Here it is:

< http://www.hoffmann-hochfrequenz.de/downloads/ocxo_carrierV2_pack.zip    >

These are the Gerber files as used by PCBway to produce my boards.

2 buglets:

- the 2 mounting screws for the 10811 should be slightly bigger.

   Drill as needed

- Unless the oscillator delivers only a small signal, the 2 emitter 
capacitors should

   each get 22 Ohms in series to adjust gain.

This will be addressed in V3. Circuits are included, comments and small 
change

requests are welcome, could be done shortly thanks COV19.


cheers, Gerhard
