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: K281BL - COYOTE, CA
From the NRSC list: 104.10 MHz, PI code D4FE, FCC facility 87357.
info: RadioDNS lookup name
10410.d4fe.da0.fm.radiodns.org (frequency 104.10 MHz, PI D4FE, country code da0)

1. RadioDNS registration

pass: Registered
10410.d4fe.da0.fm.radiodns.org points to the station's authoritative domain: radiodns.emfeng.com

2. Service discovery (SRV records)

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.
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://radiodns.emfeng.com/radiodns/spi/3.1/SI.xml answered
6 ms, 157,744 bytes
warn: Unexpected content type: none
What to do: Serve .xml files as application/xml (or text/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.
pass: The file follows the official SI schema (current (3.4/3.5))
Validated against the schema published by WorldDAB/RadioDNS.

5. Logos

pass: All five standard logo sizes are listed
warn: Logos have 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: 6 logos downloaded and checked
