Is your station ready for hybrid radio?

What is being checked

• i
  info: RadioDNS lookup name

  10670.1a3d.1a0.fm.radiodns.org (frequency 106.70 MHz, PI 1A3D, country code 1a0)

1. RadioDNS registration

• ✓
  pass: Registered

  10670.1a3d.1a0.fm.radiodns.org points to the station's authoritative domain: rdns.iheart.com

2. Service discovery (SRV records)

• i
  info: _radiospi._tcp.rdns.iheart.com: not published
• ✓
  pass: _radioepg._tcp.rdns.iheart.com published

  priority 10, weight 50, port 80 -> epg.iheart.com
• !
  warn: Only the older _radioepg record is published

  What to do: Add _radiospi._tcp.rdns.iheart.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.
• 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://epg.iheart.com/radiodns/spi/3.1/SI.xml answered

  32 ms, 1,408,477 bytes
• ✓
  pass: Content type is 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 1: Element 'link', attribute 'role': The attribute 'role' is not allowed.
  line 1: Element 'link', attribute 'role': The attribute 'role' is not allowed.
  line 1: Element 'link', attribute 'role': The attribute 'role' is not allowed.

  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.
