Hello I've tried to receive 7 MHz ham bands with LFRX. As expected, after reading the mailing list and documents around, I realized that without a steaming >40db low noise preamp ahead LFRX, there's very little to listen to (although I managed to listen some broadcast on 7100 - 7200kHz with antenna inside the room, which is under a concrete roof).
Now, since I need to prepare a demo with USRP/GNURadio right on the 7MHz ham band, is there anyone out there who can point me to the *fastest* solution to homebrew a low noise >40db Preamp? Of course there are lots of designs on the web, but I need something effective and fast to build from sombody who tried by personal experience. Thanks in advance Alberto. _________________________________________________________________Su Tiscali Photo c'รจ il FUORI TUTTO !
