The problem with them as a general HF receiver is the input is too sensitive, so that when presented with .001 t0 32 MHz it overloads and you get noise floor dominated by intermods. Put a bandpass in front. And all should be good.

You are right; it is amazing to see how far off some broadcast carriers really are.

It has the option 003. Quite the light show when it powers up. I have its external reference daisy chained with a radio and two other instruments sucking 10 MHz from my Thunderbolt. I have not decided what to do with the AT&T front panel input. Should I get a BNC adapter for it?
