Re: [time-nuts] European Electronics Systems Radio Clock Model 100

Thank you for the information.  I have two Model 100 units, one has a
stick on label saying "GPS modified" the other has no label but as they
came from the same source at the same time, it may be that the label has
come off.  I am going to take a look inside the units later today.

The units have Maldon, Essex on the serial number plates.

I guess somebody in the timing community must have worked there.

Regards

Steve

  Hi Steve,
 
The name EES, or European Electronics Services Ltd, has been used more
than once, latest registration appears to be only about a year ago, and
might well have been used at one time by Siemens, but I think the
company you're looking for is, or was, EES Technology Ltd.
 
This eventually became Time and Frequency Solutions in Witham who were
taken over a year or so ago by Brandywine Communications in the US. I'm
still pretty sure that Radiocode clocks were also part of the earlier
mix but can't confirm that right now.
 
If checking Companies House records take a look at the filing history of
Time and Frequency Solutions here, especially early name changes.
 
https://beta.companieshouse.gov.uk/company/02627556
 
I've never used my model 100s, not quite sure why just never got round
to it, but they seem to have started out as straight MSF receivers, some
of which at least were sold to the MOD as transportable units in wooden
carrying cases with mains PSU and battery back up, and the update of
these to GPS seems to have been carried out some time later.
The mod included the addition of a separately packaged diecast box with
a GPS antenna on top, and containing a Motorola Oncore GPS module on an
interface board. I've just checked an antenna unit and it turns out the
Oncore module is a UT+, which is a bit more recent than expected:-)
 
I don't know if the GPS interface provides a stand alone 60KHz signal to
the EES 100 or whether that was also modified, although I suspect the
latter, and don't know either if the "updated" ES100s could also still
operate as an off air MSF, which may be one reason why I've not used
them.
 
Are yours the GPS version or originals?

The link to Siemens came from Companies House searches on the name. 
They reference the link to Siemens and mention Christchurch as a base
(however that could just have been a registered office for accounting
purposes and not the engineering / production location).

I have several model 100 units and was just about to put one in a timing
rack at the museum.

Does anyone have a service manual or any information on the 
Europeanlectronics Systems (EES) Radio Clock Model 100.
The company was part of Siemens but closed down in 2005.
The Model 100 was supplied by Plessey Defence Systems to the UK
military. 
Some models could be GPS disciplined 
Any information would be gratefully received for the Radio Communication

Museum of Great Britain.
(thanks to Robert with the hint about plain text !!)

Now there's interesting!

With EES being quite a small outfit based in Maldon, Essex, or so I 
thought, I'm surprised to hear they were ever part of Siemens, are you
sure about 
that?

For some reason I thought they eventually became part of Radiocode
Clocks, 
although I could well be wrong on that also, something not entirely 
unheard of :-), but do seem to recall several mergers etc amongst the
various UK 
off air standards outfits.

I've got a few EES MSF and Droitwich clocks, including the earlier
SFR060A 
and SFR200B, plus a 201 at the top of one of my racks in constant use,
but 
despite having some EES documentation I never did find much on the model

100.

With half a dozen or so of the GPS conditioned versions of the model 100

sitting in my garage I would also welcome some documentation. My notes
made 
several years ago seem to have disappeared but I do remember being 
convinced that the GPS option was very much an aftermarket afterthought,
for that 
read bodge:-), based on a retrofit Motorola Oncore if I remember
correctly, 
and not really something to get very excited about.
