Is your station ready for hybrid radio?

What is being checked

• i
  info: WVRB - WILMORE, KY

  From the NRSC list: 95.30 MHz, PI code 8DD7, FCC facility 69991.
• i
  info: RadioDNS lookup name

  09530.8dd7.8a0.fm.radiodns.org (frequency 95.30 MHz, PI 8DD7, country code 8a0)

1. RadioDNS registration

• ✓
  pass: Registered

  09530.8dd7.8a0.fm.radiodns.org points to the station's authoritative domain: radiodns.emfeng.com

2. Service discovery (SRV records)

• i
  info: _radiospi._tcp.radiodns.emfeng.com: not published
• ✓
  pass: _radioepg._tcp.radiodns.emfeng.com published

  priority 0, weight 5, port 80 -> radiodns.emfeng.com [target is an alias of dlywqc0l0i27.cloudfront.net]
• !
  warn: SRV target radiodns.emfeng.com is a CNAME alias

  DNS rules (RFC 2782) say an SRV record should point at a name that has address records directly, not at an alias. Many resolvers cope, some do not.

  What to do: Give radiodns.emfeng.com its own A/AAAA record (or point the SRV record at the real host name).
• !
  warn: Only the older _radioepg record is published

  What to do: Add _radiospi._tcp.radiodns.emfeng.com 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.

• !
  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.
• ✓
  pass: The file follows the official SI schema (current (3.4/3.5))

  Validated against the schema published by WorldDAB/RadioDNS.
