Hello Ernie,

     Is this the RadioCode Clocks IFS8000R that you are interested in?  We have
one, and the manual.  There are (small!) circuit diagrams, but no software
information.  I believe versions were available with a serial port, but ours
doesn't have that.

     You MIGHT be able receive MSF if you make or buy a large loop aerial, but
there is always the problem of interference from PC monitors running at 1024x768
whose line frequency is very close to 60KHz.  I wonder if you might not be better
off receiving DCF, and then using a PIC to re-create the MSF code?  But you would
also have to re-create the 60KHz from the DCF 77.5KHz, so it might be more
trouble than it's worth.  Our IFS8000 no longer has an aerial - it was replaced
by a GPS system some years ago - but was left in the bay as a standby running in
"Freeze" mode.  It has proved very stable - it is currently running 7.5 x 10^-11
fast, but was 7.0 x 10^-11 a year ago, so ageing is very low.

     If we are talking about the same unit. I will try and scan the manual.  I
see that Gorgy Timing in France has a page on their website briefly describing
the older OCXO version, the IFS800: http://www.gorgy-timing.fr/ang/rtf/ifs800.htm
 and they have a branch in Karlsruhe - I wonder if they would be able to provide
you with more economical help?

           Happy New Year,

                 Peter Vince  (London, England)
