Alternativefrequencies




TheRDSencoderallowsmethod"A"or"B"fortransmittingalternativefrequencies.
Thechoicebetweenthetwomethodsdependsonthestructureofthenetworkandthenumberofalternative
frequencies.
Thereisnoflagthatindicatestothereceiverifthealternativefrequenciesaretransmittedbymethod"A"or"B";the
differencebetweenthetwomethodsisjustonhowthelistsarecompiled.

Note:
ItisnotpossibletocompiledifferentlistsusingtheAandBsimultaneously.

“A”methodshouldbeusedonlywhenthenetworkhasamaximumof25frequenciesanddoesnotdifferentiate
regionalprogramming.

“B”methodisusedwhenthealternativefrequenciesaremorethan25orwhen,withinthesamenetwork,thereis
aprogramdifferentiation,suchaslocalnewsoradvertising,onlyoncertainfrequencies.

Thelistsmustbecompiledstartingfromthefirstandshouldbefilledleavingnoemptylistsinbetween:listsafter
anyemptylistwillnotbetransmitted.
