Malahit : an interesting project of an SDR STAND ALONE RECEIVER 50 kHz - 2 GHz

Based on the RF tuner of Mirics ( the same as the RSP project )  it is a very interesting project of a standalone  receiver .

Being interested for a practical use in the FM Broadcasting band and in watching satellite signals converted in L band I asked my friend Paolo Romani IZ1MLL the courtesy to give it to me his Malahit for some practical tests 

I have made three video of some very rough tests .

It looks that there is a lot of room for improvements , in my opinion adding much more preselector or bandstop filters , and especially to have the possibility to have a grid of amplitude in dB on the screen and to have the possibility to avoid what looks a very good autoscale/AGC for a receiver and a panoramic look , but not for observing signals like tipical SDR  or spectrum analyzers .
