Those countries have protested strongly at the use of 225 kilohertz for a national channel.
The audible range of sound is 20 hertz-20 kilohertz.
It operates at 930 kilohertz, with a daytime power of 5,000 watts non-directional, and 500 watts directional at night.
The unit "kilohertz" was not introduced until 1960.
The self-quenching frequency was ten kilohertz, just above the highest audio frequency the headphone could reproduce.
The rate is also variable, capable of ranging from kilohertz to gigahertz.
Each 200-line picture required 20 seconds for a complete video transmission and it used a radio bandwidth of about 1.2 kilohertz.
Absence of output transformer and global negative feedback extends full power frequency response into hundreds of kilohertz.
