I would Adjust the Power Out Level to see if it changes.

"Noise pedestal" applies to K3 or K3S with the new synthesizer. My K3 is old in the 2k series with the original synthesizer. 
It turned out that my signal was 40 KHz wide, with spurs every 700 Hz.  Embarrassing.

Search this forum for "CW Noise Pedestal" and read that thread.  In the thread is a link to a modification for K3 that added a capacitor to the fans that "could" be your issue".    Cheap modification from Elecraft and easy to install.    The problem I had with my K3s required sending it back to Elecraft to repair.   It came back and is working great.

Possibly wide signal on 80m

Ignacy Misztal
 

Today I was calling D2EB on 3521. Several hams wrote that my signal was S9 signal on 3524, a frequency of 9J2LA. 
I captured the signal by SDR-IQ. The spurs at about -40 db are about 4 KHz wide. What could be happening? 
My K3 is #2289.

Make sure you're using the right sound device, but also turn the volume up on it in the audio control panel *for the usb audio codec device* as you watch the waterfall.  I've noticed with recent versions of fldigi it seems a lot less sensitive than it used to be.  I have to turn it up for fldigi, and back down for wsjt-x.

Hi Jim,

I suggest you check the Config - Audio Card settings in Fldigi. From your description it seems like Fldigi is not listening to the correct device.

I am running Fldigi successfully on a 2019 MacBook Pro/Catalina.

Hi folks,
Can anyone help with getting fldigi waterfall to appear? I'm using a 2019 iMac, Catalina fully upated, with a K3S and trying to get fldigi to work. However, I get no waterfall and the signal in the lower right corner (barely noticed it) only jumps a few pixels on strong signals. WSJT-X works fine, decodes great, and the waterfall on it is perfect. I've got plenty of signal on the P3 also. Just sitting on 14.074 shows absolutely nothing on the fldigi waterfall. I must be missing something simple, but can't figure out what. Thanks for any help!
73,

Re: K3 Remote operating troubleshooting

Figured it out. I was misled when LSB switched to CW on transmit. I forgot that was normal. 

Actual problem was that compression was too high.

There is a major net on 7283.5 with over a hundred checkins at the same time. 7280 was clear.

K3 Remote operating troubleshooting

Dick, WN3R
 

Using K3 twins with RemoteRig. It’s been setup for 
years. Just got in the mood to turn it on. Works 
FB on CW. 

Transmit audio is a new problem. With or without mic
plugged in, as I advance mic gain, RF output
increases with no audio. I haven’t listened to it
yet on a separate receiver.  

Looking for anyone who experienced this problem 
and really good hints on the easiest way to
troubleshoot it. It would be wonderful  if i could fix it
without having all the remote gear moved to the shack.  It’s an hour trip between the station
and the operating position. de Dick, WN3R

That should be more reliable than 20M.

Re: K3s with K1EL keyer.

Issue resolved I was using color code on K1EL jacks. to install PTT and KEY inputs. Red on Red and White on White. Seemed logical  but....That was wrong.  Reversed plugs and all is well.

Thanks for the help. Joe, Pete et al.

While K1EL keyer chip in your keyer?

Have you checked the configuration to make sure you
have not swapped the PTT and key Output (assignment
of pins 3 and 5 - from memory)? Swapping those two
would make the normal CW output PTT and the normal
PTT output CW!

Thanks Gordon .

If it helps I have had a K1EL keyer chip fail on me. My keyer version uses the DIL device so I just ordered a new one and has worked every since.

 

If you have a battery installed disconnect it and remove USB lead then power it up again. Probably make no difference but worth a try.

Jim,
   The output of the K1EL keyer should be plugged into the"KEY" jack on the back of the radio, NOT the "PADDLE" jack.
That should cure your problem.

This tells me  there is nothing wrong with paddle or 1/4 inch male plug. I have no idea what happened  As a further check Iplugged paddle into  K1EL keyer sending QRS with my Fluke across the same  plug and there are indications of dots and dashes.

 I get same result keying K1EL keyer with paddle, N1MM or DXLabSuites.

Appreciate any help with this issue.  73, Jim K7EG
