Will this work as a 7.83 hz (schumann resonance) generator to infuence ambient room frequency....or does this have totally unrelated applications?

First off I know nothing about the application that you are interested in using this for. That being said this unit doesn't have the ability to dial down to .83 hz only whole numbers. The output is DC square wave. Hope this helps.

how do you keep the control on frequency instead of keeping defaulting to duty cycle setting? It is very difficult to control frequency due to this.

This is not the pulse generator you are looking for. This is a fixed frequency, varible width PEM generator. I think what you are looking for is something like this:"Radio Control Servo ESC Consistency Digital Tester 1-4S for Speed Controller" or "Electronic Speed Controller Servo Tester ESC for RC Airplane Helicopters" Both on EBAA

how can I connect this device to speakers and what do I need to do so?

this is a frequency generator not a radio. even if you could all you would get is noise.

Will this work for a diy "chaterbox" which would push no more than 20-24v in a pulse format every 3-5 seconds. with 2 9v batteries as input?

As long as you do not have a load that draws more than 25ma

Great product for the price!

Worked as described, set to 128Hz and produced 127Hz with a 5V feed wire. Used on electronically controlled alternator, works perfect for setting voltage via duty cycle. 10/10 would buy again.

Works great for automotive PWM modules

Works great. If i had to complain about anything, it doesnt allow for inverting the signal so youre stuck with a PWM+ output signal but thats not a big deal. The duty cycle is just reversed meaning, a 10% minumum 90% maximum required signal would be 90% minimum, 10% max when requiring PWM-. I have used this to test automotive fuel pump controllers and fan controllers that use a variable input PWM signal to vary speed of the fan/pump. The frequency adjustment makes it easy to determine the appropriate frequency range for the modules. The pwm output is accurate, verified with an oscilloscope. Ive used it to test and control Infinity fan controllers, Ford fuel pump driver modules (fpdm) and Dodge fuel pump control modules (fpcm) without issue.
