Look at the output of the receiver on a 'scope (or soundcard as I've suggested before) and merely duplicate the waveform with your transmitter. That brand is one I haven't seen but most use a very simple protocol.

I can see the output on the scope but i donīt understand how to translate it o PBP code and send it via the parallax transmitter.

I have no idea about the Parallax transmitter (maybe you should be asking on a Parallax forum) but you need to measure the durations of the pulses and spaces and just duplicate them on output. With a PIC and the less expensive transmitters I prefer, I just use PulsOut, as demonstrated in my example in the Code Examples forum.

The parallax RF modules i based on the LINX chipīs
Yes i can se the output on a scope but how do i translate it to a PBP code?

I believe you will have to modulate it in some fashion, easiest and noisiest way is AM, FM is better, less noise, and finally you could pulse the output, likely the least reliable.

Hi Fredrick,
The code is hopefully not to critical....
The way I would start is to measure the smallest pulse and use this as the clock.
Set up one of the timers to interupt at this interval. Then just clock through 8 bit (byte) numbers that match the waveform.
ie. $8A = 10001010
