1. FCC won’t issue call letters if they don’t issue a license. They don’t want to identify and track what they don’t have to.
2. Making up call letters is a gray area. FCC probably won’t cry if you make up call letters in a format they don’t use for any licensed service, or at least are not used by any particular licensed station. However, you may be better advised to use a phrase identifier like Praize Radio.
