Hi
The antenna is a pretty standard ceramic patch. No better (or worse) than any
other patch. No idea how quiet the preamp is or even if there is one. The uBlox
receiver is very good for sensitivity.

The time on the front panel of the instrument, at power on, shows Jan 1,

As you say, the gps health menu choice functions sometimes like you state,
other times I get error 41. I do also get the firmware and satellite
information.
Neither the Tracking or Lock led's illuminate.

For optimum results with respect to high RF frequencies, I'd expect
that you would need this cap to be annular, so that the cable can
pass through the middle, and the outside connects to the chassis
hole all around.

Bob,
Once in a while a mea culpa is required and we're posting it here so everyone
understands our commitment to the users of Synergy's products.
The Original Synergy Adaptor Board was designed to allow Motorola's newer 3
volt 12 channel M12+ to plug into an older 5 volt 8 channel UT+ slot.
And while this subject is still up, I want to let the group know that Synergy
*really* went out of their way to help me with this. I was a bit surprised at
their level of commitment to some ham radio operator who had bought a single
unit from them and probably didn't know what the heck he was

Wow there is a tidbit I did not know Ulrich owns Synergy. I knew he was
part of Rohde Schwartz and I firmly believe that I actually spoke with
him on 2 meters when I lived in CT on the way to work one day. A 2 meter
opening.
OK the total beg right now. Schematics for the FLL board (Not a typo)

If the device (gps) reports the firmware and satellites correctly (to the
ts 2100), I would assume so.
No other reasonable explanation exists.
Turns out that the original receiver was a svee6. Found the manual for the
gps and am comparing the default messages with the ace III.

Hi All,
Can anyone advise the supply voltage and range of the control voltage
for these gadgets?
Cheers,
