Wide-Band WebSDR
- sciurus 5y agoThere's a lot of Web-accesible SDR's out there for 0-30 MHz. Here are some based on the KiwiSDR hardware: List: http://kiwisdr.com/public/ http://kiwisdr.com/public/ Map: http://rx.linkfanel.net/ http://rx.linkfanel.net/
- MandieD 5y agoThis one has SDRs running KiwiSDR, OpenWebRX, as well as WebSDR. I like KiwiSDR's interface the best overall, but OpenWebRX has better digital mode plugins pre-installed on most of the entries. https://www.receiverbook.de https://www.receiverbook.de
- dupontsr 5y agoAwesome!beats that old heathkit SW
- jamesbfb 5y agoGreat to see this here! I’ve spent an obscene amount of time on this and scanning my own SDR over the years.
- bdavis__ 5y agoBBC 4 on Long Wave. wonderful signal on 198 khz.
- PoachedSausage 5y agoIt is also a good signal to use for frequency calibrations as the carrier is derived from a Caesium reference.
- jcims 5y agoCaution. This is a gateway drug.
- anilakar 5y agoSoon you'll find youself listening to number stations and military comms, then geolocating them with help from multiple WebSDRs...
- ale42 5y agoAnd then you want to get your own receiver and antenna!
- MandieD 5y agoAnd then you'll get your license, because the Technician and even General US licenses are doable with a bit of study and can be taken online, by appointment with one of the clubs that runs exams.
- jcims 5y agoTotally agree. Not to be indelicate, but I passed literally studying on the toilet with a few ios apps. High school physics will get you a third of the questions, the rest is just rote memorization. If you’re going to go through the effort shoot for general.
- MandieD 5y agoI did it pretty much 100% brute force memorization with HamStudy, which was worth every penny of the $3.99 app price, and does a fantastic job of spaced repetition of the ones you got wrong or say “I don’t know” to. General is required for most countries’ reciprocal operations licenses (at “Novice” level, but most transceivers only do 100w without an amplifier anyway)
- mmaunder 5y agoIf you’re not a ham, try 14.100 mhz to 14.350 and set it to upper sideband. (USB) Also try 7.050 to 7.300 and set to LSB. It’s very busy right now with contesters trying to make as many contacts as they can in a short time.
- hun3 5y agowhat is it about?
- ale42 5y agoComment was about amateur radio (https://en.wikipedia.org/wiki/Amateur_radio https://en.wikipedia.org/wiki/Amateur_radio) and more particularly about contests (https://en.wikipedia.org/wiki/Contesting https://en.wikipedia.org/wiki/Contesting). The WebSDR receiver posted by the OP allows reception on 0-30 MHz range, which includes a number of amateur radio bands.
- CharlesW 5y agoFor anyone else who isn't sure what this is, from websdr.org: "A WebSDR is a Software-Defined Radio receiver connected to the internet, allowing many listeners to listen and tune it simultaneously. SDR technology makes it possible that all listeners tune independently, and thus listen to different signals; this is in contrast to the many classical receivers that are already available via the internet."

- ctoth 5y agoSet it to 4625 USB and listen to the creepy Russian Buzzer UVB-76. There has been speculation that this is part of the dead hand nuclear response system, though this theory has seemingly lost credence more recently. I also didn't notice any mention of it in David E. Hoffman's book, but no matter what it's actually for it is interesting and just a bit unsettling, especially late at night.
