PR40 (Dynamic mics) and 6400

Alright, I am offically a lid. After 50 years of ham radio I could not figure out why my PR40 was hissing. Then I realized it is a dynamic mic and not electret. I was putting bias on the mic and it hissed, unsurprisingly. Once I turned the bias off, presto, perfect audio. Don't make the same mistake I did! By the way, there are mic profiles that work amazingly well with the PR40 and you don't have to find the settings for yourself (which is a real pain). Minor adjustments are all that is needed. Don't forget to rename the mic profile, though.
