K2 Keying niggle

K4JQV
Cheers;

I have noticed that when keying my K2 with the crystal filter cinched (200 hz-400) and my audio filter ON in either mode 1 or 2 (the K2 analog CW filter) in certain situations I get an annoying pop or "pssst" sound when sending. I have serial no. 2676 QRP K2 that has had the keying mod performed. I normally use 5 watts with a .12 ms transmit/receive delay. i I built the audio filter to spec and it all tested fine. Any ideas on what I could do to mitigate this minor annoyance?

Jacob,

Try setting 8R Hold ON.  It sounds like it is set to NOR right now and
with your extended T-R delay, you are hearing the receiver unmute before
the delay time is finished.
See the K2 manual page 89.
