That makes life a lot simpler and makes the construction simpler too. And if you don't mind SMD there are new sub 1ppm VCTCXOs available for under $10. On the latter watch out because some of these oscillators use digital temperature correction and while they meet spec, the correction is quantized. Make sure the temperature correction is analog. -- Brian Lloyd, WB6RQN/J79BPL 706 Flightline Drive Spring Branch, TX 78070 [email protected] +1.916.877.5067 _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
