The LFRX has almost no gain, so you’re limited by the noise floor of the
long, I get very good reception of AM broadcasting and ham radio
traffic around 7 MHz. I was using USRP1.
Really appreciate your reply. The signal that is trying to be detected
is -117dBm, which turns out a larger amplifier is need in my case.
I have another question really need your help: how to corresponds the
amplitude set by program to the Vp-p of the front end output of LFTX?
Also the same question with receiver side, how to corresponds the
amplitude to the received signal Vp-p. The amplitude at transmitter side
is set by the program and at receiver side the amplitude is the one of
the signal after DDC.
Really appreciate your help
