Robust RF Links

[dhouston]

I have a signal strength meter, but it doesn't have a spectrum display. I have a feeling that the welders EMI is pretty broad spectrum.

How is this coming along?

I just came across the XRF which, while a bit costly, might work in your environment given that it's tunable over such a wide range (and probably has power output higher than legal for the US). The developer asked me for help doing an XRF to X-10 RF Gateway which only took a few minutes to explain. I can ask him if they've had any experience with TIG. Maybe they could even test it if there's someone nearby with TIG.

Thanks Dave. The project has been on hold for the last week. I got sidetracked (pleasantly) by a friend of mine at Freescale Semiconductor. I got their codewarrior development system in exchange for a commitment to do my next project using their hardware and software tools so I have been studying their IDE and brushing up on my C++ skills. I plan on getting back to it the welder project tomorrow. I will check the XRF out. I have a Miller Dynasty 300 TIG (inverter type) so I can do the testing myself. I'll keep you informed of my progress on this thread.

Thanks again for your help.
