[time-nuts] Efratom-102100 Rb.

[Jacques]

Hello,
I've put some more detailed pics of the PCB on my site  
(http://nixie.ramdac.be)      board2.gif & board3.gif
Maybe someone has an idea what those cryptic markings mean on the 
jumper field... I suppose the C-field is not adjustable electrically 
(not on connector), but where could it be adjusted? There is a hole in 
the physics package with some adjustment (C?, R?). I think it is R118, 
the big blue multiturn pot. For the rest I only recognize the 10(?)MHz 
oscillator & multiplier (60 MHz) on the top of the image.
All remarks/suggestions welcome.

73's de Jacques.
