7300 doesn't have UV, but there are common, watt-scale shortwave radios with UV that have been approved. The most common ones are likely the 991A and 7100.
Regarding a vehicle-mounted shortwave radio with UV capabilities, the IC-7100 is a good option. It has 100W of shortwave power and also includes UV functionality. The panel can be removed, making it more suitable for vehicle use than the 991A. However, it lacks some frequency bands compared to the 991A, but it's only approved for frequencies below 30MHz, and does not include 50MHz or UV. Whether you can obtain a UV license depends on local regulations.
However, it seems that both Japanese companies have failed to obtain approval for the 991A and 705 models, specifically regarding the 144 MHz and 430 MHz bands, as well as the 50 MHz band. The 7300 and 9700 models also lack approval for the 50 MHz band and 1.2 GHz band, respectively. It appears that both companies share a common problem.
