P3 CW Decoding doesn't match K3

[Elecraft mailing list]

While copying the ARRL 20M CW broadcast I noticed that the decoding on the K3 is quite accurate as long as the signal does not fade. But while the K3 is decoding very well, the data display of cw text on the bottom of the SVGA display  is no whereas close to the accuracy of the K3. Anyone else encountered this? I  don't see any applicable options in the SVGA menu on the P3 menu.

By any chance, do you have text display enabled on P3 Utility?  The text
display on the P3/SVGA and P3 Utility are mutually exclusive - only one
should be turned on at the same time.

The K3 does the heavy listing while decoding CW and it and the P3 should be the same.  What you can't do is use the K3 Utility and the P3 to display code simultaneously.

I believe the P3SVGA only reproduces whatever characters are on the VFO B display. The P3SVGA does not separately decode the CW. If you are not getting faithful copy of VFO B on the K3 to the P3, something is amiss in the station setup.

Try disconnecting anything else from the P3/K3 combo that is connected to any of the data ports on the K3 or P3 and see if that clears it up.

You can easily test the transfer by recording a data mode message at the K3 and playing it back with the K3 in TEST mode so you aren't transmitting. You should have perfect copy on the P3SVGA monitor.

Fred- I am not using the K3 Utility at all, just the P3.

Hi Paul,

I read your post that you do not have the K3 Utility running, but 1) is your P3 hooked up to your computer and 2) is there any software running on your computer that would be reading the text such as a terminal program, or the P3 Utility?

The P3/SVGA simply gets a copy of the K3's decoded text and displays it on the screen.  There is no separate decoding being done on the SVGA card.  Therefore the problem is likely in the serial port between the K3 and P3, or some other program is fighting for the data.  Check the serial cable between the K3 and P3.  If you're still having trouble, email me directly at Elecraft.  My email is pauls at you know where dot com.

73,

Paul
