checking if the ICAO address of the frame and the current item in the details view match. Slight refactor by placing the decimal to string conversion function into the string_format module. Added fix in the scope of issue #365 FrequencyStepView field in TransmitterView class FrequencyStepView field in TransmitterView class Update ui_transmitter.hpp Update credits Fixed left padding of the decimal part of the numbers.
