I thought that was a really neat idea. I just happen to have an HP 346B noise head and no meter. I must try it out when I get some time.

This is all very well but it still needs a receiver. How about using something like the Funcube Dongle and use the bias output as a switch for the noise source? This could then be used to optimise pre-amps for all bands up to 23cms. It needs software and very little hardware.
