The LFRX has almost no gain, so you're limited by the noise floor of the ADC. In the USRP2, you can probably reliably detect signals down to about -60dBm or so. In the USRP1, you need somewhat more signal, about -50dBm or so. But those are ballpark numbers. But it depends on the details, and what kind of signals you're trying to detect, and whether you want toDear all, What is the lowest power of the signal that LFRX can receive? Really appreciate any of your help Yan
demodulate them, or merely detect their presence, etc. -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org
