Look very local to you. 156.0 is probably one of the worst frequencies for low power interference from power supplies. The cheap unfiltered switch mode psus are a killer! My internet router was replaced my talktalk and shut down channel 0 in my office, until i found it and put the old power supply back. My journey to the office in my van is a noisy one. Three houses i pass in walking speed traffic have enormous amounts of noise, and one does have music quietly in the background. Probably plugged into a powered speaker. Knock on doors within 25m if the neighbours are friendly. If the interference has only just started, i bet one has had a recent delivery.

it's been going on for a month now, thankfully it's brief and only every few days or so.
