No? Well now you have! There's 26 of these little beauties spaced 312.5kHz apart on each side of the center marker. You can see the marker delta of 310kHz (resolution wouldn't let me be as precise as 312.5) showing the first subcarrier peak to the right of center. This one is special, in fact. It is one of 4 pilot subcarriers spread among the 52 total, leaving 48 subcarriers for data transport. This picture only shows 10MHz of the spectrum since it's hard to see the full bandwidth at this low resolution of 1001 pixels horizontal. This has been your neat fact of the day. --Bart
