How to get yourself a cheap wide band receiver radio for less than $50 AUD, but there is a catch!

[Szymon]

Hi Guys,

Would you like to receive shortwave radio from both AM and SSB stations?

Would you like to receive SSTV from the space station?

Would you like to receive weather images from satellites?

Would you like to receive aircraft transporter data from overhead planes?

All you need is a USB SDR dongle with the appropriate antenna that is connected to a computer that is running free software.

So what is SDR?

https://en.wikipedia.org/wiki/Software-defined_radio

Back in the day. Someone accidentally discovered that the DVB-T USB dongle (device for receiving TV signals and feeding it to the computer via USB) can also receive a wide range of frequencies that was the day when SDR exploded onto the scene.

The cheap SDR technology has moved on since then and now you can get cheap SDR receivers from Aliexpress. Here is what I purchased recently.

So what's the catch? The SDR receiver requires an antenna and a computer with the appropriate software.

If you're interested in this thread please let me know below.

Cheers Szymon

Software Defined Radio (or SDR) is one of those things that I never knew existed as I was getting into the radio hobby. After learning about it, it's one of the coolest radios in my humble communications arsenal.

In this video I want to introduce you to SDR, and share just the slightest glimpse of what it has to offer in the hope that it inspires others to get into it and learn more.

Excellent Post by John.

Here is how you can decode the SSTV (Slow Scan TV) from the space station, using any 2m 144mhz receiver with a phone app.

• @-Tris- quote:

"Someone discovered the world of SDR 😁 You will have a lot of fun with it😉
Not a pro myself, but some tips: If you can, get your antennas outside. That's always the best option. Build or buy a 2m ground plane antenna. You can transmit on it, and they are great for listening to FM Broadcast, aircraft voice, ISS, NOAA weather satellites, 2m ham band, maybe there is something on 4m in your region. And a 1/4 wave 2m antenna is also a 3/4 wave 70cm antenna, so there is even more to receive with this one antenna. To improve reception, filters and maybe an amplifier can help. I still haven't tried decoding weather satellites myself. I like the idea of having a camera in space and getting the pictures directly from it.

For shortwave, get a magnetic loop antenna like the MLA 30+ or YouLoop for example. Fldigi might be an interesting program for you to decode some stuff. But there might also be more modern software, not sure, it works for me.

And just as I'm finished writing, the ISS is nearby. Listening to the repeater right now 🙂 "
