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
08950.a6b6.aa0.fm.radiodns.org (frequency 89.50 MHz, PI A6B6, country code aa0)

1. RadioDNS registration

pass: Registered
08950.a6b6.aa0.fm.radiodns.org points to the station's authoritative domain: radiodns.prss.org

2. Service discovery (SRV records)

info: _radiospi._tcp.radiodns.prss.org: not published
pass: _radioepg._tcp.radiodns.prss.org published
priority 10, weight 60, port 80 -> radiodns.prss.org [target is an alias of contentdepot.prss.org]
warn: SRV target radiodns.prss.org 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.prss.org 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.prss.org 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.prss.org/radiodns/spi/3.1/SI.xml answered
348 ms, 261,298 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.
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.
info: Logo checks limited
Only the first logos were fetched.
pass: 12 logos downloaded and checked

6. Transmitters and streams

pass: FM bearer fm:aa0.a6b6.08950

Not checked by this tool.
warn: Stream OK: https://playerservices.streamtheworld.com/api/livestream-redirect/WEOSFMAAC.AAC
audio/aacp, 48 kbps
The file says 256 kbps but the stream reports 48 kbps.
No offset set (optional): if the stream runs behind the broadcast, an offset in milliseconds lets receivers line the two up.
