[time-nuts] how to open a Trimble mushroom ?

[Robert Atkinson]

Hi Pete,
That is the same case as the Palisade. I've opened one before. It looks like it should unclip but does not. The two halves do clip together, but there is a "gutter" inside the circumference of the lower half that a molded edge of the top fits into. They fill the gutter with epoxy before clipping them together. I had to cut through the top to open it. It had a curved crossed dipole antenna and a GPS RX on a PCB. All highly inegrated. Have you tried powering it up using the Palisade / accutime connection info and montitoring the data pins?

Happy Holidays,
Robert G8RPI.

More goodies from storage

I have a few 'special' Trimble mushroom GPS's. I'm trying to open one up
but can't seem to get very far. I've pulled all the tabs out but still can't pry
the case open.

They interface between the two sections doesn't look welded or glued.

Here a couple picts

The data on these guys was trashed long ago when the company closed
up. I could not locate it anywhere.
