It's actually a mixer so now you can get a signal every four megahertz away from the frequency to where you can keep tuning up or down in frequency to actually get a different lower signal just because of the way the harmonics are. And the third one would be actually using the third harmonic because that puts you up into the 440 meg region to where now you've got a much weaker signal, particularly if your antenna is tuned for two meters at the same time because now of course you're listening to the 400. I've gone ahead and tuned up my HP's to where I've got the fundamental frequency and then also program in the adjacent channel is the third harmonic."}
