Hello Ulrich and hello Nigel (nice to meet you here as well!), 

I would like to help if possible, as I am owner of a FRK-HLN 
with 5 MHz output. I own as well a operation and maintenance manual for 
the FRK (H or L) , but I realized quite soon, that the content of my
oscillator with 5 MHz is quite different as described and shown 
in am. manual, talking of the different 10 MHz circuits and boards, 
not mentioning the 5 MHz issue. I tried to find out the differences, 
but I stopped.
Since then I am as well looking for the correct manual and circuits 
for the FRK-HLN-1A2B2A, EFRATOM Part No. 703-200-8 5 MHz. 
Nigel, of course I am interested to help and to exchange informations, 
I have anyway to answer your last letter. 
I wonder if somebody could help with the special issue of manual.
greetings to all,

Arnold, DK2WT
