#websdr — Public Fediverse posts

Just back from a 2 day binge-dive into operating a handful of different #WebSDR radio receivers, as a returning #radio #amateur. Picking up the hobby again after 20 years of parenting and jobbing.

Now waiting for #RSGB to get back to me, to hopefully verify the callsign I chose 25 years ago, so I can renew it.

Any #sdr fans aware of a web based tuner that supports #drm decoding, please?

#shortwave #digital #hamradio #websdr

#today I learnt that there are public web based #SDR services, that allow many users to remotely tune into a single wideband multimode radio receiver.

It's like having your own radio tuner, with a tuning scale several miles wide.

Been enjoying listening to radio amateurs using sideband, and shortwave radio stations from around the world.

I may not need to buy a SDR of my own so soon!

Here's one long list of web SDR's if you're interested:

Related to the above images is the web SDR at Hack Green. Something I've used to see my own antenna performance and listen to some interesting signals I can't get.

The VHF/UHF one picks up the nets Ringway Manchester sometimes mentions on his channel.

Today I found out: On 23rd April 2024, in Enschede in Netherlands, exactly at 16:55:09 UTC, the song Strawberry Switchblade: Since Yesterday started to play on 6130 kHz AM.

Status nach den ersten Wochen mit dem neuen Hobby:

#CBFunk aktiv, aber wenig los, meist geschlossene Gruppen, die sich persönlich kennen
#hamradio (#Amateurfunk): Derzeit nur Zuhörer über #WebSDR, aber angefixt, die Lizenz über die Bundesnetzagentur zu beantragen und die entsprechende Prüfung abzulegen…

I found a rabbit hole called #WebSDR through an article about the work of PT de Boer, one of my university lecturers at @utwente, who has been infuential for its development.

After listening to people from Twente discussing a.o. driving and taxes on FM, I continued a podcast with Sid Sijbrandij, a #UTwente alum, about "agentic everything".

The contrast between "doing things for the love of it" (#RadioAmateurs -> WebSDR) and "I want results" (Sid) felt sharp.

На сервер с WebSDR поставил ядро linux-rt. Почитал про такие ядра и подумал, что для обработки данных с RTL-SDR это подходит больше. Посмотрим, какие вылезут проблемы.

Только что узнал, что у OpenWebRX есть /metrics для того, чтобы prometheus и подобными снимать метрики. Пошёл рисовать дашборды. :)

Сегодня выходной взял и плотно поработал в сторону приёма на WebSDR. Судя по цепочкам маяков, приём стал куда лучше! Жду вечера, чтобы оценить работу Средних Волн.

Привет всем! Хотел бы сегодня поделиться этим WebSDR:

http://do6lsm.ddns.net:8074

Просто переходите по ссылке и кликайте на станцию!

Чем он примечателен: отлично принимает длинные и средние волны. У меня с этим большие вопросы, а вот там практически без шумов можно послушать музыкальные радиостанции. Иногда приём падает, но это, наверное, особенности приёма KIWI, я не знаком ещё с таким устройством.

Отдельно Михаэлю DO6LSM спасибо за поддержку этого приёмника!

Utah Hockey Club, 1280 AM on Northern Utah WebSDR Yellow. #KZNS Salt Lake City monitored from 80 miles north in Corrine, UT.

The KZNS 1280 web call is blacked out (because reasons? money? there's a way to pay for listening to hockey on the radio?)

Tied with the Maple Leafs with 5 minutes left in the 3d period.

KZNS is 50 kilowatts during the day, but only 670 watts at night. I hear another station underneath the hockey broadcast but the announcers win the contest.

TIL: The wide-band #WebSDR of the University of Twente provides waterfall diagrams for the whole day, plotting the station's full spectrum (0–29 MHz).

It's beautiful. 😍

#HamRadio

I learned about this part of the #radiospectrum called the #waterhole around 1400 MHz that could serve as an #interstellar communications band. I was sooo excited that I took a photo of the frequency from the movie and tried to find a #websdr with coverage in the band.
