Is your station ready for hybrid radio?

RadioDNS lets connected car radios and receivers show your logo, name and stream. This free checker follows the same steps a receiver does and tells you, in plain English, what works and what to fix.

What is being checked

info: RadioDNS lookup name
09950.9955.9a0.fm.radiodns.org (frequency 99.50 MHz, PI 9955, country code 9a0)

1. RadioDNS registration

pass: Registered
09950.9955.9a0.fm.radiodns.org points to the station's authoritative domain: kgu-fm.sim-cms.net

2. Service discovery (SRV records)

info: _radiospi._tcp.kgu-fm.sim-cms.net: not published
pass: _radioepg._tcp.kgu-fm.sim-cms.net published
priority 0, weight 5, port 80 -> kgu-fm.sim-cms.net
warn: Only the older _radioepg record is published
What to do: Add _radiospi._tcp.kgu-fm.sim-cms.net on port 443 as well, so receivers that use HTTPS can find the SI file.
info: _radiovis._tcp: not published
Slideshow/visuals (STOMP) - optional, only needed for a live slideshow service.
info: _radiopush._tcp: not published
Slideshow/visuals (Server-Sent Events) - optional, only needed for a live slideshow service.
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://kgu-fm.sim-cms.net/radiodns/spi/3.1/SI.xml answered
2126 ms, 5,869 bytes
warn: The SI file is served through a redirect
http://kgu-fm.sim-cms.net/radiodns/spi/3.1/SI.xml -> https://kgu-fm.sim-cms.net/radiodns/spi/3.1/SI.xml -> http://kgu-fm.sim-cms.net/radiodns/spi/3.1/si.xml -> https://kgu-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.
