[Vintage-Audio] Re Audio Test Signals

[Duane Fischer, W8DBF]

Greetings All, 	
	
I need an audio test tape of frequency increased by X cycles per increment. Such
as from 50 Hz in steps of 50 up to 300, by steps of 100 Hz up to 3000 and by
steps of 1000 Hz up to 18000. 	
	
I know these used to be readily available, many consumers used them to test, or
was it show off, their reel to reel decks, cassette decks and so forth. Maybe
there is even one out there on CD.	
	
Do any of you have one I can get a copy of? I will reimburse you for any costs. 
	
	
I especially need the frequency range of 250 Hz to 3500 Hz. 		
	
Thanks.
