It looks like this station has a LOT more to worry about than merely not having an RFR exposure sign posted... After reading the Notice of Apparent Liability and Forfeiture, it appears that nobody at the station had ANY knowledge of how the station was operating, and that there were a number of problems in addition to the RFR signage issue.
Add to that, that this station was fined for these SAME violations in 2002. Its knuckleheads like this that make things difficult for the everyone when they don't comply with the law. But it looks like the FCC was looking to take enforcement action, given the past history of the station management. You do have a valid question, though. And I'm curious whether at a given site, I individually, or all of the operators collectively, are liable for placement of such signage... In either event, I'm assuming that once the signage is posted - conspicuously - the requirement is satisfied. Maybe I'll play it safe and buy a sign or two for the building where my 900 machine is operating, and post it/them myself. But now the question that begs asking is: WHERE does this signage go? On the door which accesses the roof; or at the bottom of the roof stairway that goes to the roof level above the elevator penthouse (where the radio equipment room is); or on the door to the radio equipment room, or......... Unfortunately, as an amateur I don't own the high-cost surveying equipment necessary for making accurate measurements of all the RF on the roof (Police Dept, Fire Dept, other ham equipment, cellular, etc)... I only know the level at which my equipment operates. Mark - N9WYS -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Tony L.

At what power output level would either a VHF or UHF amateur radio repeater need to be operating before its owner should consider mounting a "RF Warning" sign on the equipment room door (assuming there's no other tx equipment in the room)? 240 watts on the FM broadcast band got this licensee a Notice of Apparent Liability from the FCC. What if my ham repeater is running 1/4 KW? http://www.fcc.gov/eb/FieldNotices/2003/DOC-279189A1.html
