Quite impressive that a hobbyist got his hands on two working active hydrogen masers. These are still by far the best commercially available frequency standards

Quite impressive that a hobbyist got his hands on two working active hydrogen masers. These are still by far the best commercially available frequency standards and cost a few hundred thousand dollar each.
- tvb 4y agoThat's the price -- when new. But most "time nuts" buy their atomic clocks well used on eBay or local surplus sales at a massive discount. For example the most recent H-maser on the hobbyist market went for just a few thousand. Granted it was in need of repair, but that journey is part of the fun of an atomic timekeeping at home hobby.
