Thanks for this comparison. They're both pretty close . I have the duo also , I use it for DSDPlus to decode digital audio at the moment . I have used it for a scanner (1 rx for marine the other for airband). I like the filters , it's pretty good to play around with. RX-888 is also a good choice if you have the computing power for viewing massive chunks of the ham spectrum in real time Thanks for sharing your comparison. Great video 73 Rab de mm7bvp
