Common wave train radio: Optimizing reliability and expenditure by use of a new adjustment process
A new process to adjust common wave train radio chains is proposed. It allows an effective alignment of phase shift of modulation signals and of frequency deviation so that the time for adjustment can be reduced significantly. Furthermore, the train radio line can operate during maintenance without considerable interruption by use of a new type of test signal, of GPS for time synchronisation and of a remote-controlled generator.
