Clipping first element of CW - K3/KPA-1500

[G4BVY]

Hi Pete
I had this problem as well - it is a "feature".
It occurs if the rising edge of the keying waveform happens at the same time as the PTT line.  The ONLY way around this is to delay the keying waveform slightly so it occurs after the PTT.  If you are using a WinKey, then set the "lead-in" delay.  There is also a feature in N1MM to achieve the same result.

Subject: [Elecraft] Clipping first element of CW - K3/KPA-1500

Running into what I'm sure is a simple matter of menu settings, but...
My K3 is set for PTT with a "normal" TX delay of 008 (I presume 8 ms.), driving a KPA-1500.  I am getting persistent reports of clipping one dash worth at the beginning of each transmission, so my casll becomes "E4ZR", for example.  I've been through both manuals, and aside from setting a higher TX Delay, I don't know what I can do to clean this up.

so what am I missing?
