How you get shortwave radio via Internet.
« on: January 22, 2019, 01:53:47 PM »
Not what I thought.  :o
I thought it would just give me webs sites for the few broadcasters who do live audio streams over the internet. I could hardly only imagine a literal way to  tune the band and listen and pick what I want to hear. It is true!

It is Web SDR. A Software Defined Radio connected to the Internet. There are lots of them allover the world. You can listen to actual raw shortwave recited in  Europe or even form California.

Again, it is not streaming form the broadcasters, rather it is  raw shortwave reception form a specific location in the world.

I recommend this if you want something different  just steam from major broadcasters. It is a real SW receiver from another place in the world.

The technology is mind boggling! It is a real-time spectrum analyzer and you can select center frequency and a audio feed from a specific frequency using three or four types of demodulation. And variable bandwidth both the spectrum range  and the demodulation. And a volume control, of course.

Check it out!

Neat stuff Geek... was playing around at this site http://69.27.184.62:8901/

I like that they show full bands and a graphic of where radio transmissions are happening in a time lapse graph and so you can see what frequency has a transmission happening and click and go to it.

25 years ago I had a ham radio without a FCC license  ::) and I just listened a lot and a couple times would get in on a conversation. Also had an old Norelco Short Wave Radio ( guessing a 1960s model which I remember said Made in Holland on the back of it )which was blue plastic body with white plastic knobs and the pressed paper fiber board back to it. It was an old tube radio that I picked up at a yard sale for $5 but it worked awesome for pulling in some far away signals with the antenna that I used which I would disconnect my ham radio and connect the old short-wave radio to this 20 foot antenna on roof of my house.

These days I have a modern hand held Radio Shack AM/FM/SW/Weather radio that takes 4 AA batteries and has a scan for picking up on signals, but its not as good as that old Norelco I had.

The closest thing I have seen to what you shared was a USB Stick that was sold about 10 years ago that was an Internet Radio Device, where the device basically when connected to a computer would launch a program that gave you access to streaming audio broadcasts all over the world so I wasnt stuck with just whatever my radio could pick up in New Hampshire USA because whatever radio stations around the world that had a streaming service that were added to this device I could connect to without a weak signal.

Saved this page for future use to listen in on different radio transmissions.

DaveLembke,
Glad you enjoyed it. It brings back old memories of my adolescence. Rather than learn how to talk to girls,I learned Morse code. and got a radio license.  :D

Here is a long list of receivers all over the place.
https://skywavelinux.com/best-sdrservers.html
Don't let the Linux reference mislead you. The sites listed work well with Windows. The software is web based and does not require yu to have a specific OS.

Here is one in the UK:

Another located in Pennsylvania, USA.

Japan:

New Zealand:
http://kiwisdr.jks.com:8073/
Here is CA3PBR, Santiago, Chile.

Washington DC, USA:

WebSDR, Montevideo, Uruguay
(South America)
http://201.217.131.106:7900/

Bear in mind some will default to the  shortwave band. And you will hear static until you tune to a frequency with a good signal. Others will default to local AM broadcast. This is a great way to hear local dialogue in other countries.  :)

Alain, this is not a stream from the studios. It is a linefeed of a Web SDR that you can tune to a frequency of your choice.

Re: ... shortwave radio via Internet Rasberry Pi.

Software Define ed Radio.

It can be done with a Raspberry Pi. Up to10 people can listen, each on a different frequency in the selected band.

There is so much information about this!   

Here is a nice video that explains the WebSDR thing
https://www.youtube.com/watch?v=xYopqVS2vAI

Again,  It  is not studio streaming. It is a real radio that has a real antenna.
Has anybody here even installed one of these?

I've actually done a fair bit with this sort of stuff, not done it for a while due to being busy with other stuff but it's really fun stuff to play with.  So far I own an SDRPlay, HackRF One and a basic RTL dongle.  They are pretty good to play around with and to get started, a cheap RTL dongle can be picked up for under £10, they are sold as TV tuners but work as SDRs while costing very little.  Not all of these will do HF frequencies (shortwave) particularly well out of the box however you can use an "upconverter" (I use a ham-it-up) to shift the lower frequencies up into the range of the SDR tuner.  Only danger is that it's pretty addictive, you'll buy a cheap RTL dongle then end up spending a fortune on different SDRs and antennas.

A couple of years ago I was able to use the SDRPlay hooked up to an antenna built from bits of 15mm copper pipe to detect radio signals reflected from a meteor: https://twitter.com/camerongray1515/status/764560131111747585 - pretty fun!

Yes, you can buy a low-cost dongle and use your computer as a Software Defined Radio.
But, as you said, make sure its  the shortwave range,if that is purr desire.
Amazon has them.
Also,to be effective, you need an outdoor antenna.The diagram below is more complicated that necessary.  Just any kind of wire of about 10 meters or 33 feet should work good enough.  Anything. Even some wire stripped out of n old Ethernet cable will do.  Just bare the end of the wire and stick it into the connector. You do not really need coax. Contrary to what people tell you, coax only works if you have transformer**, which adds to the total coast.
** A Balkan for shortwave. It can cost more than the dongle.
