Why Radio Shaft? You can get similar modules from lots of retired electronics (VCRs, TVs, Stereos...), and likely better quality. I've got a bunch of them, but haven't looked for data sheets for any yet, haven't had a need yet, but will someday. Most work off 5v, the center pin is the output. If you have an osciloscope, IR LED and signal source, it's simple to find the frequency.
Yes, I never hooked one up, but had a few ideas, did some research.
