ADS-B for SDRplay RSP1 and RSP2 now available

I was very happy to see the following message from Jon Hudson at SDRplay this morning:

“ADS-B for both RSP1 and RSP2 is now available for the Raspberry Pi 2 & 3 – you can get the software from downloads – http://www.sdrplay.com/downloads

If you are an RSP2 user, make sure you use Antenna Port B when running ADS-B.”

This is great news as I’ve had a number of readers ask if the RSP series SDR was compatible with the DUMP1090 ADS-B system.

The SDRplay RSP2

If you have an RSP1 or RSP2 and either a Raspberry Pi 2 or Pi 3, this will be an easy, accessible way to experiment with ADS-B.

In the long run, however, I’d never devote an RSP as a dedicated ADS-B feeder. Why? The RSP is a very versatile, full-featured SDR and I wouldn’t want to tie it up with such a relatively routine, simple task.

Instead, I’d give ADS-B a try with the RSP, and if I liked it, I’d purchase this inexpensive FlightAware RTL-SDR dongle with a built-in 1090 MHz bandpass filter for $18.95.

I’m always so happy to see such active application development from “Mom and Pop” companies like SDRplay and AirSpy. Just more ways to put your SDR to work for you!

Buyer Beware: Insane RTL-SDR pricing

$300 is an absurd price for this RTL-SDR package.

This morning, while browsing eBay, I noticed a high-production retailer selling an RTL-SDR package for $300 US! (To add insult to injury, this isn’t even the latest version of the RTL-SDR dongle!)

I post this warning message to those who are new to the world of the RTL-SDR.

You should never pay more than $30 US shipped for the latest version of the RTL-SDR dongle unless you’re buying custom enclosures, filtering, etc. In fact, the RTL-SDR package above retails for about $25 shipped via Amazon (though currently out of stock). The RTL-SDR stick alone retails for $20.95 shipped. You can find a number of models between $10-20 on Amazon and eBay.

The majority of eBay sellers list the RTL-SDR at the proper market price.

The allure of the RTL-SDR is its affordability–don’t fall for sellers on eBay, Amazon or elsewhere who list these at outrageous prices.  They’re simply trying to rip you off.

Many thanks to SWLing Post contributor, Rafman, who shares the following photos that were originally posted by Alberto (I2PHD) on the Elad email reflector. Alberto noted:

“Here it is…. shown for the first time today at the Montichiari Ham Fest. Price TBD….”

Many thanks, Rafman, for the tip!

We’ll continue to post FDM-S3 updates as they become available. I will also plan to review the FDM-S3 when it hits the market.
