Are there AF generators out ther that will generate more than one
tone? The units I am seeing seem to generate just one tone (or at
least the used stuff out ther that I could afford)


Yep. To add to the other reponses, there are two-tone audio
generators used for two-tone control testing of commercial gear.
I've got one from my dad's estate that does two-tone-sequential
with adjustable duration for each tone, and two-tone-combined, and
single-tone. Thumbwheel freq(s) select from 100 cps to 9.999 kcs.
Pot adjustable tone durations (and delays), and levels.
It's probably 15-20 years old: Automated Industrial Electroncis
Corp., Model 2TSG-1.

They must show up on eBay from time-to-time. Google claims several
'hits' there -- but a search on eBay at this time shows none.
