[time-nuts] Defective High Performance Crystal Oscillators

2014-01-06 Thread Mike M
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 0
