Does anyone have a good source for a manual for a Kinemetrics
60-TF? I found the manual for the 60-DC, but that's not terribly
helpful. I would like to get it going as a backup reference here.
And if anyone was looking for something to do with that old
Austron receiver --
Hi all,
About a month ago I sought advice from list members regarding a
dysfunctional fluke.l monitor for my Thunderbolt GPS receiver. Someone
suggested that I contact Bob at fluke.l to see what he would do. I took
that advice and thought some of you would be interested where I am now.
Plus,
I seem to remember someone on this list posting that the original processor
was no longer available so this required a board change to accommodate a
new processor. I think the new processor also requires 3.3vdc but if you
Google the chip's part number I'm sure you can find all the specs and this
I've heard this discussed a few times, and the idea of using diodes to
regulate this way makes me very queasy.
Why would a real 3.3V regulator not be used?
If the new chip requires 3.3 vdc and there aren't 3 diodes on the board to drop
the 5 vdc down,
Hi Steve:
The last couple of board versions have a 3-terminal voltage regulator on
board. See the photos at:

The replacement board looks like the one pictured on Brooke's web site.
Same processor as the older board. Hope to get it installed this evening
or tomorrow, I'll post the results.
Thanks all for the help.

I finally took the plunge and ordered a thunderbolt on eBay and it
showed up on my doorstep today.
Of course, I haven't saved those old emails about where to get things
such as GPS antennas and power supplies. If someone could please point
me to sources, I'd appreciate it.
Also,
Because a real regulator costs more than 3 diodes and when you already have a
5V regulator, the 3 diodes work fine.

Removing the processor board is a challenge because (at least on the old board)
the holes are a little too tight for the pins, so even if you remove all the
solder, the pins will remain stuck.
I found it easier to cut all the pins connecting the two boards and unsolder
them one at a time.

Hi
You obviously will need +12, -12 and +5 supplies at the proper current levels.
Any GPS antenna that will run on 5 volts will work for checkout. There are good
pictures on the web showing what power goes to which pins. Current levels are
10 ma on -12, ~ 300 ma on +5 and a bit under 1A at
