The transmitter alignment instructions for my Icom 751A tranceiver
calls for a 2 tone input during the alignment process....

"Insert 2 audio signals into the MIC Connector
1.9kHz at 3mV
1.3kHz at 3mV

Are there AF generators out ther that will generate more than one
tone?

They do exist - I'm in the process of doing some restoration on an old
Singer tone generator which does arbitrary pairs of frequencies.

These days, the easiest way to create a tone combination is usually to
use PC software. Generate two sinewave tones at the two frequencies
you want, with 50% amplitude or less, then mix 'em with the
appropriate relative amplitudes. There's lotsa free software which
will do this - e.g. Audacity on Linux and no doubt many others.

You can then play the mixed file out through your PC sound card, or
burn it to a CD-R and use a portable CD player to reproduce the
sound... whichever is most convenient. In either case, feed the
line-level output signal to a fixed or variable attenuator to get the
voltage level you need.
