In the US, I don't think there was any commercial LW broadcasting (but I could easily be wrong). US-market radios rarely had SW bands and almost never had LW unless they were general coverage receivers. For the most part, the few times I looked through the band it was largely navigation beacons.
I was rather surprised to see an LW band on a regular clock-radio when I visited the UK, though that was 25 years ago.
- LeoPanthera 2y agoThere has been no commercial broadcast radio on the longwave band in the US, that's correct. That's why radios featuring that band are rarer here, and usually confined only to enthusiast radios. The WWVB time signal is technically inside the longwave band, at 60kHz.
- CalChris 2y agoNot broadcast, but there was marine longwave for point to point telegraphy. KPH would send messages to ships at sea at about 500kHz and it did broadcast news, weather albeit in Morse. It still exists as a museum and broadcasts occasionally. https://www.nps.gov/pore/planyourvisit/kph_treetunnel.htm https://www.nps.gov/pore/planyourvisit/kph_treetunnel.htm KFS still has a transmitter antenna farm in Palo Alto off 101 with a receiver antenna farm in Half Moon Bay. https://www.radiomarine.org/historic-coast-stations/kfs-san-francisco https://www.radiomarine.org/historic-coast-stations/kfs-san-... https://coastview.org/2024/01/28/kfs-high-frequency-receiver-half-moon-bay/ https://coastview.org/2024/01/28/kfs-high-frequency-receiver...
