What is being checked

• i
  info: WAVA-FM - ARLINGTON, VA

  From the NRSC list: 105.10 MHz, PI code 56CA, FCC facility 4644.
• i
  info: RadioDNS lookup name

  10510.56ca.5a0.fm.radiodns.org (frequency 105.10 MHz, PI 56CA, country code 5a0)

1. RadioDNS registration

• ✓
  pass: Registered

  10510.56ca.5a0.fm.radiodns.org points to the station's authoritative domain: wava-fm.sim-cms.net

2. Service discovery (SRV records)

• i
  info: _radiospi._tcp.wava-fm.sim-cms.net: not published
• ✓
  pass: _radioepg._tcp.wava-fm.sim-cms.net published

  priority 0, weight 5, port 80 -> wava-fm.sim-cms.net
• !
  warn: Only the older _radioepg record is published

  What to do: Add _radiospi._tcp.wava-fm.sim-cms.net on port 443 as well, so receivers that use HTTPS can find the SI file.
• i
  info: _radiovis._tcp: not published

  Slideshow/visuals (STOMP) - optional, only needed for a live slideshow service.
• i
  info: _radiopush._tcp: not published

  Slideshow/visuals (Server-Sent Events) - optional, only needed for a live slideshow service.
• i
  info: _radiovis-http._tcp: not published

  Slideshow/visuals (HTTP) - optional, only needed for a live slideshow service.

3. Service Information file (SI.xml)

• ✓
  pass: HTTP endpoint http://wava-fm.sim-cms.net/radiodns/spi/3.1/SI.xml answered

  869 ms, 5,880 bytes
• !
  warn: The SI file is served through a redirect

  http://wava-fm.sim-cms.net/radiodns/spi/3.1/SI.xml -> https://wava-fm.sim-cms.net/radiodns/spi/3.1/SI.xml -> http://wava-fm.sim-cms.net/radiodns/spi/3.1/si.xml -> https://wava-fm.sim-cms.net/radiodns/spi/3.1/si.xml

  What to do: Some receivers do not follow redirects. Serve the file directly at this address if you can.
• ✓
  pass: Content type is text/xml

  Accepted. (RadioDNS's own guide shows application/xml.)
• !
  warn: SI file has no caching headers

  What to do: Add Cache-Control: max-age (for example 86400 for 24 hours). Without it, receivers guess - and some ignore the content.
• !
  warn: The file does not strictly follow the official SI schema (3.1)

  line 5: Element 'longName': This element is not expected. Expected is one of ( shortName, mediumName ).
  line 58: Element 'genre': This element is not expected. Expected is one of ( bearer, radiodns, geolocation, serviceGroupMember, ##other* ).

  What to do: Many receivers are forgiving, but strict ones may ignore a file that does not match the schema. RadioDNS's SI tool (si.radiodns.org) can rebuild a correct file.
