>   Only FM?

>   During the Kosovo war (fall of 1999), State Department officials 
>decided that young people of today listen only

>installation of five stations distributed

>   For example, the radio horizon is only 100 miles from the Romanian 
>5,000-foot mountaintop installation.
>   Belgrade is 80 miles away, but it only takes a 100-watt jammer to 
>lock on to every FM receiver in the coverage
>   area.

>   Although the IBB uses Harris 10 kW transmitters with eight stacked 
>Scala log-periodic arrays having 14.5 dB
>   total gain for an effective radiated power of 300 kW, President 
>Slobodan Milosevic¹s Serbian government can,

>   The State Department and IBB argue that we need new methods to

>   No substitute for high power

>   FM, the Internet or satellite transmissions cannot substitute for 
>a network total of 144 high-power, 250,000-
>   and 500,000-watt medium- and shortwave stations worldwide. And 
>even these facilities need to be upgraded
>   in order to adequately cover today¹s international hot spots.

>   The dollar value of all IBB technical facilities is in the order 
>of $3 billion to $4 billion. They could probably not
>   be duplicated today for that amount, and the engineering talent
