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?
i don't think the SMArt has a bias tee for powering LNA.
You might get a RTL-SDR V3 dongle or a bias tee to power your LNA.
or you can get the whole kit from here:
My Outernet LNA does not light the LED either, but it does work.I think it is a manufacturing defect, pointed out in another thread as well (missing component).
he is using an SDR dongle which looks like doesn't support bias tee power at all:http://www.nooelec.com/store/nesdr-smart.html
Ok... for a homebrewer, that should be easy to fix.
Thanks @all, i will buy the dongle... because i dont want to use the chip. i need external storage and lan for my setup.
