Faint clicking sound in headphones
Locked
 
|
Just today I notice a faint clicking noise when using my headphones and only when the AF is turned up not when all the way down, here is my setup.....Elecraft k3, Begali key into a Winkeyer USB and the menu key weight setting in the K3 is 1.10
Here is what I have tried to fix the issue with no success: 1. Tried different headphones. 2. Snap on chokes on headphone cord. 3. Removed Winkeyer and plugged key into rear of K3. 4. Tried a different key plugged it into Winkeyer and just to rear of K3. 5. Tried on Dummy load and clicking is gone. 6. Check all connections to make sure they are tight. 7. Tried my KX3 using same key and antenna and no clicks. 8. The clicking is happening on all bands. I believe that is all I tried and I am at a loss as to what it could be, I'm hopping it's something simple that I have overlooked.

Hi Mike,
I know that the same thing can happen on older KX3's when they are connected to a serial port running rig control softwarte. On the KX3, Elecraft can supply a small bypass cap to rectify the problem. I'm, not sure if that's the issue here but try the same and make sure the serial port cable is not connected to the K3. If it is the issue, call up Elecraft. They will probably suggest the same thing as on the KX3. 73 Tom va2fsq.com -----Original Message----- From: Mike Weir Sent: Monday, January 25, 2016 10:44 AM To: [hidden email] Subject: [Elecraft] Faint clicking sound in headphones Just today I notice a faint clicking noise when using my headphones and only when the AF is turned up not when all the way down, here is my setup.....Elecraft k3, Begali key into a Winkeyer USB and the menu key weight setting in the K3 is 1.10 Here is what I have tried to fix the issue with no success: 1.

I hear something which is very slight in QSK mode but not in SEMI mode.
My observation is that it is "very" slight. Headphones with higher sensitivity may be more prone to exacerbate the the click. I speculate it is the leading edge AGC recovery in between CW elements. Being on a dummy load, there would be no AGC transition to noise as would appear with noise from the antenna. If you think it is RF related, turn the PWR down to 1 watt or operate in TEST mode. I suspect however it is switching related and not RF related. 73 Bob, K4TAX On 1/25/2016 9:44 AM, Mike Weir wrote: > Just today I notice a faint clicking noise when using my headphones and only when the AF is turned up not when all the way down, here is my setup.....Elecraft k3, Begali key into a Winkeyer USB and the menu key weight setting in the K3 is 1.10 > Here is what I have tried to fix the issue with no success: > 1.
