $ 19 (lot of
silicon) but if some one does a group buy if the interest is there a $ 25 kit
price would be attainable. Right now I found a source $ 10 plus shipping I
paid just over $ 6, three month ago. using one of these in a Rb application
because of the long filter time may not even need saw tooth

Hi
The real question is what exactly can you get for how many dollars?
Old GPS cards aren't as good as the newer ones. There is a series of parts
out there that are derivatives of the original Oncore's, Res-T's, and
uBlox. The newer ones generally are more sensitive, track more sat's , and
deliver better timing. In all cases you want the timing versions of the
receivers.
I believe the current "best deal" is the Oncore clone you get by calling
up Synergy
http://www.synergy-gps.com
And mentioning Time Nuts. That's *assuming* they are still running the
$39(?) deal.
