Does it make sense? FrSky dual band receivers

Support my work   / pawelspychalski   FrSky tries to put something new on the market: the Tandem series TD R18 and TD MX dual-band receivers. They work, at the same time in 2.4GHz and 900Mhz! Of course, to pull it off, they need to be paired with Tandem radios like Frsky Tandem X20. On top of that, some people would like to see dual-band capability added to Express LRS. But, does it make sense?
