[Elecraft] k3:TX Monitor-some odd sound -beta?

Yes, I get this artefact. It's been evident ever since I got my K3. You will
notice that it is made worse by excessive mic gain or compression.

I hope it is an artifact in the monitor circuit, and not on the transmitted
signal !

Hi

Just noticed this when playing around with the K3's monitor.

With the Gate off
EQ flat
MH2 hand MIC
TX test mode
Band 7mhz

While whistling there is a odd artifact. If I whistle I get a sound that
sounds  like a oscillator pulling in a receiver. I dont get any odd sounds
with normal voice testing

.With a continuous whistle I get this artifact that  is a mirror of the
whistle, however it seems to shift frequency or pull the louder you
whistle.It might be a IMD  product? I have never noticed this before in the
K3's monitor. I will also check the clubs K3's and report back.

Anyone else get this?

John
