[Elecraft] K3 CW speed request

2008-07-03 Thread charles
Is it possible to have a speed step of .5 in between the present CW speed 
settings of whole numbers?

I am particularly looking for a CW speed of 21.5 wpm just now.

A linear speed setting instead of the step change would be even better :-)

Charles, I doubt that the tolerance of the K3 displayed speed is better 
than +/- 0.5wpm, so you may find that 21 or 22wpm could be just the 
speed you are looking for.  Have you measured it accurately?  Your 
findings would be of interest here.

I measured the sidetone dah lengths at the speaker: 

A 22wpm dah is 0.207 sec; a 21wpm dah is 0.219 sec. Not sure about the
conversion to wpm but I think this comes out to 24 wpm and 22.8 wpm
respectively; could be wrong.

Those dashes sound a little long.  The formula normally used to calculate 
lengths of  elements is

dot length (msec) equals 1200 divided by wpm.
 Thus, at 22 wpm, the dot length should be 54.5 msec.  Dashes are normally 
three times as long, i.e., 163.5 msec.

Re: [Elecraft] K3 CW speed request

Dahs are actually twice the length of dits, I think. Or technically,
the dah period is twice the dit period (i.e., a dah sound plus its
space is equal to two dit sounds and their spaces).

I measured the dahs instead of dits because I don't have a keyer; just
pluged my mono straight key plug into the paddle jack and it gives
dahs. 

I measured the period by averaging over five dah periods with the K3
readout set at 22 wpm and 21 wpm, giving periods of  0.207s and
0.219s, as mentioned. I measured the sidetone at the headphone jack
using audio waveform software.

The settings on the speed control knob are a step change.
I am asking if the size of the step change can be reduced from 1 wpm to .5 wpm 
(nominal).
Maybe I should be requesting that the character speed setting should be halved 
and indicated in .5 steps because the speed control knob actually controls 
the character speed.
The actual overall wpm is set by the sender depending on the timing of the gap 
between each character and each word.
I hope that I have now clarified just what I am requesting :-)

The Logikeyer changes the character speed on a linear scale which gives the 
operator greater control and flexibility.

What's confusing is why anyone would need 0.5 wpm resolution.  If 21.5
wpm is the target, why isn't 21 or 22 wpm good enough?  I suspect there
is a reason but I can't guess what it is.

If you need true 0.5 wpm resolution and an accurate 21.5 rate, maybe it
is time for an external keyer.

Ok, using your formula, and allowing for my measurement of dah periods
(not just dah sound portion of cycle), substituting equivalent dit
sound time (at assumed 3:1 ratio), I get the following conversions:

22 wpm K3 readout  
measured 0.207 dah period 
51.8 msec dit sound equivalent at 3:1 ratio
23.2 wpm calculated by the 1200 formula

21 wpm K3 readout

54.8 msec dit sound equivalent at 3:1 ratio
21.9 wpm calculated by the 1200 formula

Re: [Elecraft] K3 CW speed request

2008-07-03 Thread Andrew Faber

Drew,
 I don't think that is correct.  Normal CW has a dash that is three times 
as long as a dot. If you have dashes as short as twice as long as dots, the 
code sounds very strange.  The ratio, i.e., three to one, is purely of the 
length of the character.  Normal spacing between dots and dashes is one dot 
length, independent of the dot to dash ratio.  If the transmitted code 
sounds OK, and the dashes are truly as long as you say, then the speed 
control is mis-calibrated.
 I note that the K3 has a menu entry for what they call CW Weight, defined 
as the dot to space ratio (although often CW weight is used to mean the dot 
to dash ratio). Not sure if there is a way on the internal keyer to vary the 
dot to dash ratio. Most outboard keyers allow you to play with the dot to 
dash ratio, and some people like to vary it a bit from three to one.

 OK, now I understand: your times are for a dash plus one space.  So, in 
effect a dot would be one quarter of that length at normal weighting. 
Sounds like the calibration may be within the error of measurement.

What everyone really wants to know, Charles, is *why* this is important. 
It would cause speed changes to be slower, and special care on the part 
of the programmer to assure precise timing. Timing issues in a radio 
like the K3 are complicated, because of the asynchronous events which 
also have to be handled.


In addition to the inaccuracy of the keyer, the operator's spacing is 
highly variable (even if the keyer supports autospacing, which the K3's 
does not).


In my experience a resolution of 1 wpm is quite adequate. I've been a CW 
operator for 51 years, although I'm not sure how relevant this is.


So the question is, what's magic about 21.5 wpm?

Charles,

I see nothing wrong with your question and have no reason to object to it's
implementation.

Now, I would like to pose a question to the group:

Do you actually use your K3's or do you test them all the time?

I see many posts under the original that are nothing but OT discussions about
character spacing, length ratios of dits and dahs, etc.  These posts don't
answering Charles' question and many times they end up going on forever, like
this one will.

Please, let's stop changing the subject of posts by turning them into OT
technical discussions and use another forum to discuss OT technical subjects
that don't relate to the poster's question or statement.

Best regards to all,

Tom, N5GE

Hi Guys,

Unfortunately it is not practical for us to do 0.5 WPM increments in the 
firmware for a number of internal reasons.


So let's end this thread for now.

Also, please remember to restrain posting when you see more than 10

Re: [Elecraft] K3 CW speed request

 What everyone really wants to know, Charles, is *why* this is important.
 It would cause speed changes to be slower, and special care on the part
 of the programmer to assure precise timing. Timing issues in a radio
 like the K3 are complicated, because of the asynchronous events which
 also have to be handled.

 In addition to the inaccuracy of the keyer, the operator's spacing is
 highly variable (even if the keyer supports autospacing, which the K3's
 does not).

 In my experience a resolution of 1 wpm is quite adequate. I've been a CW
 operator for 51 years, although I'm not sure how relevant this is.

 So the question is, what's magic about 21.5 wpm?

Thanks for the reply Vic.
Nearly all my operating is on CW rag chew. The microphone is only plugged in 
for the Radio Club SSB net. I have ten year's experience of CW operation and 
I would say that I am still learning.
I like to send at a speed that is close to the other guy's speed.
I like to send clearly with correct spacing and without too many mistakes so 
that the other guy can copy well.
At my present stage of learning CW I can comfortably send at 21 wpm on the K3 
speed control. I am referring to a rag chew that can last up to 30/45 
minutes. I do not know what overall speed I am sending at and it is not 
necessarily relavent to this discusion.  There are days when I can send well 
at 22 wpm on the K3 speed control and meet the above requirements to ensure 
that I am sending clearly and in a way that the other guy can copy well.
However, there are days when the K3 speed control of 22 wpm is too fast and 
days when the K3 speed control of 21 wpm is too slow.  On those days I would 
like to be be able to set the K3 speed control to 21.5 wpm. There is 
nothing magic about this :-)  perhaps one day I shall find the need for a 
K3 speed control of 22.5 wpm :-)
Perhaps the reason why I have this problem with the K3 speed control is 
because until I started using the K3 internal keyer I have always used the 
Logikeyer from Bob Locher.

I hope that I have described my situation adequately and that I have now 
clearly explained the reason for my request for a finer resolution on the K3 
keyer speed control knob.

 Hi Guys,

 Unfortunately it is not practical for us to do 0.5 WPM increments in the

Thank you Eric - That's all I wanted to know :-)

Is it possible to have a speed step of .5 in between the 
present CW speed

settings of whole numbers?

I am particularly looking for a CW speed of 21.5 wpm just 
now.


A linear speed setting instead of the step change would be 
even better :-)
