To all with the crackling sound, I had that problem with AM broadcast. I enabled the AGC, and the crackling went away. No issues right now.
YMMV! '73 de JIM N2ZZ -----Original Message----- From: Elecraft [mailto:[email protected]] On Behalf Of Brian D. Comer Sent: Monday, November 30, 2015 6:41 PM To: [email protected] Subject: [Bulk] [Elecraft] Re Elecraft] Crackling in Headphones I have noted a similar Cracking in the speaker when listing to AM broadcast station KFI (640 KHz). At first I assumed it was just overload as I was using a 160 meter dipole and the signal strength meter was maxed: however moving to steppir antenna tuned to 40 meters gave the same result with and smeter reading of only S9. I have a local AM station on 1450 KHz that produces a -10 dBm into a spectrum analyzer and -30 dBm on the P3. I had assumed from this, without making any further checks, that the receiver was just overloaded. The cracking sound does not sound like any dynamic range problem I have heard before but I have not taken the time to make any serious tests. I make these comments because I am not convinced this is any form of overload and wonder if it could be related to your problem. 73 Brian KF6C.
