Airspy R2 and PI 3 B+


#1

Continuing the experiments. I having been looking at the Airspy R2 for comparison/testings. Firstly, why don’t these companies have reasonable manuals for such models??? Anyway, although I can not define instructions like, connect Airspy to your antenna, connect power supply to Airspy, connect a USB mini cable from the Airspy to a PI 3 B+ USB port, install Airspy server, if running PI 3 exteranally, install appropriate ADSB 1090 scripts etc.

Now I take it, that the Airspy connects to the PI 3 via a USB mini cable to a USB port in the PI 3 and you then go from there…

Not sure how or why you would use airspy server for ADS-B.
I find them deaf without an amp like the hab-nevus/uputronics amp/filter.

or in the U.S. from https://v3.airspy.us/product/upu-fp1090s/

Good luck. My airspy easily over runs my RPI3s. I upgraded to an Odroid XU4.

I followed this setup from
https://airspy.com/quickstart/

Standard setup (non FlightAware)
The whole process for setting up a high performance ADSB receiver has been simplified. For the Raspberry Pi 2 or 3, Odroid or Pine64 boards, you can use the following commands:

mkdir airspy
cd airspy
wget https://airspy.com/downloads/airspy_adsb-linux-arm.tgz
tar xzf airspy_adsb-linux-arm.tgz
sudo ./airspy_adsb -l 30005:beast -l 47806:asavr -c sdrsharp.com:47806:avr -p -w 4 &

FlightAware Integration
The easiest way to integrate Airspy into an existing FlightAware PiAware system is to feed dump1090 through its “MLAT result” port.

mkdir airspy
cd airspy
wget https://airspy.com/downloads/airspy_adsb-linux-arm.tgz
tar xzf airspy_adsb-linux-arm.tgz
sudo ./airspy_adsb -c localhost:30104:beast -c sdrsharp.com:47806:avr -p -w 4 &

You might be right re the airspy server, just looked at a lot of things and there was one diagram of a PI3 setup, going to your PC and then to others. My would only be coming down from the mast to my PC. From your posts and just looking at the Odroid XU14, that would be the way to go if using an Airspy R2 and I like the fact it does have a gigabyte RJ45 connection. Lots of script support here and should also be able to run 1090 mutability setup??

quick one. On the US store of Airspy, it states the R2 is out of stock due to redesign, is there a new version coming out of the R2??

Jon, I found that reference to Spy Server:

What is SpyServer?
SpyServer is a free RTL-SDR compatible SDR server that is designed to work with the popular SDR# software. It is actually designed for the Airspy range of products, but the author has also made it compatible with RTL-SDR dongles. Running a SpyServer allows you to connect to and use a remotely positioned RTL-SDR over a network connection (such as a local LAN/WiFi or the Internet). Once connected, using the dongle is the same as if the dongle was directly connected to the users PC.

Remote servers are useful as you may want to set up an antenna in a remote location (such as up on your roof or shack), and don’t want to run a long lossy coax cable down to the PC. Instead you could run Ethernet cable, or avoid cables by using WiFi. All you’d need is power for a remote computing device like a Raspberry Pi 3. Perhaps you also have a great antenna location at a friends house, or other property and want to access that antenna remotely. Or maybe you want to use your radio while travelling.

This was from RTL-SDR.COM. This will be how I will be running it, from the roof.

I know what it is. I don’t know why you would bother using it for ADS-B.


#7

I’m curious to read about the advantages of using a more expensive receiver for ADS-B.


#8

If and when a re-designed R2 is released, you can use the AirSpy Mini. Same specs as far as ADS-B is concerned, unless you have some additional requirement that needs the R2.


#9

There should be a few back in stock soon according to this on Twitter a few days ago:
