I fully agree with Jim, K9YC on the point of distortion. In fact there
are two signal paths in which distortion will affect ones results.
Certainly audio distortion on the TX side will affect the quality of

It is very common on VHF to switch to CW to call a guy who is transmitting on
SSB, most often after calling him on SSB doesn't get through. CW in SSB makes
it unnecessary to switch modes to do so.

I am using a StarTech.com USB3HDCAP USB 3.0 Video Capture Device to get the
P3 VGA signal into the WIN4K3 panadapter screen. I purchased the unit off
Amazon. Had to run the Star Tech video capture software to set the
connection up and then just ran WIN4K3 and set it up per instructions.
This is the way I use my K3. I use the P3-VGA to see the band
and tune with the knob (or K-Pod) following the display on the
VGA. I have not found the marker and knob on the P3 to be fun to use.

Using audio tones in LSB or USB mode for CW is risky business. Any
amount of over drive or excessive audio anywhere in the system,
computer, software, radio and such WILL cause problems. Same for hum or
