[BC] Intentional Conducted vs. Radiated...

[Burt I. Weiner]

I believe that 15.207 would relate to a campus or 
other type of carrier current stations where the 
intentional radiator is a conducted signal rather 
than one radiated from an antenna.

In the past the Commission has used the limits 
set forth in 15.209 to determine if a device 
connected to an antenna as an intentional 
radiator such as the goodies we have been 
discussing meet compliance.  The measurements on 
these devices have been made in accordance with 
15.209 to determine whether or not 15.219 devices 
comply.  If such a device is constructed in 
accordance with 15.219 it should comply with 15.209.

When I was a kid my Electronic Baby Sitter did a 
nifty job of exceeding the limits just a tad.

Here is a good source of Part 15 stuffs:  http://www.part-15.org

Exactly!

A convenient interpretation.

Check 15.207
