So depending upon how far you want to tune your radio off then you can adjust the gain of that harmonic because I was doing an increase in the amplifier or decrease in the amplitude. So you can change that LO frequency to where it'll mix with your received signal you know to where now you're either 4 meg high and higher or low from the signal or 8 meg higher or low from the signal. So you can then adjust that amplitude and you know very"}
