Hi,
Anybody knows the design of JFET Crystal oscillator for 10MHz. I designed the oscillator it is running fine in simulation but when I am putting it on board its going weird-----No output.Please suggest me the changes to be made in order to make it oscillate.Please find oscillator cct attached
 

This way it won't work

see the sample attached it is not my design and owned by EI9GQ EMON SKELTON
thanks to him -- TRY IT IT SHOULD WORK
istead of varicap connected to stabiliser circuit you may connect it to a variable voltage derived from a 5V reference.
 

This works well at 10MHz. Output will be on the source of Q1. R2 value can trim the frequency
