[time-nuts] worth salvaging ?

[Pete Lancashire]

not in any way a scientific test

three antennas could 'see' sats after about 2 minutes. One can tell in
that one of the display options is to show sat number and state.

one antenna after about 10-15 minutes the sats one at a time would go
into a track mode,
then after another 5 minutes would finally go into lock. I don't know
where from track to lock
when the almanac gets updated. I know it is in that the button cells
died years ago.

Somewhere I may have a box of unused antenna/downconvers

tomorrow I'll gut one of the bad antenna/downcoverters and take a few pictures

antenna/downverter with plastic cover removed
