What is the best sdr you can buy that costs less than $100?

Fri Jul 24, 2015 2:19 am

What are some good software defined radios that cost $100 or less ($100 is about 91.11 Euros or 64.48 British Pounds)

Are all of the search engines down again?

I think you can get SDR running on a $10 USB DVB-T stick, like the RTL2838 ones that work with the Pi.

The gsearch thing will tell you how.

How is it that your Google works and discovers a useful link, but rpiswag finds it 100% impossible to use Google and prefers to post banal questions on here?

Would it be possible for people to play nice with kids/teen on this forum?
Or at bare minimum, just ignore their post?

Have you actually read any of RPISWAG early posts :?:

It could be the reason why some of the more active Forum Visitors become frustrated ;)

I read almost all posts on the forum, I just do not post that much.
and yes there are few many "noisy posters".

The point I was trying to make is (as an exaggerated analogy): If you were to take care of my autistic kid for a week, I could understand that at one point you would loose your temper and hit or verbally abuse him. But, that does not make it ok to do so. ;)

I would recommend using an R820T dongle!
They are in the $25 range, and are perfect for SDR.
My "maker club" called "revspace" is using them (as are many others), you can find some more info here:

"Best" depends upon your application. Do you need receive only or do you need Tx/Rx? How much do you value sensitivity and selectivity, etc? If you don't have a specific application in mind and you just want to get your feet wet with SDR, then they're practically giving away DVB-T usb stick receivers, so it's hard to go wrong starting there.

In any case there's a lot of info out there. e.g. http://www.rtl-sdr.com/roundup-software-defined-radios/

I would like the sdr to be a full duplex radio. An example of a sdr radio that is full duplex radio is the blade rf but is costs way to much for me to afford.

For you to transmit you will need either kit that can only be used within certain frequency ranges (unlicensed like 2.4GHz), or you require a license (AM, FM, amateur radio, etc.).

Please research the necessary license conditions before using any radio transmitter. These include, but are not limited to, passing a written test before obtaining the license.

I know you have to have a license but I already have a ham radio license. My uncle has a ham radio and he said I should get a license so I did. The ham radio spectrum is wide and the frequencies I need to use are in the ham radio spectrum.
