UnderWater Antenna 125KHz Driver using a 16F628 @20MHz Example Code

This might make things easier:-)

Hi Jay.

I am not sure what RB3, RB4 and RB7 are used for. I guess the RB3 is the PWM signal output, but the rest?

As I understand it, you just want a 50% square signal at 125KHz?

Ioannis,

I have the beast generating 125KHz from the hardware module quite nicely.
To modulate a data stream, I am simply changing TRISB.3 from an Output to an Input.

Peace,

So, you are generating the 125KHz 50% duty cycle signal?
