ADSB SDR 'USB TV Stick' / Dongle Requirements
Supplemental to information found at https://www.flightradar24.com/build-your-own
(spurred from user finding stick information not so forthcomming)
If you do not chose to purchase a marketed 'ADSB stick' or USB TV Tuner via the suggested link there are specific requirements to be made aware of before purchasing generic sticks online
USB specifications
Must include (or be certain stick contains):
Realtek/RTL2832 chip
Rafael 820T/820T2 or E4000 (historic) tuners
Adverts that specify 'Fitpower', 'FC0012' or 'FC0013' are NOT suitable for ADSB
Refer table: https://osmocom.org/projects/rtl-sdr/wiki/Rtl-sdr
Likewise if FR24feed/Dump1090 show: Found Fitipower FC0012 tuner - You will not feed.
Standard or premium 'TV Sticks' that do not mention SDR(software defined radio), or the above key components specifically may not be suitable
USB RPi power Draw
TV Sticks often need external power booster to USB to keep some sticks 'alive' (USB power down) causing un-explainable errors. Likewise some extension USB cables can do this - an external 2-3Amp power supply is highly recommended before posting of issues.
IF you have a stick, and wish to check it's health. Or confirm the chipset types, there are a number of methods depending on OS/computer availability
How To Test If Your DVB-T RTL SDR Dongle Is Healthy Following two options are described below: OPTION-1: Dongle plugged into Raspberry Pi. OPTION-2: Dongle plugged into Windows Computer. . OPTION-1: Dongle plugged into Raspberry Pi. STEP-1: Install the test tools package rtl-sdr sudo apt-get update sudo apt-get install
NOTE: Feeding ADSB / FR24 is not USB task specific - It is only one of many other hobbiest projects the sticks are capable of
What is RTL-SDR? RTL-SDR is a very cheap ~$30 USB dongle that can be used as a computer based radio scanner for receiving live radio signals in your area (no internet required). Depending on the particular model it could receive frequencies from 500 kHz up to 1.75 GHz. Most software for the RTL-SDR is also community developed, and provided free of charge. Note that RTL-SDRs cannot transmit. The origins of RTL-SDR stem from mass produced DVB-T TV tuner dongles that were based on the RTL2832U chipset. With the combined efforts of Antti Palosaari, Eric Fry and Osmocom (in particular Steve Markgraf) it wasLast edited by Oblivian; 2021-04-05, 22:50.Tags: None
