complained. But invariably when the disucssion does come up, so does
the mention by someone that by using the scope, it was
easier/faster/better.
have also seen people who knew there was more performance and then
used a scope to tweek it. Could be just that some people have bad ears ?
The software scopes are limited to 20khz or some such, but they are
free. a resistor is a quarter at radio shack.
It adds a tool to the box and might be more of a PITA than it is useful.
