I build a diy-receiver with raspberry pi 3, NooElec NESDR SMArt (https://www.amazon.com/NooElec-NESDR-SMArt-Enclosure-R820T2-Based/dp/B01GDN1T4S/ref=pd_lpo_504_bs_t_2?_encoding=UTF8&psc=1&refRID=A4F0C9RE0YS4NT7TGVBJ), NooElec-Amplifier (https://www.amazon.com/NooElec-Amplifier-Outernet-Inmarsat-Applications/dp/B01L8E9QTW) and the Outernet Antenna.
The LED on the Amplifier doesn’t go on. i tryed “/opt/sdr/rtl_biast -b1” but i got “undefined symbol: rtlsdr_set_bias_tee”. So whats going on? The wifi (dongle), software on the rPI and the RTL-SDR working; tries to find a signal. but since the led is of on the amp i think the rtl-sdr doesn’t power it on :(. but why? and how can i fix this?
