[time-nuts] Re: Oncore UT+ Synergy SSR-VP/UT replacement

[Gregory Beat]

   Tom -
   In August, I e-mailed Art Sepin at Synergy to discuss this offering and
   order a replacement GPS Board for my Symmetricom 58503B GPS Time and
   Frequency Reference Receiver. While the 58503B receiver can correct for
   the internal GPS receiver WNRO issue, I desired faster TTFF and better
   sensitivity.  “Time for an update”.
   My 58503B receiver already had a Motorola M12+ receiver with a Goshay
   adapter board.  Bill Goshay was an engineering manager at Datum/Efratom
   in Irvine, CA and founded his own company after its merger with
   Symmetricom.
   Art Sepin did say that an early order was for a HP/Symmetricom 58503B,
   and reported to work.
   I ordered Synergy P/N 16U54524G-R5 , SSR-UT+/S (Straight MCX) GNSS
   Receiver
   in August 2022.

   Due to the current part shortages and delays (u-Blox SSR-series
   receiver & EEPROM),
   I hope to receive this replacement Synergy board in 1Q 2023.

   There is a "plug and play" solution, but I have not tried on myself.
   With a u-Blox GNSS receiver upgrade you have a really nice system.
   As I remember the 260 quartz oscillator has very good phase noise
   (-105db at 1Hz).
   I would be interested if anyone has tried these. I know there were a
   few posts about the Jackson Labs M12 replacement in the Symmetricom XLI
   and I found those work well.
