Hi Rob,
Thanks for the feedback.
You are right and your comment about the task on your hand in an understatement.
However, us Aussies never give up. I do agree the little brick does run hot,

Hi Jason,
Thanks for the email address.
Peter Vince has just sent me a technical manual in PDF, I hope there is some
hidden data that I could use in my quest to repair both units.
Should I find anything, I would will share the data or findings. I have been
on these 2 failed units for over 6 mont
Hi Vince,
I have been aware of the leapsecond website for some time, so thanks.
The japanese site provides a bit of extra data, but with no translation,
it is a bit hard to understand.
Cheers.

Hi!
On friday my iLotus M12M Timing GPS receiver. The Synergy GPS development
pack suited my needs very well and it didn't take long to have it up and
running, just what I needed after a hard day of work.
I have been running the WinOncore12 software and have noticed that the

As Jason says, John Cuthbertson was helpful and sent me a PDF copy of
the Ops & Maintenance manual, although it doesn't have a circuit
diagram in it. As it is 764KB in size, I have emailed it directly to
Gerald rather than post it here - if anyone else would like a copy,
just ask.

Bruce,
I've owned a Trak Systems 8821 for over a year, and had a problem with
the antenna side. Yours may be different.
My unit is designed to work with a powered antenna, and it feeds 12V up
the coax to power it. Apparently this is the "standard" voltage for TNC
antenna connections - the sm

A nick in the jacket allowed UV to break down fiber optic.
One receiver had failed and the other kept going for a while longer until I
sused what was up.

FEI don't issue schematics for their products, and obviously charge for
