Thank you for the responses. I have not reached out to him yet. Want to see if there are other issues and I can easily add an external 60 KHz source and modulator right now to verify the other functionality. There is no schematic nor source code its a 8 pin uproc chip and as such has almost no IO. I can easily see a very simple fix but needs a change to the code behavior. (The chip it self can not do the modulation function. Thats why its OOK). But if the carrier were left on there is a LED that blinks to the time code sequence and that can drive a 1 transistor or diode modulator. Regards Paul WB8TSL
