There is another tool the amateur can use to view large swaths of spectrum:? The SDRPlay.? I was recently made aware of a spectrum analyzer application made for the SDRPlays by Steve Andrews.? In the past, the SDRPlay line-up of products has not necessarily been my favorite, but this app has finally moved my RSP1A off the shelf.? Steve's SA application is really outstanding and well beyond the capabilities of the SpectrumSpy for the AirSpy products.? Possibly that is why SDR# no longer offers SpectrumSpy?? Believe me, it's spiffy!!? I'd encourage anyone requiring more than 8 MHz of on-screen spectrum display to give it a try.? And it covers all the way down to the submarine comm band and below to almost "DC" without an external converter.?

But filter in front of my kiwi does solve most of the problem.
Yes now you have the filter fitted, it looks like the loop seems to be performing OK with regard to overload.
The rest of the interference looks like it's general noise and hash from switched mode power supplies, computers and other IT equipment or similar.
You may not have noticed this before, but the ability to 'see' 30MHz of spectrum with the KiWi, makes it much easier to spot wideband swathes of noise, that may previously not been so apparent when observed in a narrower bandwidth.
It was quite an eye opener when I got my first KiWi, as I thought my site was electrically quiet, but the waterfall and spectrum display told me otherwise.
