Hi Said,

Magnus might be busy until after the weekend.

After fixing my Rb - Thanks!!! - and collecting a few antennas, Magnus
headed for the wilderness with a car full of beer and music festival


Is anyone running a FE-5608A 19"-rubidium? The main internal parts are a
5MHz FE-2204A VCXO, and the FE-5607E rubidium package.
