Hello Wolf,
 
About the 10MHz oscillator you asked I can only give a hint, that QK in rombic means Quarzkeramik, the German company which locates in Stockdorf. The company belongs now to Vectron Group.
I have lot of QK-made high stable crystals in glass holders, but I am not familiar with the type you asked. Most probably it is OCXO.

Subject: LF: 10MHz OCXOs - one more query

Dear Group,

I am also looking for details for a 10 MHz OXCO(?!) which I bought at the HAM Radio fair in Friedrichshafen this year. The dealer did not have much info about it (i still await his email) so any info about this is very much appreciated. He only told me it was once used in "commercial equipment" whatever that means.
The oscillator is encapsuled in a metal housing, about 5 * 5 * 1.5 cm, and labelled:

"QK" (in a rhombic company logo)
"Quarzosz. 770810 - 10M"
"10 MHz 12V= +- 10%"
"BS 15659"

There are 8 pins on the bottom. I am not even sure if its really an OCXO or a TCXO, I didn't dare to connect the DC power to check if smoke or a rectangular wave comes out of the little cube...

Regards,
Wolf DL4YHF.
