Slight misunderstanding here. I'm talking of the kind of tweaking and
peaking us radio hams have to do when tuning intermediate frequency
stages of amplifiers. The effect is much more easily seen with an
analogue meter.

yes I can understand how flicking needles can make things easiier for
some. But the majoroty I think are better off with a DMM, some of those
have anolgue displays if you really need it. Are they many radios hams
left, our rad-soc in the uni disapeared 20 years ago.

If you're dealing with a receiver so old as to have IF coils that need
tweeking, a low impedance AVO is probably the correct tool for the job as
voltage measurements will be given with that too.

With high impedance circuits a low impedance AVO can make a big difference
to the reading. Which is why a modern DVM is so much better. ;-)
