Morse Code and "CW," you say?
brief history and overview of Morse Code - And many interesting
resources on telegraphy: Communication Across the Nation - The
History of the Telegraph Brought
to you by Samantha, a student in Ms. Smith's 10th grade Social
at Brighter Futures Charter School in California. -
Thanks Samantha! See my
Labs SW+40 QRP CW Kit...
This is a
very well designed kit for transmitting and receiving Morse Code
Benson, K1SWL, at Small
Wonder Labs (discontinued) and was only
No longer sold by Dave, this rig has very good performance and many of
the features found
on larger rigs. Intermediate
knowledge of electronics and kit building are required, but well worth
the effort to build one yourself.
how I built this nifty CW filter: (Updates Soon)
Using the formulas in the ARRL Extra manual and some junk parts, this
60hz wide CW audio filter fits in a small mint tin, is powered from a
9v battery and will bring weak and overrun CW QSO's out of the mud... Schematics
and instructions inside...
Learn the code! - Don't be turned off by
CW, it will grow on you.

- I was able to perfect my knowledge of each Morse Code character, then
being able to practice and increase my copy speed.
I discovered that I copy code at different speeds differently. For me
to copy a QSO I can handle 15wpm (head copy) effective,
but I can hear characters over and over and copy them individually in
the 50's (wpm).
To learn code, you must do it by
recognizing the "sound" ONLY,
hear the individual characters as fast as 20 to 25 wpm equivalent but
space the characters apart so that the effective speed is a slow as you
need it (5 to 15).
Learn each letter one by one additionally and proceed only when you
know those letters.
This will yield successful results!
This is my vintage WWII Army
Signal Corps straight keyer. It was inherited from my XYL's silent key
After a can of Brasso it cleaned up nicely. You can still find these on
eBay and at army surplus stores for not much money.
of mine and fellow kit builder donated this QRP rig board to me.
a KD1JV "Melt Solder" DC30 series QRP CW Rig available from Hendrix
The current version
of this kit is called the DCxx, it's only $30 and has been improved
(See here:) It
was my friend's practice board used to help him learn to solder back
when he first got into kit building. It
wasn't in too bad of shape. It just needed three printed circuit traces
to be repaired, along with a bunch of cold contacts and oddly enough,
an IC socket.
transceiver is a single frequency CW rig using "direct conversion"
power input is a full 1
watt with a supply of 13.8 volts.
It's 0.7 watts at 12.0 volts. That makes this rig a "QRPp" transceiver. It's
actually a pretty good improvement over my own QRPp attempt (see above
link). It boasts good sensitivity and BC/SWBC rejection, along with a
600 Hz Transmit/Receive offset shift. Shown
here, the board was mounted into an AltoidsŪ metal mint tin with
holes drilled. Space
is tight, so the RF antenna BNC connector had to be hack-sawed
down to fit.
and adjustments were made to the board.
A piece of
plastic was used as an electrical insulator, and basic wiring
connections were made. My
goal was not to spend a lot of time and resources to get this one
running, but to show others how easy it is to mount a QRP rig like this
inside of a simple enclosure.

costing a grand, but, It is very well designed and implemented, though. By
it's nature, it's intended to be a sweet and simple little kit for
anyone to enjoy. A great weekend project even for beginning kit

End of Transmission.
- when you are sending it back to the other station. Also used at the
end when answering a CQ.
End of Transmission.
- when you are at the final end of a last transmission of a QSO.
Go Ahead... Over.
Used when turning it over to another station. Used also after sending
NOT to be used after just answering a CQ because the other station has
not verified contact with you.

Ending last QSO and turning off station. No one else to come back or

Q-signals are three letter combinations used to
represent common phrases or sentences for CW operation. They may be
used as a question with a question mark (?) or statement without the
question mark. For example, "QRZ?" is used to ask for the calling
station(s) to identify again. "Please (pse) QRS" is used as a request
to send the code at a slower speed. "The QTH is" is used to indicate
this station's location.
Although originally used for CW, many Q-signals
have become acceptable for phone operation.
