Switching power supplies are a common culprit for creating interference into the VHF frequencies. https://en.wikipedia.org/wiki/Switch...e_power_supply

Is the power supply OEM to that laptop or an aftermarket replacement. If not OEM, then that's the first thing to consider replacing. Or, you could bring along a metal container to drop it into and see if you can suppress the radiated emissions that are interfering with reception.

Other options include maximizing distance between that laptop and its power supply relative to the antenna or, perhaps, relocating them (or the antenna) so they are at somewhat of a right angle to the antenna.

Perhaps a new laptop?
