Narrow-band FM system for television links: Interference between FM and AM television signals

The Band V FM television links used for television outside broadcasts have suffered more and more from interference as the network of UHF television broadcasting transmitters has expanded. There is also thought to be an increasing danger that Band V Links will cause interference to broadcast television reception. Experimental work was carried out to determine whether reducing the bandwidth of the links can reduce the problem of mutual interference between the links and the broadcasting services in adjacent channels in Band V. The conclusions drawn are that the adoption of a narrow-band VSB system could reduce adjacent-channel interference.
