Abstract

Covers those performance requirements for Very High Frequency (VHF) Frequency Modulation (FM) sound broadcasting transmitters operating in the frequency band 66 MHz to 73 MHz, and modulated in accordance with ITU-R Recommendation 450-2 [1], which has some bearing on the Radio Frequency (RF) spectrum.
