[nrv-hams] Audio signal generator

[Cam Coble]

Sorry I didn't see this in time to get you something!
Something I've done in a pinch is use your phone or ipad audio.
Just search youtube for whatever audio frequency you want, and play that.
Here's a 700Hz tone:

Use an aux cord to break out the signal from the phone (or ipad).
The sleeve is negative, the tip and ring are right and left channel.

Hope that helps!
