I'm interested in obtaining your defective high performance crystal oscillators. By defective, I mean 01. no oscillation 02. wrong frequency 03. parastic or spurious oscillations 04. low output 05. distorted output 06. frequency jumps 07. poor or no temperature control 08. unstable frequency 09. frequency drift 10. frequency trim out of range 11. intermittent 12. poor or excessive phase noise 13. rattles when shaken or any other problem not listed above. I plan to do a failure analysis and try to understand what caused the problem and how frequent it is. I plan to post the results for everyone to review. I'll be happy to pay shipping cost and some nominal fee. Please contact me offline and let me know the make and model, what's wrong with the device(s), and the estimated shipping cost. Least expensive method is preferred. This is a long-term project. I plan to build a history of failure modes across a broad range of products so we can understand the reliability issues better. Thanks, Mike Monett
