Weird imaging from 500 MHz++ on 100 MHz++

I dont see 187Mhz in this picture … what was the Lo set at?

think about this for a moment …

145Mhz X 5 = 725Mhz, im not sure what you mean “at the bottom”

I made a video about using the LimeSDR on harmonics of the Lo (Lo is a square wave signal)
Im sure your seeing the same thing … Harmonic operation

You should place a bandpass filter on your Lime for the frequency span your interested in …

I have these in hand … one for 2m, 1.25 and 70cm
