Interpretation

During 0130–0430 and 1130–1630, TWR and SMC use a combined frequency of 123.350 MHz (main), with 119.150 MHz (standby), while APP uses 122.950 MHz (main), with 119.150 MHz (standby). Outside these periods, TWR/SMC and APP are available on 123.350 MHz (main) and 119.150 MHz (standby). See EAIP India VOCL AD 2.18.
