Mostly 10 MHz and 5 MHz sources would be tested.

I would be interested in whatever you come up with. My logging is at the

A partial GPIB-network spans the backside of the workbench, but it needs

My preferred platform is however Linux and in particular Debian. Just to 
keep things a bit interesting.
