so ive been trying to get more into DX chasing lately and someone at our club mentioned using the dx cluster spots to find active stations before i start spinning the dial. i set up an account on QRZ a while back mostly just for the logbook but i just noticed they have their own spot display on there too. and then theres dxwatch which someone else told me about and i guess there's also dx summit and a few others?

my question is basically — are these all showing the same spots or are they pulling from different networks? like if i check one am i missing something on another. also i cant quite figure out if the spots on qrz are real time or if theres some delay. sometimes i'll see a spot for a station and then tune there and the frequency is totally dead by the time i get there, which is either me being slow or there being a lag somewhere i guess

also is there a way to filter by band on dxwatch because right now im seeing everything and its a bit overwhelming when im just trying to work 20m mostly. still pretty new to all this so go easy on me haha

yeah they're mostly pulling from the same underlying cluster network but theres definitely some differences in how fast they display and how they filter duplicates. DX Summit (oh7rda.fi) tends to be pretty snappy in my experience. QRZ's spot page is fine but ive noticed it can lag a bit sometimes, could be a few minutes behind. DXwatch has good filtering options — if you look at the top of the page there should be band filter buttons, might be a dropdown on mobile not sure. once you get that set to 20m it gets way more manageable.

the dead frequency thing is totally normal by the way, dont get discouraged. a popular DX station can move or disappear in literally seconds especially if there was a pileup. some guys spot stations just as theyre signing off. you kind of learn to move fast or just accept youll miss some. it gets easier when you start to recognize the patterns of when certain dx is active

i went through the exact same confusion a few months ago when I started getting into DX. what helped me was just picking one and sticking with it for a while rather than jumping between them. I use DXwatch now and yeah the band filter is there, took me a minute to find it too. one thing nobody told me that i had to figure out — you can also filter by continent which helps a lot if youre specifically hunting something like EU or JA stations and dont want to wade through a bunch of NA spots you could work any time
