Ooops, I should also have added this YouTube link which shows you how to use them.



Although this shows them being used with a printed circuit board, you can do the same thing with power supplies, cables, PC's etc.

Just be aware that the KiWi takes time to process the signals, so there will be a delay of 1-2 seconds between you moving the probe and seeing a change occur on the waterfall or spectrum display.

Yes, unfortunately you have two massive AM broadcast signals on 760KHz and 800KHz.

As a temporary measure try attenuating the input signal by about 10dB.

A longer term fix is to build a notch, or high pass filter to reduce the level of the BC stations without reducing the level of other signals.

Some notes on the subject can be found towards the top of this web page.

I'm quite pleased with this one, especially as it's an HF signal and there are not that many suitably placed KiWi's.

It's a Russian CIS-12 signal on 11175KHz.
