BD3OZV Regarding changes, at least in Shanghai, the prerequisite is that all your equipment must be on the same frequency band. If you have different bands, you need to apply for each one separately. For example, if you have 2 UV handhelds and 1 shortwave radio, you will need at least 2 licenses. You cannot combine the shortwave license with the existing UV license. Of course, it is also possible to have one license per device; having 3 licenses would not be a problem either.
