I had a similar problem with a 5 MHz OCXO from their ULN series. There was a bad solder joint on the output connection, easy enough to fix once I got the unit open.
In my case I used a Dremel tool to cut the seam. Suggest wearing a dust mask, obviously, and keep your cuts close to the perimeter of the can, in case the PC board comes right up to the edge like mine did. -- john, KE5FX > -----Original Message----- > From: [email protected] [mailto:[email protected]]on > Behalf Of Ed Palmer > Sent: Monday, January 19, 2009 2:05 PM > To: [email protected] > Subject: [time-nuts] Wenzel Oscillator Repair > > > Hello, > > I have a piece of equipment with a Wenzel 5 MHz oscillator from the > Timekeeper <http://www.wenzel.com/pdffiles1/Oscillators/TMK.pdf> line. > It's functioning (that is, it's on frequency), but the output level is > 20 - 30 db lower than it should be.
