Hi Jim
Will send direct shortly, if nothing arrives let me know and I'll try
again.

Hi Jim
The PC containing my archives is busy and I can't pull any files off right
now, sorry about that, but I've confirmed that the component level service
data I have is the same February 2007 version as can be found here..

I would, but I don't have the time at the moment :)

Many thanks for all the replies.
Nigel, thank you for the link. I did have this pdf, but was not reading it
correctly.
It has been suggested that perhaps the counter main board was set up
(modified) for a 12GHz channel 3. That would have required some mods to the
actual main board, but I am

Thanks for everyone's help here. I have done some further sleuthing.
I have a second 53132A which has a 3.0GHz Channel 3. So, I switched the new
channel 3 board into the old 53132A and it reads properly. Then, I switched
the old 3.0GHz Channel 3 board into the new 53132A and it also read
So they want to in-invent NTP?
I think NTP already services way more than 6.5 billion per day. The
problem with NTP is while it is nearly optimal and provides the best
time accuracy for a given hardware/network setup it is not technically
traceable even if the time really is from NIST

No, the suggestion makes perfect sense. A 12 GHz input board likely
has an internal prescaler with a division ratio that is 4 times that
of a 3 GHz input board, in order to have the main counter running at
the same internal frequency. For example, a 3 GHz input might divide
by 32 while a 12 GHz

I think I may need to clarify my prior posting.
Both old and new Channel 3 boards work fine (and read correctly) in my older
53132A counter.
Both old and new Channel 3 boards fail to work properly in (and read 4x actual)
the newer 53132A counter.

Hi Jim:
I've seen a similar problem when one end of a ribbon cable connector is
soldered to the wrong side of a PCB.
Maybe you can unsolder a connector and install it on the other side?
Have Fun,

Jim the 5 and 12.8GHz modules are the same part and the software/firmware set
the upper freq limit. I assume at least the 12.8 GHz option must be
unlocked/accessed most likely through the key pad. The 5GHz may be plug and
play.

Those who say the missing aircraft should be searched along the two corridors,
what measurement are they relying on? I think it is a one-way measurement of
time-stamped pings, which implies good synchronization of clocks between a
geosynchronous satellite and a moving aircraft. Antonio I8IOV
They only got one ping from INMARSAT at 64E above the Indian Ocean.
There was no other ping to triangulate the position.
One ping projects a circle on the Earth. The maximum flying range of the
plane determined the ends of the NE and SE arcs of that circle.
The news only gets stranger as time
My question was on what would be the expected accuracy of the circle's radius.

It depends on how accurately the bird can measure the round-trip time:
1 us = ca 500'
10 us = ca 1 mile
100us = ca 10 miles
1 ms = ca 100 miles
The arcs are loci of constant round trip time, projected on the globe.

Hi Antonio:
It's my understanding that the satellite sends a ping to each aircraft in it's low gain antenna pattern once every hour
by aircraft ID number.
The aircraft replies with a very short data packet that's time stamped (but without any location or other info other
than the ID).

A lot of these satellites have footprints for each antenna. I don't
know if the footprints are narrow enough to track a plane.
