Re: [Elecraft] My radio all of a sudden is so loud it blew a speaker!

2018-01-28 Thread Barry 

Tom,
I can't explain the cause of what's happening. Rob and I ran into 
some craziness last weekend with power out and the antenna tuner. We 
fixed the symptom, but have been unable to trace the cause. In my case, 
I'm willing to swear that RF got in and corrupted the matrix of L and C 
values stored in the radio's memory, but I can't reproduce the symptom. 
What Rob suggested was to store off the radio settings using the 
utility, doing a reset, and put the setting back. That seems to have 
fixed the problem, so far. What is crazy is that of the set of K3 owners 
around us, only Rob and I seem to have had a problem. In the about 2 
years I've used my K3s, there has never been a hint of anything like 
this.

Hi
Yes 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

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.

Hi,
No the AGC is On.  It's still overall several times higher than I have 
ever heard when in High.
That's very strange since I always had it at high and when I first 
checked it was at High.
So now if I put it to low is is as it has always been. Putting it at 
high with AGC off, I will now blow any speaker attached!

2018-01-27 Thread Dave Cole (NK7Z) 
The dynamic range of the K3 is so great that this is possible, at least 
for an external powered speaker.


There is a setting in the menu for limiting the audio output.  While it 
makes the audio horrid, it does limit the levels, thus saving your 
speaker...


My guess is you have your AGC off...  I leave mine turned on, but have 
adjusted it to be as ineffective as possible, and only kick in on really 
strong signals.
