In some cases, it is not enough to provide a broadcast frequency to describe a radio station. One must also know the sub channel. I propose two new properties:

  • broadcastSignalModulation to specify things like AM vs FM
  • broadcastSubChannel to specify the subchannel

An example would be:

{
  "@context": "http://schema.org/",
  "@type": "BroadcastService",
  "broadcastFrequency": {
    "@type": "BroadcastFrequencySpecification",
    "broadcastFrequencyValue": "89.3",
    "broadcastSignalModulation": "FM",
    "broadcastSubChannel": "HD1"
  }
}

+1 is SubChannel a fairly global term or standard here ? or is there a better international term ?
