Pretty much the same thing that the Zelscope link you posted does. That Zelscope spectrum analyzer is nothing like what Grogan is looking for. It is a cheap unit that is meant to look at a small low power RF circuit or audio source and certainly not an RF unit for 1-30 MHz. A real spectrum analyzer will cost thousands of dollars and will show hundreds of signals depending on the overall display width. It is also not really what one would want for seeing where the signals are because there are thousands of signals on 1-30 MHz at any time.I have used a spectrum analyzer connected to an antenna before and the result was :thumbdown: About the only time one would want to connect a spectrum analyzer to an antenna would be when looking for a source of interference which is what I was doing at the time. A wideband receiver such as Black Bart is far more usefull.
