Well that was a really easy setup and pretty cool that it's working #raspberrypi #flightradar24 #rtlsdr

@grant What sort of range are you getting?

With mine, depending on the direction, obstructions etc I get to about 160nm

Show threadGrantJun 28, 2023
@peter right now it says 38nm. The antenna is inside in my garage right now. And it's also the cheap one that came with the rtl-sdr. I need to mount it outside and possibly replace it with a better one.

@grant I got a proper one which is 1.2m from Pimoroni.

It's currently in the loft/attic - I should get that up on the roof at some point myself

Show threadGrantJun 28, 2023
@peter I may try putting it in the attic first. The wife is going to give me a dirty look if I start mounting antennas on the outside of the house.

@peter @grant From all of the antennas i tried so far, this one got the best reception. Unfortunately i don't have access to the roof.
Show threadPeter MountJun 29, 2023
@Patrick @grant the tin can is probably helping it as it's providing a ground plane for the antenna
Show threadPatrick Mortara Jun 29, 2023
@peter @grant 🤔 hmm, i just removed the can in order get an idea of how much of difference it makes and my message rate raised from around 365/sec to 410/sec, range seemed to increase as well a bit .... maybe i should ditch the can.
Show threadPeter MountJun 29, 2023
@Patrick @grant interesting it reduced it rather than improve it - might be something with the size of the can and the ADSB frequency.
Show threadPatrick Mortara Jun 29, 2023
@peter @grant strange. I clearly remember it improved reception when i installed it first time. anyway .... it's a never ending project! :-)
Show threadbitlevelJun 29, 2023
@Patrick @peter @grant Was it cloudy/raining at the time? That would affect reception.
Show threadPatrick Mortara Jun 29, 2023
@bitlevel @peter @grant no clouds this morning. reception still seems better without the tin can
Show threadbitlevelJun 29, 2023
@Patrick @peter @grant Sorry - I meant when you originally setup the antenna. 😃
Show threadPatrick Mortara Jun 29, 2023
@bitlevel @peter @grant that's like a few months ago, i can't remember the weather back then
Show threadPatrick Mortara Jun 29, 2023
@bitlevel @peter @grant removing the can was definitaly an improvement.

@peter @grant

I use the 0.6m colinears from Pimoroni/PuHut on my receivers - they work well for inexpensive antennas.

Have a look at www.1090mhz.uk and the live map at https://map.1090mhz.uk/

Perhaps consider sharing your ADS-B receiver with my system?

My feeder on GitHut at https://github.com/G8TIC/radar

@miketubby @grant I'll look into that,.

My system is a piaware one with the add-on to feed into flight24 at the same time, so if it's possible then I should be be able to feed into it.

It's been on my list to get a feed out of it so I can show on my own systems as well, so if it involves something in-between then I'll do that.

@peter @grant

If you're running on a Raspberry Pi it should be reltively straight forward...

has the code, drop me an email to [email protected] for a sharing key.

@grant What kind of receiver/dongle do use for it?
Show threadGrantJun 28, 2023
@Patrick I'm using the rtl-sdr from https://www.rtl-sdr.com/ and a raspberry pi. Flightradar24 has a simple image you can download and install on the raspberry pi
