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.

If their AGC was better they would also make reasonable high
sensitivity receivers.
You are right; it is amazing to see how far off some broadcast carriers
really are.

Hi Chuck
I have number of these Make great precision receivers
Use it on the Thunderbolt, and turn on the 0.1 Hz counter to see if WWF
is
on freq. HI
More interesting game is to look at foreign broadcast carriers to see
who
are running professional plants locked to a standard, and who are the
cheap
outfits that somewhere the right freq.

Got one of these massive (by today's standards) beasts the other day.
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? Or replace it with a BNC
connector?
