HiYes but it's weird that never arose in the past. The one thing that IS different this time is that the radio had a full power down. Not just the front panel.... 73 Tom

Tom, Something comes to mind. Go into the setup menu and check the AGC threshold. As you move it up in number, the audio output goes up, and it takes a greater signal amplitude before it "kicks" in. I usually use this when using data A to prevent AGC capture, or at least as much, by other signals in the passband, for instance FT8 with a received bandwidth of 2.5KHz. Normally, the K3 AGC is excellent and should have prevented what you describe unless the the AGC threshold is too high. 73, Barry K3NDM ------ Original Message ------ From: "Tom" <[email protected]> To: "Elecraft" <[email protected]> Sent: 1/27/2018 6:24:40 PM Subject: Re: [Elecraft] My radio all of a sudden is so loud it blew a speaker! >Hi, >No the AGC is On.
