Noise Bridge...Measuring Receiver Input Impedance.

[Skywave]

Well, no, I haven't, but I have heard of the technique - but only "heard of": I'm ignorant of the details of the 'why' and the 'how'. Can you add any substance to this matter, Lawrence? I've always promised myself that one day I would build myself a wide-band noise source for measuring the SNR of comms. radios, so this topic of yours - which seems related - is of particular interest to me.
