I have the same since I sent the rig to Elecraft for factory installation of the new Syn boards and "full tune up". The noise is as you say a crackling popping type noise
No idea Jim W6AIM -------- Original message -------- From: [email protected] Date: 11/30/2015 4:03 AM (GMT-08:00) To: [email protected] Subject: [Elecraft] Crackling in Headphones There are times that I have noticeupd a crackling sound in my headphones with my K3S. This is not the normal band noise static that has depth, this crackle sound seems very close to my ears. I first noticed it with my Heil headset and I tried wiggling the connection, changing the RX EQ settings and turning on noise reduction but nothing had any effect. It randomly comes and goes and I think I have also heard it on TX. I thought perhaps it was related to the Heil brand headphones. Last night I plugged in a new Sony professional headphone and the crackling sound was very strong for a few minutes and then eventually went away. I have never experience this with any other radio and I have no idea what is causing it or how to make it go away.
