ATC question
Greetings, just a quick question regarding transponder emergency codes 75,76, and 7700... with ads-b, if you insert one of these codes into your transponder, will atc see this distinct code or will they only see a nonspecific code where in you will have to verbally tell them what your actual emergency is? If the answer is the latter, it would be difficult if you've inserted 7600. Thanks to all in advance for offering your many insights.
fly safe,
