And according to Dan's corollary, as soon as I walk into your office
with an RF spectrum analyzer to find and kill the culprit, your tablet
would start working perfectly. :-)
(In other words, it IS possible to measure and "see" RF interference
sources and coordinate frequency use, but in an environment where
multiple products are all using the same spectrum, anything goes...)
What's weird here in your example (but not unheard of) is the Wacom
isn't wireless, right? It's wired? Sounds like some SERIOUS heavy-duty
RF fields from that radio station are getting rectified in the wires and
some engineer saved $0.30 not putting RF bypass capacitors on the PC's
(That's an assumption... if it's USB... whoo boy do you have a lot of RF
