With an outboard +/- 12 Volt power source my 2100F is now working fine.
A new replacement package is therefore desperately needed.

Dear All,

Diving into the hardware, I found the DC-DC +5 to +/-12 V Power Source
defective. There may be something more but that is serious enough.

Thank you for your kind attention and help.

Thats what I was thinking also on the reference and emailed back to the
group.
I believe over time that internal switch to select 1,5,10 mc can get a bit
touchy.
If a operating reference is connected and checked to be correct toggle the
switch a few times to clean its contacts. It gets lonely sitting in there by
itself for years. ;-)
Regards
Paul.

Hi Antonio,

Ok.  I just wanted to be sure that it was still up in Europe.  Canada
dropped their chains 3 months earlier than they said they would.  And
since Loran-C is no longer usable world wide, I figure Europe will be
dropping their chain soon.

The error indication you have described tells me that you have no
reference oscillator.  This could be for a couple of reasons:

1) you have no frequency standard connected to your 2100F
2) the switch, labeled 1-5-10, on the board stack visible when you hinge
 open the front panel is set incorrectly for your external frequency
 standard.
3) Your 2100F is broken.

Are you sure that your Loran chain is still up? In the US and
Canada, Loran has been decommissioned.
