Thanks to all the responses.
A suggested off line contact with one of the persons involved with the limits produced confirmation of much of what has been said. If I may take the liberty to paraphrase his response - it was determined to prevent radio interference at an agreed upon distance of 30 feet with an accepted *average* signal level for the average radio receiver. TVs on the other hand could be back to back in an apartment setting by as little as 6 feet. Additionally, the corresponding limits and method of testing for conducted interference also followed. Obviously, much more was involved than what my little summary explains, but the original motivation was what I was primarily interested. The great resource available here at EMC-PSTC proven once again. Thanks again. Regards, Doug McKean --------- This message is coming from the emc-pstc discussion list.
