[nrv-hams] Audio signal generator to borrow?

[J.C. Hassall]

Tnx Cam,
As usual, you're The Man!  I didn't think about a phone app, nor Amazon for
a kit.  I thought about using the rig's sidetone but I want to drive a
speaker and show the wavelength on the 'scope, so opted for the Amazon
signal generator.  And while I was there ...  Gads!  Is there anything
Amazon doesn't carry?  Back in the day, when I used to shop in-store for
groceries, I'd go in for $10 and come out with $50.  Same holds for Amazon
:-{  No self-control.

So, tnx for your suggestions.  Now to wait for the UPS guy :-)

The democracy will cease to exist when you take away from those who are
willing to work and give to those who would not.
Thomas Jefferson

I sometimes feel bad for the smart people - being simple-minded and easily
entertained is totally the way to go! ;-)
