I had a 5 MHz Sulzer in my lab for 20+ years, later adding a 2.5 MHz version. Living in Denver made tracking WWVB very easy with three different comparators over the years. I never managed to run them without a power interruption for anything close to 4 years. I also obtained two with an odd-ball frequency, but unfortunately have forgotten what an engineer at WWV told me about the purpose. After obtaining an Efratom M-100 I sold all four units to another frequency buff. If they suffered a power outage it took weeks for them to really settle down to their low drift rate.
