• i
  info: RadioDNS lookup name

  09710.d338.da0.fm.radiodns.org (frequency 97.10 MHz, PI D338, country code da0)

1. RadioDNS registration

• ✓
  pass: Registered

  09710.d338.da0.fm.radiodns.org points to the station's authoritative domain: pub.lkradio.net

2. Service discovery (SRV records)

• i
  info: _radiospi._tcp.pub.lkradio.net: not published
• ✓
  pass: _radioepg._tcp.pub.lkradio.net published

  priority 10, weight 10, port 80 -> pub.lkradio.net
• !
  warn: Only the older _radioepg record is published

  What to do: Add _radiospi._tcp.pub.lkradio.net 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

  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.
