A VERY IMPORTANT point!
I'm fortunate to have an Icom7300 with a visible spectrum ?display.
I ordered a handy smeter kit and am going to put it on the ubitx Mike input line to set the level correctly.
Now I adjust it based upon the icom display and until the power starts to drop on the wattmeter.
Too much definitely puts you on the ham bands at MORE THAN ONE frequency!
Wish I had a small low level measuring instrument handy.
Wondering if those little $90 "digital scopes" work?
