I Have an old galaxy dx959 that has a bipolar finals, it is actually pretty stable, but I leave it turned on for an hour before I try and talk on it. The clarifier is still unmodified on it. I’m hesitant to unlock the clarifier on it because I feel like it will turn it into a drift monster. I’ve never owned an export galaxy. All I’ve ever owned are the 949/959 radios, two purchased brand new, and the one I have now was used. But all three were very far off frequency when I got them.
