I certainly understand the possibilities. I have noted that all of the sweeping signals fade in and out as they cross different frequencies, implying they're not being generated locally, but are subject to propagation effects. I'm no expert, but I seem to recall a receiving station has to be some di...

Why is that? HF propagation is magic, you know. You can bounce around the globe using milliwatts if the conditions are right. Conditions are only that right occasionally. Since I see so many sweeps, even when conditions are only marginal, I can only assume it's either that there are a lot of these ...

So either those things are incredibly common (to where I and the various WebSDR sites are always near some) or they shoot signals with a lot of power up into the sky. I'm presuming the latter... Why do they need a lot of power to characterize the ionosphere? And isn't it illegal to blast QRM all acr...

Before having an SDR with this wonderful waterfall model I used to hear the occasional sweep of a beat frequency and just figured it was someone from a nearby band tuning up or something. Now I realize that there are these frequency sweeps going on all the time across the HF band, usually ascending ...

Thanks. I read that article... Maybe what I don't know won't hurt me, since I don't really want to manage another separate antenna. The EF-SWL antenna I've set up is doing a great job, frankly, across the entirety of the RSP1's range. I'm quite often able to run the SDRuno IF Gain reduction all the ...

For what it's worth I just had a situation where the NB filter made a COMPLETELY unusable signal into something readable and actually quite clean. I found Trenton Military Weather, USB on 15.034 MHz, completely unreadable because our washing machine has a computer control board that insists on broad...

I have to agree. There are several feature couplings that there shouldn't be. And since it is software, it seems like they should be fixable. Another one is the Noise Blanking setting. IF Gain changes affect its threshold, when it would really be nice if there was some factor in there that would tak...

How, physically, do you bring antenna wiring to the Hi Z input? Just curious. It's fairly urban here and there are FM stations, several close by, completely filling the band - yet I'm not seeing a whole lot of what I would call FM "sproggies" or interference I don't think. Mostly what I see in the w...
