[VHFcontesting] Median RF Noise Floor

[John Santillo]

Hello VHF's,

 

I have been reading ITU-R P.372-10 and other Noise Power documents on
Terrestrial RF background noise.  I have been trying to determine what is
considered nominal background RF noise.  

 

If I interrupt the graphs and equations properly I come up with the
following RF noise levels for median city area man-made, galactic and
natural noise for a 500Hz bandwidth.  

 

50MHz   = -112dBm

144MHz = -127dBm

222MHz = -133dBm

432MHz = -136dBm

1296MHz = -154dBm

10GHz = -150dBm

 

My question to the list is, has anyone reviewed other white papers or done
their own measurements that would yield credence to these numbers?   

 

 

73,

 

John
