This brings to the forefront, the question of what is the bandwidth

99 wpm??

Good question.

While the signaling rate of a CW signal does have an affect on  
bandwidth, the majority of the wideband products come from the rapid  
rise and fall times of the signal envelope. (that's why key clicks  
are heard so far away from the operating frequency) Don't expect a 99  
wpm signal to be much wider than 35 wpm.


That said, no one can copy a 99 wpm CW signal. The top QRQ guys are  
around 60 wpm.
  With the regulation by bandwidth, does this now put a speed limit  
on cw?


Potentially, but that limit is so high as to be practically no limit.

Keyboards - definitely! It's the only way to consistently generate  
high-speed CW.


Readers - definitely NOT. Most QRQ ops copy in their heads. They  
wouldn't lower themselves to use a reader.


Back in the late 70's, when I was a Novice, and later a General, I  
was involved in the WV Novice Net. A couple of the net control guys  
were blind hams. They would call the net at 5 wpm, go through the  
traffic, close it, and then call each other on the 'net frequency --  
at 40+ wpm! They both had CW keyboards (which were pretty new back  
then), and would converse quite a bit back and forth at these speeds.



A few hams out there can skip along at 30-40 WPM but they are in the
minority by far.  Contesters don't count as they are locked into  
a set

format and not much information is actually exchanged except for
the required data.


Most of the really, really good contesters I know can also copy  
conversationally QRQ CW.


Me? I can do almost 30 wpm in a contest, but I'm back down below 24  
for conversational CW.



Really good high speed telegraphers are rather
scarce.  (I'm speaking of those using straight keys or bugs, or
sideswiper keys).


That's pretty much a dead art.

CW Speed (RE: [Elecraft] QSK Redux)

2006-05-09 Thread Darwin, Keith

-Original Message-
Ouch,
 
25 wpm is cw with training wheels.  In the real world people don't send
that slow.  Bummer.

Ouch indeed :-).  My fastest reliable speed ever is about 25 wpm.  It's
almost embarrassing to say I've been 90% CW for 15 yrs and my speed has
yet to get much over 20.  I guess I'm just not serious enough about it.

But, I have a lot of fun with the straight key (SKCC) working stations
at 15 wpm +/-.  We can get beyond RST/OP/QTH and actually talk to each
other.
