[Elecraft] kxpd3 question

[Fred Jensen]

You are going to get a big bunch of replies, I see you already have 
quite a few, not all of which address your questions.  I'll try and do 
that, in 12 sections:

a.  Regular practice is necessary to send Morse code well, especially 
when learning.  The flavor of paddle, bug, or key doesn't matter.  Once 
it's in your head, it will be there for the rest of your life.  I was 
QRT in the mid-60's for 4 years while in SE Asia.  Once I came home and 
got back on the air, I was back to my normal in a month or so.

b.  The only difference between single-lever and dual-lever paddles 
[aside from the number of levers [:-) ] is that you can close both the 
dit and dah contacts at the same time on a dual-lever.  With an Iambic 
keyer [i.e. "squeezing], closing both will send di dah di dah di dah di 
..., or alternatively dah di dah di dah ..., depending on which side was 
closed first.  You can use a dual-lever paddle just like it was a 
single-lever paddle however -- I do and always have, and many other 
non-iambicized hams do too.

c.  I described Iambic-A above in (b).  Iambic-B allegedly arose from a 
logic misteak in a keyer chip.  Iambic-B will send a single element on 
it's own when the paddles are released.  If it is making a dit when 
released, the extra element will be a dah, and vice versa.  
Incidentally, all of today's keyers are self-completing ... they will 
always send correct length elements.  If you're sending a dah and 
release early, it will go ahead and complete the dah.

d.  It seems that whichever mode you learn on will become "your" mode.  
Once learned, most people have a hard time using the other mode, however 
I've never seen any empirical evidence that one mode has advantages over 
the other.  With either mode, there are about a half-dozen or so letters 
that you can complete with fewer finger movements using Iambic.  I've 
never seen the advantage, but some do and to each his own.

e.  Yes, the KXPD3 is a dual-lever paddle, however it can be operated as 
a single lever paddle as well.  The KX3 has an Iambic keyer that can be 
set either mode A or B [or Ultimatic, or bug mode I think]

f.  Yes, the KX3 and practically all radios on the market today have a 
KEY input.  It is a two-wire circuit, and when in CW mode, short the two 
wires and you transmit for as long as they are shorted.  This is also 
used with external keyers [WinKey, Microham, etc] where the external 
keyer forms the code elements from paddle input or ASCII characters from 
a computer.  The transmitter things it has a straight key in the KEY jack.

g.  Yes, for CWA, you will need to be able to send to yourself. You can 
put the KX3 into TEST mode.  It will act as if it's working normally, it 
just won't make any RF.

h.  While the KXPD3 is perfectly good for the KX3, it is very small.  
I'd recommend obtaining a larger paddle [single- or dual-lever, it 
doesn't matter] at a reasonable price while you're learning Morse.  The 
Bencher BY-1 is a very good choice, you can find them in several 
finishes on eBay, eHam, and at swap meets.  I have 2, one black base and 
one chrome.  Last time I noticed, they were in the $40-50 range.  The 
Hexkey [also by bencher] is a somewhat more expensive choice, Elecraft 
used to sell them, they may still.

i.  "Normally," paddles are configured with dahs on the finger(s) and 
dits on the thumb, however there is exactly zero magic in that, it's a 
holdover from the pre-keyer days with mechanical bugs.  You could get a 
"left-handed bug" but they were special-order and very pricey.    Nearly 
every keyer today allows you to "invert" that connection with a menu or 
control character.

j.  There is one advantage to configuring your paddle in the "normal" 
manner ... that's how most stations are configured and if you are a 
guest op, it will be right for you.

k.  A lot of left-handed hams learned to send [and subsequently paddle] 
right-handed because in the olden days, keeping a log was a Really Big 
Deal.  Send right, write left.  Strangely, almost no right-handers 
learned to paddle left.  I'm a lefty, I learned to send right, but when 
logs ceased to be an RBD, I put a second paddle on the left which I tend 
to use in casual QSO's.  You can do whatever works for you and you're 
guaranteed to be "right." Being able to paddle right-handed is an 
advantage if you ever are a guest op too.

l.  I don't know your age but a combination of injuries to my hands in 
my 20's, a genetic condition [poor choice of Dad], and an accumulation 
of birthdays took a toll on my ability to send at 35 even though I could 
copy it.  I finally purchased an N3ZN single-lever as a fairly expensive 
experiment.  Fortunately, I find the combination of single lever AND 
very precise engineering and design of the ZN paddle has brought my 
reliable sending speed up to 25 or a little more.

I notice that you've gotten several replies that assert [I'm 
paraphrasing]: "You should never transmit Morse until you've practiced 
off-line for at least half your life."  Jerry, that is the same "advice" 
you can find in a feedlot full of male bovines. It's in the same 
category as, "You should never send on a bug [nowadays that includes 
'keyer'] until you can send War and Peace in its entirety with no 
mistakes on a straight key."  If your CW isn't perfect, so be it.  The 
best way to become fluent in Morse code is to get on the air and use 
it.  If someone thinks your fist stinks, he doesn't have to answer your 
call.  Getting on the air is also the best way to discover all the 
things you can do with Morse and why it appeals to so many.

[Full disclosure:  I'm a member of CWOps]:  Congratulations on starting 
CWA.  That CWOps program has many graduates, some learning from scratch, 
some seeking to improve their ability in the mode.  Their method works, 
the Advisors are extremely good at applying it, and I look forward to a 
QSO with you in the near future.
