When something like this happens only on a single band, it's more than
likely something has happened to the antenna or ground system. For example,
a trap may have arced over if you're using a multiband yagi; or it only
arcs over on voice peaks. Or if it's a monoband yagi, perhaps something's
happened to the feedline up at the antler that's not necessarily showing up
as a high VSWR. Once inna while, it could even be something entirely
unassociated with your ham station altogether, such as something like a
fence section that has corroded and is now resonating on the troublesome
band, regenerating RF that's causing the interference or possibly affecting
the antenna's resonance/VSWR only on voice peaks.
