your right again Audioguru
I caculated withthe resistor values reversed.
the pulse position modulator you mentioned (need to look at data sheet) and varying the voltage on pin 5 sounds like a VCO using a 555 (have a circuit somewhere?
I thought about that, its still simmering in the gray matter
as far as a "siren" perhaps , depends on what one calls a siren.
but yes I want the sound to have 2 seperate speakers or ? and have them crisscross
#1 = 2khz, 3khz,4khz,5khz,6khz then back again 5,4,3,2,
#2 to start at 6khz and go down to 2khz then back again
Hoping that it will really bother the deer and scare them away for good.
