You may be mistaken.
Depending on what country you live in, the rules can vary. If you are in the USA, FCC Type Acceptance is something you need to consider. The FCC Part 80 (Marine radio) rules require that all radios used in the service have a Type Certification for Part 80 use. 80.203 covers that:
Electronic Code of Federal Regulations (eCFR) published by the Government Publishing Office
www.ecfr.gov
Radios intended for use in the amateur radio hobby rarely have any type certification on their transmitters, as it's not required.
"Commercial" radios often only have Part 90.
A -lot- of the cheap Chinese radios have no type certification.
So, depending on exactly what radio you are using and where you are using it, it may very well be illegal to program those into your radio.
