I have not had this happen with my K3s or my older K3.

I'm a little concerned about possible cone damage. That's why I am wondering if others are hearing the same thing.

I think my k3 does that. Didn't know it was a problem.
Find me on "Zello", a walkie talkie or handi talkie type app. I'm listed as KE5GBC. I'm mostly on late at night.

I'm running a K3s and have a popping noise through the external speaker when turning on the rig and to a lesser extent when turning it off. I recently changed speakers, thinking maybe a change would help, but the issue is still there. I'm currently using a TenTec 307B speaker. I've checked the cabling and terminals and tried a few different shunt capacitors across the speaker termnals. Does anyone else have a similar issue? Any ideas what to try next? Thanks.
