[nrv-hams] Audio signal generator to borrow?

[Cam Coble]

Hey Jim,
Do you need something to produce the sound, or just the signal levels?
(Speaker or no speaker)
I have a few tools I could lend you, but you may already have something
that could work...

- Phone app: look for frequency generators
- Morse key tone generator
- Parts testers (sometimes they have frequency generators) like this one

- Or, I have one of these if you would like to borrow it, although in kit
form may be a fun project for you two!

73!
