Hello to everyone,
Is a SNR of 1.4 - 1.9 dB without a LNA possible?
My complete setup:
RPB 3
DX Patrol MK2
Homebrew l band patch antenna
I ordered the following LNA:

Hope it is ok for receiving a stronger signal, I heard I need at least 3 dB.
BTW: I’m aware of the LNA4ALL.
Thanks!

Is there any way to set the rf gain?
Because I need to adjust the rf gain for the dx patrol sdr device.
I’m already connected to the pi with ssh but I can’t find a config.
Thanks…
most probably it doesn’t work as a wideband LNA and picking up all the surrounding noise too. the outernet LNA has a narrow bandpass filter (SAW filter)
gain in the Skylark system is set automatically
