Randy,
a splitter for two GPS receivers is a bit different from a normal power
splitter in that both receivers should see 50 Ohms impedance @ RF but
abt. some hundred Ohms @ dc. That is because each receiver will try to
measure the (active) antenna's dc current to find out whether the
attached
Whatever route you go down, remember you need to get DC to the antenna from
one of the receivers, and block DC to the other.

I purchased on ebay four rubidium LPRO and I'm quite satisfied with them.
The lamp-Volt parameter (which is an indication of the lamp's health) was
respectively 8.4, 7.95, 6.8 and 5.1 Volt.
When an LPRO leaves the factory its lamp-V is around 12V. A drop of up to 3 V
would be expected in the

Are these switches the same as the ones in the 1996? Mine works perfectly now,
but if the switches are a ticking time bomb, I'm going to move it to a area
with better temperature control, and start looking for a donor unit just in
case.

In my original copy of the 1992 manual, there is only one jumper
indicated on the GPIB board. It is at the front of the board. Pages
7-34 and 7-35 show it. On the first page it says : Make certain the
jumper plug is installed in the upper two pins of SK4 as shown.

Hello All;
I checked my Tom-Tom One XL today, and #32 showed up on the satellite
screen, although it's signal strength bar was grayed out, even
though the signal strength was higher than most of the other satellites.
I'm guessing that this means the GPS was seeing #32 as unhealthy, or
