Hi Henrik,

I will try your code tonight. I only have 12F683 PICs and to change to 12F1840 will take some time for me (I知 still using an older version of PBP) which, more than sure, does not support this chip.
If I can get modulated 1 MHz from one chip for now it will save me a lot of time with the testing and a lot of space on the board.
I will post my findings as soon as I have results.

As always thank you for your help.

Regards,

Nick
