[time-nuts] Symmetricom® TS2100-GPS update and conversion

[Gregory Beat]

The TymServe TS2100 arrived this afternoon.  So I started with the GPS receiver swap (update).

I removed the Trimble ACE III receiver (39818-C), but noted that this specific unit had a "widget board" (65398.69) on the SMA antenna connector and 2 wires (DC power) to the 3-pin header on the main board.

Was this board used to support +12 VDC powered outdoor antennas?

Installed the Heol N024-TS-V2.1 receiver (ACE III clone w/corrections) and 
connected a Trimble 28367-00 GPS antenna (small mag mount) to the receiver's antenna port. 

From a dead cold start, in urban canyons, I had tracking in about a minute and lock in about 20 minutes.  So far, so good.  Next will be the TCXO to OCXO conversion (MTI 240-0530-D).
