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. /tvb ----- Original Message ----- From: "paul swed" <[email protected]> To: "Discussion of precise time and frequency measurement" <[email protected]> Sent: Thursday, December 20, 2012 7:41 AM Subject: Re: [time-nuts] SSR-6t Connector > Not to hijack the thread.
