Alinco have a refreshing-benefits free download on their site where you can download software to program the DJX-7 that's very nice of them. Computer programmable. The only drawback I see is that you can't have descramble mode and a CTCSS tone in refreshing-benefits use at the same time it's one or the other. For me this is a selling point for this scanner.
Apparently on the Alinco DJX2000 this function is not available on a per ch basis but with the DJX-7 I am pleased to say it is. refreshing-benefits The Inversion feature on the DJX-7 allows you to select an inversion point that matches the one used by your target user and turns it into audible speech again. These signals are then inverted to a particular point. Inversion scrambling is used by mixing the high and low points of the human voice and turning them upside down (I read this somewhere else please do not ask me to explain in full) which refreshing-benefits makes speech undecipherable to the human ear.
