Thank you for the reply.
I'm actually trying to break this down to the signal timing, the lead in signal, device address, command , and lead out, using time in mS of on and off.

So I've used the pronto IR tool, and the IR Code Doctor to check the code with your suggestion (replacing set 3 with 0022) and it definitely works.

I'm using the information here:
[Link: hifi-remote.com]
to try and determine the timing, and they mention that:
"Doing the arithmetic we see that this code uses a base time of 550 microseconds"
Do you know how I determine this for this code? So I can come up with the mS values?
Thanks,

PS. Thanks, I think I got it. 1 / (the carrier freq) / 22. I think. I'll give this a try.
