Swiss Broadcasting Corporation to pull plug on FM radio

Original Article ↗ Hacker News Discussion ↗

Audio quality and technical tradeoffs

  • Several comments question whether DAB/DAB+ actually improves audio quality; many broadcasters use very low bitrates (often 64–96 kbps), leading to audible artifacts and “metallic” sound.
  • FM can sound excellent when done well; DAB’s theoretical advantages are often undercut by aggressive compression and stuffing more channels into the multiplex.
  • DAB+ (HE-AAC) is seen as technically superior to legacy DAB (MP2) at low bitrates, but still noticeably compressed, especially for music.
  • Some note that in marginal conditions analog FM degrades gradually (noise, hiss), while DAB tends to work perfectly until it abruptly fails (“cliff effect”).

Reliability, coverage, and terrain

  • Multiple commenters say DAB reception is worse than FM, especially in cars and in mountainous terrain like Switzerland and Norway.
  • Others point out DAB’s spectral efficiency and single-frequency networks, but acknowledge this was optimized for more channels rather than longer range or graceful degradation.

Economics, spectrum, and rights-holders

  • One line of argument: DAB is optimized to maximize channel count and ad inventory, not listener experience.
  • Another: digital standards embed conditional access/DRM hooks, raising fears of pay-per-view radio/TV and recording restrictions.
  • Some doubt that DRM is widely used in practice and note that streaming services (Spotify, etc.) have already changed rights economics.
  • Future use of vacated FM spectrum is unclear; some expect it to be reallocated or auctioned, others doubt strong alternate demand.

Devices, cars, and user impact

  • Many still rely on FM-only car radios; adapters exist but are clunky and not free.
  • EU rules now push DAB+ into new cars, but vehicle lifetimes mean many listeners would be stranded for years.
  • Old, cheap, easy-to-build FM/AM sets are contrasted with more complex, chip-dependent DAB receivers.

Public broadcasters, fees, and politics

  • Swiss FM shutdown is linked by some to SRG/SRF budget politics: cutting visible services to influence an upcoming fee-reduction initiative.
  • There’s debate over mandatory broadcast fees, the value of independent public media, and whether state-funded outlets can be truly neutral.

Emergency use and resilience

  • Several posts stress analog AM/FM’s value in disasters: simple receivers, easy to re-establish transmitters, low tech dependency.
  • Digital-only broadcast and app-based streaming are seen as more fragile and more easily controlled or shut down.

Global comparisons and alternatives

  • Examples cited: Norway (FM shut down, many more digital channels), Germany (abandoned a 2015 FM switch-off plan), Ireland and Singapore (largely abandoned DAB), US HD Radio (often poor audio).
  • Some argue that FM + internet streaming is a better combination than DAB, making separate digital terrestrial radio questionable.
