[MCARC] Audio generator

[Michael Philbrick]

Don't want to take a chance with your iPad; do you have an old phone
sitting around? Maybe your an android guy, don't remember. But, if iphone,
there's a tone generator app available that I was using about 10 years ago
in the professional environment and it seems to still be available; at
least I just checked and still on my current iphone. It has a volume slider
which might help with your signal level; don't know.

App's name:  Tone generator      But I see there are a multitude of apps on
the iphone app store.
