There's a much easier and much better way to "do it by yourself".
I use a free application Audacity for the process. Connect the K3 to
the computer using the same method as for digital modes. Activate the
K3S in the TEST mode, turn up the MON gain to about 10 and activate
the record mode in Audacity. Record about 30 seconds, save the file
and play it back. Listen critically.
This is NOT representative of what is heard on the other end because it
doesn't include the TX SSB roofing filter.
A general comment overlooked by most. The mike-to-mouth position and
mike placement is much more critical than many realize. I've found if
one changes the mike-to-mouth distance, looks around the room or the
desk while talking, or doesn't put the headset boom in the exact same
place every time, one will have different sounding audio. Thus it may
sound great one time and not so good the next time.
Yes, this IS significant. Many mics (the class called cardioids) have a
built-in bass boost when worked close. Many mics "pop" with sounds like
"p" and "b", and this bass boost makes it worse.
I've posted a photo of how I wear my CM500 -- the mic just above the
level of my nose AND to the left of my mouth. This does three things --
it minimizes pops and that bass boost, holds level more constant than if
the mic were closer, and, equally important, gives me room to drink
coffee and munch.
