Ok so if your Wouxon listen perfectly to two frequencies, it is because it is a true « dual band » radio, not a « dual watch » type of thing.
So then you don’t need anything in the sort of « dual-watch ». You need a *real* « dual band » radio that can do V-U / U-V / V-V / U-U.
A few real dual bands radios I can think of are higher-end Icom IC-92AD, ID-50 / 51 / 52, Kenwood TH-72, 74, Yaesu VX8, FT2D, 3D, 5D, etc.
But all these are *ham* radios, covering VHF / UHF ham bands, and you’re looking for commercial bands, so…
yes, the double standards (ham and commercial) Chinese products that can do real dual band monitoring like your Wouxon seem to be your only choice.
