My SDR screen is awash with huge signals on 153-155MHz that don't even need the antenna connecting. These things bet together and produce these nasty spikes that seem to cross into the marine band - but they're not really there. A marine band radio on these channels with squelch open hears nothing at all - the SDR hears a nasty digital mush. Just a by product of a wide open sensitive wide band receiver.
