Is your station ready for hybrid radio?

What is being checked

• i
  info: KTCS-FM - FORT SMITH, AR

  From the NRSC list: 99.90 MHz, PI code 4272, FCC facility 5220.
• i
  info: RadioDNS lookup name

  09990.4272.4a0.fm.radiodns.org (frequency 99.90 MHz, PI 4272, country code 4a0)

1. RadioDNS registration

• ✓
  pass: Registered

  09990.4272.4a0.fm.radiodns.org points to the station's authoritative domain: ktcs.com

2. Service discovery (SRV records)

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

  priority 0, weight 0, port 80 -> www.ktcs.com [target is an alias of ktcs.com]
• !
  warn: SRV target www.ktcs.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 www.ktcs.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.ktcs.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://www.ktcs.com/radiodns/spi/3.1/SI.xml answered

  59 ms, 2,156 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 13: Element 'mediaDescription': This element is not expected.

  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.
