i Don,
this type of receiver sometimes need a good 15-20 min to find their place...
hey are not very sensitive...
lso if the receiver comes-up in NMEA mode then they probably used a spec
pplication and   it
s much  better   to   config the 20 pin connectors to Rockwell-binary
ode and use the " LabMon 49 " software  until the receiver alive and then
ou can config back to NMEA mode.....
Rgds Ernie.

 test all my GPS receivers with a hockey puck type antenna attached to the
all 
 my hamshack, which is upstairs, but under the ceiling and the roof and I
ave 
ver had one fail to lock within reasonable time. With this setup,
hunderbolts 
casionally go on holdover, but never for very long.
f course, when I plug them in the external Symmetricom antenna, they
ypically 
e more satellites and don't go into holdover.
 am in Northwest Florida, so probably at a lower latitude than most of you,
o 
e same setup farther north may not work as well.

bsolutely yes, the antenna must see the sky, not the ceiling. Even very
nsitive GPS receivers must have a good view of the sky for the first fix,
en you can bring the antenna indoor. You can try positioning the antenna
ry near a window for just a test but better a good view. The car roof is
ay but you must wait several minutes (12 minutes at most) to let the
ceiver download the almanac.

 Maybe I didn't take positioning seriously.
 The antenna is currently on a shelf above my workbench, ....there is a
ceiling and an upstairs above it. Then the roof.
 Is it very critical to be outside in order to 'see' the sky?
 I did take it out once and set the antenna on my car roof, ....but still no
satellites.

 Step one...is the antenna in a location where it can see they sky?
 Sorry if it is a stupid question but you already said it was plugged in. :)
