What is being checked

info: RadioDNS lookup name
09050.6cf3.6a0.fm.radiodns.org (frequency 90.50 MHz, PI 6CF3, country code 6a0)

1. RadioDNS registration

pass: Registered
09050.6cf3.6a0.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
653 ms, 261,556 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.
warn: 12 logos downloaded and checked
