Im hanging out alot on 10m doing what I can do and working band openings. Im new and educating myself as I go along enjoying my new hobby but I have a question on possible QRM or maybe the band conditions changing Im just not sure with the little experience I got so far.
Its seems daily at around 6pm 10meters goes south for me real fast like in the blink of an eye. I enjoy the low noise of 10m and do alot of data there but around 6pm give or take I go from a S0 on the meter to an S4-S5 of noise for no reason I can tell, kinda wiping out my JT65 for the evening all but for the stronger signals.
I just starting to realize a possible pattern but only today took note of whats going on I can also possibly show photos of before and after next time it happens. I am already aware of my known RFI sources or other anomalies and what they look like on my scope/waterfall, but this is mostly a whole band raise in noise level with a slight wave movement of the scope line. If interested can whip up a photo or video.
Wondering if there maybe an explanation out there? Am I looking at QRM or normal effects of day/night propagation changes?
Any help appreciated!
