[time-nuts] SSR-6t Connector

Tom,

Synergy already has a carrier board to put the SSR-6T receiver into a VP, UT,
UT+, etc. socket. All that is needed is firmware support for the old 8-channel
messages. I am planning to implement this capability for Synergy. It's just a
matter of time and priorities. Eventually Synergy will have the solution for
this problem. If you could gather a list of Time-Nuts people who would like one
or more of these and send it to Art that could speed the process along.

Hi Paul,

I'm pretty sure the hp Z3801A and 58503A/B (and perhaps other 1990's era) GPSDO
use the Motorola Oncore VP receiver. It was, and still is, a famous GPS timing
receiver. Later, many GPSDO evolved to use the Motorola/iLotus M12 receiver.

The new Synergy SST-6T is a clever combination h/w and s/w that turns a uBlox 6T
& PIC into a PCB that is both h/w and s/w compatible with an M12. It's a drop-in
replacement. But as such, it won't work in a device that is uses an old Motorola
UT/GT/VP receiver.

I suggested that they also come up with a board that is VP compatible, but you
realize the number of 15-year-old Oncore VP's in the field is probably not that
high. It would make an excellent labor-of-love project to create a VP-compatible
uBlox 6T board, but it's probably not something you can make a business case
for.
