petrolhead Posted November 12, 2015 Share Posted November 12, 2015 Rf spectrum analyser, best one for our game is the ism combo, goes from 150ish to 900someodds and 2.4ghz band. Great for radio surveys. You can also make your own by hacking a cheap dvb-t stick but the quality professional solution is not that dear.

cybergibbons Posted November 12, 2015 Share Posted November 12, 2015 https://www.coolcomponents.co.uk/rf-explorer-3g-combo.html They are good for the money. Fragile though - power switch and USB has broken on mine and it's always been taken care of. It will pick up most accidental sources of jamming, but miss intentional because of the slow sweep speed. A SDR is better to pick up intentional jamming.

cybergibbons Posted November 12, 2015 Share Posted November 12, 2015 A thing you plug into your computer, it receives a wide-ish bit of the spectrum (5MHz-100Mhz, typically), and you can show it on your screen as a spectrum or waterfall: http://nansupport.com/images/rfexplorer/heatmap-800x349.png Difference between the RF Explorer and SDR is that the RF Explorer sweeps - starts at 858MHz and slowly goes up to 878MHz, whereas an SDR can receive the whole 20MHz instantly. Just means you can miss things.
