Turn on 5 volt(bias-t) power in an SDR

[LFBDBORDEAUX]

RTL-SDR v3 bias tee power on/off - 3 methods for 3 different installs

(1) Method for dump1090-fa Originally in 2017 Oliver Jowett (@obj) has proposed a method to turn on bias-t by adding a command in dump1090-fa.service file. https://discussions.flightaware.com/t/enable-biast-on-rtl-sdr-v3-before-dump-fa-piaware-start/20046/2 Subsequently in mid 2018 (1) Akos and (2) RTL-SDR Blog posted this method on their web pages. Both sites have “Credits” at bottom of their pages, and have given link to @obj’s method. http://www.radioforeveryone.com/p/piaware-with-rtl-sd…
