CW to PSK encoding

[Al Van Buren]

Have any of you noticed that when using a cw paddle to send PSK from the K3 a
few of the translations are not correct.  For example, when sending 1234567890
from the paddle, the K3 transmits 123 E g w C O9 0.  If I put a space between
all the numbers, then I get a correct translation.  That wouldn't be too bad,
except that when ever I send my call k7ca, the K3 sends  k Cca.  Again, if I
leave a spact between the 7 and c then it comes out ok as k7 ca. I am taking
the K3 to Chile for a couple of months this winter and thought it might be nice
to make a few digital qsos without a computer.  73, Al K7CA

No, sorry. Even with my limited paddle operating skills I can send your call OK, and the numbers, as received via audio using the K3 monitor and another computer .

What firmware version are you using?

The release notes for version 2.57 include:

PSK31 (PSK D MODE) TRANSMIT IMPROVEMENTS: Eliminated erroneous
characters during CW-to-PSK31 transmit when using the keyer paddle.
Also greatly improved PSK31 transmit speed by removing all extraneous
"zeros" from the data stream.

I hadn't noticed any erroneous characters myself, just errors of my
own making since the decoder is strict about the timing of morse
elements. The feature has been quite useful for casual contacts when I
don't have the laptop at home or don't want to bother bringing it into
the shack and setting it up for psk31.
