Looking for someone who has explored the controls of this radio because so far I haven’t found a Tone control on this radio. There is a hidden Engineering Menu for this radio which I have used to adjust modulation quality for the radio so it makes me wonder what all adjustment are in this Menu. Plus I wonder if there is a adjustment in there to improve the Receive on this radio. I spent a lot of time and money correcting issues with this radio and everybody says it sounds great on the air but it just needs a couple of tweaks to make it a good radio. I’m not the kind of guy who just stumbles around exploring because I might make a mess. But would like to know what all is in that Engineering Menu. And don’t get me started on President Radio’s Support system because it isn’t Pretty. LOL
