Hi Rich, thank you for your kind answer!
It will be really exiting to see whether I am able to copy the signal in June this year with this machine. I have started a discussion on this design as well (and got a lot of support) on the main Philips EE forum that is still very active these days on new Philips EE developments and designs: Philips/Schuco Elektronik. The specific Grimeton/SAQ link can be found here: VLF, Grimeton/SAQ und Mainflingen DCF77, there it is now even being discussed whether an original Philips EE design from EE1005/2005 (7.02, TV-Set Detector / Peilgerät für Fernsehempfänger) could be directly suitable (with one LW-Coil) or even optimized (multiple coils etc.) for Grimeton/SAQ as well!
Regards,
Jurjen
