First of all, many thanks to those who gave help, hints, ideas, and schematics
(!) over the past eight months; all was appreciated!

including a Z3801A in a snazzy pull-out configuration with a dist. amp. All

What do you have handy? How nutty are you?
If you have 50 ft of something, give it a try.
I'm assuming you can try it easily, for example by tossing the ca
Thank you all for your replies. The sidecar is a bigger project than
I had in mind, but would certainly be a better and more versatile
solution.

I got my hands on a defunct Trimble Navigation unit PN 27760-10. I don't
know much about the unit other than it used to work very well in the late
90s until someone decided to do a firmware upgrade on it. The newest
firmware version is not compatible and now it's having some issues.

There appears to be three software-monitoring programs available, GPSCon

of these three programs or if there are any other available.

Hi Jeff,
I have used both SatStat and GPSCon on a Z3801A, Fury, and FireFly.
Satstat has no graphical interface, and it was so old that it was really
tough to get up and running on XP. But I was eventually able to get it up,

Hi!
Earlier this month the launched the latest of the GPS IIR-M sats, and today I
had the oppertunity to observe it. It seems it was brought quickly on air as
operational. It runs at PRN 07.
Cheers,

And they turned off PRN 10 the next day after making PRN 07 valid. It's
like they're playing GPS wack-a-mole.

Hi Jeff-
I have only used SatStat with my Z3801A, and it did take a while to get it set
up right under XP. I much prefer Tboltmon for the Thunderbolt. Now that both
are functional, I can start playing with them.
I found that the Z3801A with the std HP antenna and recommended cable didn't

Hello, All--
Can anyone tell me why, when I click on the Tboltmon
icon associated with my Trimble Thunderbolt,
that a little Serial Port Selecton window pops up
and why does my T-bolt only run after selecting
COM-4? Why can't this be selected once and then
forgotten about? It seems like an un-ne
I wish I knew how to bypass that too, so if you find out, please post the
answer back here.
On the other hand, if you have not already noticed, if the Tbolt is up and
running and plugged in the serial port when the computer boots, your mouse
will appear possessed.
It is a Windows "feature" where

Mike,
I don't believe the software has any option for saving a serial port
selection. At least I have never found one. It defaults to COM1. I
use a USB/RS-232 converter and COM 2 because COM 1 on my laptop is in
use by another application. I have to select COM2 every time I start
the program.

I'm thinking about using the TAPR TADD-1 six channel RF distribution
amplifier to distribute the 10MHz output of my Trimble Thunderbolt to a
few pieces of test equipment.
What does the TADD-1 do to the phase noise characteristics of its
outputs as compared to the phase noise characteristics of
Marty,
Thanks for the link, I did not know about this new software. I will try it.
The manual appears well done too.

Matt,
Not seeing a better alternative posted for the Racal 1992, and having dozens
of similar bad Toko switches on some Pacific Measurements 1038-N10 Scalar
Analyzers, I decided to buy a bunch of the Jameco ones and give it a try.
Definitely not a form fit replacement. But if you're not too asthe
I fixed the switches on my Pacific Measurements 1038-N10 by adding a small
coil spring to the insides of each switch. I don't remember it being very hard
to do. There is even a place in the center of each switch that is perfect for
putting the spring. The springs were something I had around in b
