There is absolutely no issue with it. It is getting more difficult. For example today Harris and Motorola make mobile and portable radios that cover 33 to 966 MHz. They will work on every frequency in that range with any modulation you can think of. In the fleet I manage over 5000 radios. But there is a catch, you pay the manufacture to unlock the bands you use. We have several for the engineers and a few techs with all the ham radio frequencies opened up. Having said that just about every commercial LMR radio cover several bands. Example the VHF radios not only cover law enforcement, smr, aviation also will cover 2 meter. Same for UHF wil cover 70 cm. Many many hams will get their hands on a vhf repeater like a Motorola Micor or GE Master-II and convert to 2 meters. Anyone can do it legally, I use to do it a lot for a fee. You just have to be licensed to operate the PTT switch.
