I have a question about 300 MHz - ~ 400 MHz band allocation. Specifically; why am I receiving stereo commercial radio in the aforementioned band? There seems to be a simulcast for almost every station in the "FM Radio" band, however not necessarily in the same order. Using SDRsharp, I can see the spectral masks buttressing the primary broadcasting signal, as would be in the FM ( 87MHz -108MHz), and with the same (or better) clarity. Is this the HD Radio frequency allocation?
