Listening to 80m this evening, there is a strong intruder ( the ‘ Air Horn’ ?) on 3509 to 3514. It might be a good idea to operate above 3514 or below 3509 (for DX contacts) to avoid the noise. I don’t know if it is audible in VE or VK/ZL but this bit of info might help DX stations avoid this part of the spectrum. Above 3514 will I guess be busy over the weekend too.
