[Elecraft] K3 V4.61 CW decode broken?

[Brian Alsop]

Was checking out RTTY decode which worked fine.  Decided to look at CW 
decode.

Here are my observations.

Not working well here or op here inept at using it.

My perception is that it did much better in older versions.  However, I 
didn't use it much then.

ZL9HM was 599 @35 wpm this AM.  WPM check always showing between 48 and 
82 wpm. Decode with WPM check off was bunch of E's and T's.  Not due to 
noise.

Using 400 Hz filter in CW mode.  Tried auto, both choices for speed, 
auto, different thresholds.  Closest to working is auto.

Similar problem with C6AKQ at 32 wpm when decoding some characters right.

Both stations generating machine generated CW.

I'm also thinking that these stations are using "contest" spacing of 
characters which may be confounding. In WINKEY and N1MM the word spacing 
for contest spacing is 6 dits/wordspace instead of normal 7.

Admittedly these are really short exchanges and the time to lock on is 
really short.  However, my guess is that these are the exact conditions 
some guys are using the decoder for.

A longer rag chewing K9 at 28wpm did decode OK but was not spectacular. 
Although his signal was strong, characters were dropped.  He seemed to 
be using normal spaced CW.

I'm wondering is "contest spacing" is confounding for the decoder.
