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.
7515 kHz: a #NewYearsEve surprise on #shortwave: Aqui Radio Andorra via Erevan/Gavar🇦🇲, 1900z all the way until 0100z! 😮 MASSIVE signal into UTwente #WebSDR 🇳🇱 Guess this might literally be the last SW broadcast from Gavar as its final regular client, Denge Gel, closed on Dec 1 😞 #NewYear2026
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.
ITS HABBENING!!!!! 15 minutes ago on UTwente #WebSDR, I heard a Polish CB op on 27060 kHz FM, checking in w/ other stations, local to him. Suddenly he started hearing DX too. Worked a couple. Gave QTH as KO13oe = Wasilków, ~60km N of me. He then QSYed to 26425 USB. #spaceweather #solarstorm
Radio World: The World Is at Your Mouse Click

Привет всем! Хотел бы сегодня поделиться этим WebSDR:
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!
Hackaday featured my recent article on making music with radio signals! Yay! :)

im internet gibt es viele #websdr server. meine lieblingsseite ist die der universität #twente . auf dem 40 m band um die 7,030 mhz finde ich rund um die uhr #cw aktivität. erstaunlich, wie viele menschen morsen können und wie schnell http://websdr.ewi.utwente.nl:8901/m.html
A tip: 6m is wide open, and as a 4-times-a-week live stream of a popular Polish HamTuber has finished, and one of its viewers noted PI4DX on 50139 USB calling North America, I went to CAMRAS #WebSDR in Dwingeloo, and... heard K2ZD snagging him 😱 Absolutely phenomenal! #6m #MagicBand #sporadicE
Two nocturnes - NOAA 18 and NOAA 19, near concurrent websdr recordings from the 25 meter radio telescope near Dwingeloo, The Netherlands
Flying to Hotlanta today for a conference. Decided not to bring a radio and to just tune around on websdr. If I have any free time, priorities will be learning about WSPR, WSJT-X & Olivia and desoldering SMD IC chips.
I’m receiving WSPR signals but my tx is not being spotted. Got a qrz-unknown callsign on a boat just north of Dominican Republic on the tropic of cancer yesterday!
Bob’s Radio Corner: Pairing a Phone or Tablet with a Radio

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. 😍
