Ole,
I took a look out of curiosity. The prices are a bit all over the place.
I have not experimented with this.
Not sure of any advantage over the Lucent Ref1 and Ref0s that have a good
oven oscillator and actually work at a consistent price.
Good luck if you move forward and let us know how it works out.
Regards
Paul
