wideband LNA made by RTL-SDR

Post by P-40 Warhawk » Sat Feb 16, 2019 4:03 pm

The LNA that I bought from RTL-SDR , I think isn't working right . I am getting only + 2 DB gain out of it . I am pretty sure that I have it hooked up right .
Discone antenna to LNA in , than out +5 to the V3 dongle . Than in the SDR Device software check box bias T . I don't think I missed anything . How much gain should I see out of the LNA ?????????

Where are you turning on the bias tee on the V3 dongle?

Thank you moderator .
The problem is not turning on the bias T , it's that it's not turning off . Even without the HDSDR software not being loaded in the computer it's on . I think the logic chip that controls the bias T is fried . Well I guess that it's time to buy a new V3 dongle .
