Is a $35 SDR better than a $175 SDR?

- The ADSB Receiver Battle Royale continues. This time we pin up a NooElec V5 vs. an Airspy R2.
I'm using my fancy new power splitter and I have done everything I can to try and make this as even handed as possible.
Which SDR will win the bout?

Nice job Carlos. Love these comparisons.
Thanks Doug! 👍
Nice job, Carlos. I always enjoy when you do comparisons like this. In this case you've made a great effort to ensure that what each SDR device was seeing as far as signal / interfeference was as equal as possible. Thanks for sharing your findings!
Thanks! 👍
What you are really paying for with the AirSpy is the bandwidth, something you don't really need for ADSB. I guess one would have to decide if the extra 20% is worth the AirSpy premium. In most cases, money would be better spent on reducing feedline losses and getting the antenna in the clear.
There are also extra bits of DSP that aid in cleaner signals.
Thanks for this video 🙂
Glad you like it!
Fantastic work! I'm curious to see how the ADSBexchange SDR will stack up against the AIRSPY
We shall see, that is literally the data gathering I'm working on right now. ADSBx Orange vs AirSpy.
You need a preamp too.
I might add that to the mix but right now all I'm looking to compare is the performance of the individual SDRs on 1090MHz.
What is an SDR?
SDR = Software Defined Radio. In this case we are talking about a radio receiver that uses a USB port to deliver the sound of what it receives to a computer. I'm specifically focusing on airplane tracking using ADSB on 1090MHz.
ADSB - explained here en.wikipedia.org/wiki/Automatic_Dependent_Surveillance-Broadcast
Basically all commercial aircraft are requires to have a beacon that transmits data about their flight. Receivers on the ground can receive those messages and decode them to then see said details on a computer screen.
@@LifeAtTerminalVelocity Not interested at all. I have no idea about anything relating to "software". I don't believe computers and ham radio should be mixed. But that's just me. Everyone else in the world can do what ever they like. I'm just not into it. We're all stuck with computers now. But I don't want to have to use one to operate a ham radio.
To each their own. Though this video has nothing to do with ham radio.
@@LifeAtTerminalVelocity I guess not. LOL
