That would be nice, but I imagine that inside a computer is a pretty nasty
with computer generated RFI.

Even better would be an automatic sweep function that would do the sweep
(with special AGC) and then report 150 SMeter values back to the computer.
With the Jupiter it would be just a matter of using the sweep that displays
on the LCD, but providing those results to the computer. With the Pegasus,
they'd have to add some code from the Jupiter.
