[Elecraft] Keyer Monitor Pop

[William Moore]

Greetings,

On my K2, serial 3842, using the internal keyer, I always get a key pop
sound but only on the initial make (the first dit or dah upon the rig
cycling from rx to tx). It is sounds  popping sound like a low frequency
click or thud. It particularly annoying  when using my Kenwood HS-5
headphones. My signal, when monitored on the air, is clean so the pop is not
transmitted.  Therefore, the problem must lie in the keyer monitor. Can
someone advise where I might begin my troubleshoot or offer a solution?

Thank you.
