The radio signals which are interfering could be shortwave.
I would recommend using ferrite clamps on the cables which do not carry digital signals, especially those in the most sensitive area, like from the hydrophone and pre-amp. Also the pre-amp power cable, if it is not battery powered.
*I think* preamp in this case is battery-powered. By ferrite rings you mean like those? https://www.ebay.com/itm/403346040770 And screen the pre-amp, if it is not in a metal
box. The pre-amp itself ought to have provisions for preventing this, like a low-pass filter at the input.
