In the example I have the module input pin incorrect.
I've tried the other pin and still no success.

Does it need a short delay before the first transmission?
No need for pull-up or down resistors on lines?
(Just throwing ideas,)

Hi Robert,
Thanks for the ideas.
I incorporated a start delay in one version of the code but it made no difference.
It's all at 3.3v. According to code samples on Ciseco forum it should work with direct connection but i did wonder about this myself.
Maybe I'll try them. Documentation is sparse and confusing.
I wrote a routine that cycled through all the baud rates available, one by one, per second, but the module just didn't transmit. I watched the module input pin signals on a scope and could see the pic output arriving every second, so the code worked.
I've just received an account email for Ciseco forum activation and have posted on their forum regarding the problem. They only offer support via the forum.

Did you try HSEROUT?
Thanks Dick,
Tried that but no luck.
Seems from info from the user forum that they are faulty.
I can see signal applied to module from pic but there's no output, the main module is clocking but the rf output part isn't responding.

Rob,
I will be following your story with great interest. I have a similar project underway. I've purchased two XRF transceivers for breadboard testing. Not fired up yet ... still waiting for 3.3 V regulators from Digikey. My ultimate plan is a long range, one-way link with an ARF on the sending end a SRF receiver ... very much like your project.
Yes, saw your thread on the Ciseco forum. It does sound like your parts are defective .. Will be interested in how it resolves. BTW, I was not able to join the forum ... verification not working.
Regards,
Dick
Dick,
Yes it was interesting to say the least on their forum.
They didn't seem to like it when I gave them test results. What exactly did they want as a post "It doesn't work" perhaps, with no details of tests carried out.
Can't believe he thought that scope results weren't useful.
Trouble is for me, my friend paid for all the parts for this project. So far he's up to $200 ish for everything for the two units. That's not far off a commercially available solution. If I return the modules for a refund, which I don't want to do I prefer a tested pair, then there's still the ancillary parts to account for.
If you need a simple design for a yagi aerial for greater range I have a doc with details of one.
Rob
