Once you have clicked on this waterfall button, you will be able to make the correct manual waterfall settings, which can be seen in the following picture.

It has WF plus the number of your zoom setting written inside it. The changes which you need to make are found on the right-hand floating box.ДЇirst click on the left-hand waterfall button under the big magnifying + symbol. You need to make the display as dark as possible, so that the display is not washed out, but not so dark that you canвЂ™t see the weaker signals. This will allow you to see many more weak signals. To get the best out of our Kiwi SDRвЂ™s you really need to change your waterfall settings to manual. These upgrades cost us a lot of money and took a lot of time to fit, but have produced some very big improvements on our 8 KiwiвЂ™s. So the only option was to break the ground loops by buying each of our 8 KiwiвЂ™s a brand new power supply.

They can produce most of their interference at VLF, which is impossible to eliminate with ferrite cores as the ferrite has no effect at such low frequencies.Д®ven though the earth-loop effects can be most easily seen at VLF, have no doubt, this interference will have been effecting you on all frequencies from 80m through to 10m. When earth loops are present, they cause lots of wideband noise, which can be seen on the waterfall display once you know what you are looking for. Our GPS repeater is used to lock each Kiwi precisely to the GPS frequency standard. This is to eliminate yet another route for earth-loops.Д®ach Kiwi also now uses its own GPS antenna which is fed via a GPS repeater into the radio cabin, this is once again to remove any earth loops. The latest upgrades during July 2021 were to give each of our 8 Kiwi SDRвЂ™s their own individual power supplies. The multicoupler receive pre-amp failed on Tuesday 17 August, causing all KiwiвЂ™s to appear very deaf. We will keep working on the interference problem until it is fixed, as we are sure that the interference is across other HF bands as well as 80m. With this tower down we had no microwave Internet links with any usable bandwidth as we cannot see over some of the taller trees. The main lifting cable snapping resulted in other problems with our massive tower winch, so the challenge got even greater. We replaced the towers guy wires last year, but not the lifting cables as they seemed fine. At the beginning of September our main winch lifting cable snapped as we lowered our tower while we were trying to locate the source of the noise bands of interference which have appeared across the 80m band.ДЄt times this interference can sit directly on 3615KHz which is exactly where the VMARS AM net operates, which is very unfortunate.
