Thanks for the heads up!
I have a CH1-76 passive maser and I'd be interested in this more modern one but after pulling a lot of teeth to get decent documentation on that one I'd hesitate to get the newer one.
Another problem is the Hydrogen supply. If it is empty it will be almost impossible to get it refilled.
That said I'd still be tempted if I had the $ to burn.
Cheers,
Corby
