Are there standard ways to connect a hand key (straight or paddle) to a contemporary computing device (PC laptop with no parallel port, Mac, Android, iOS device, etc.) for developing or improving ones ...
My 5-year old son loves sending out an SOS signal using a toy Morse code generator (wired, don't worry about false alarms for real authorities).
He has learned to send the SOS signal and was asking ...
At first glance Morse code looks like a digital mode - there are dits and dahs, two values which contain the information of the transmission. Alternatively, at any point in time there either is a ...
I am studying for my FCC General Class license, and question/answer G4A02 reads as follows:
Q: What is one advantage of selecting the opposite or "reverse" ...
I need some recordings of CW / Morse code for use in a project. Most of what I find is either nonsense (it just exists for the 'sound of CW', but doesn't contain a message) or is generated by a ...
I remember being surprised to learn that a CW signal has a bandwidth (albeit small), but when I thought it over, it made sense. Essentially, we are modulating the carrier with a low frequency square ...
5 wpm is easy to learn and better than nothing in emergency.
Speed Morse Coding is fine for "sport competition"
I am trying to find out which is the typical speed for what I call "conversation" and ...
The ITU's International Morse Code recommendation ITU-R M.1677-1 specifies a "Full stop (period)" as ".−.−.−", however it falls short of specifying a decimal point. Even the examples, though they ...
What is the RF bandwidth of a typical CW signal? How is the signal bandwidth affected by WPM and/or transmitter rise-time?
What is the narrowest bandwidth that can still be copied by a human? Or ...

My uncle, who was a Merchant Marine in WWII used to tell me this. He was a ham, and said it would develop my fist musically.
I was a small child at the time, and through his ...
When learning, teaching oneself, or training a class in Morse Code sending using a hand key, how can acceptable quality be scored (other than the letters being correct terms of dot-dash sequence)? ...
I ended up with an old straight key that has a curious feature: below the main arm that you would tap on, there's an extra metal flange that can sort of loosely pinch an extra sliding lever underneath,...
Let's say I get my little 2 meter FM handheld out and make a little sine-wave generator with which I pulse a morse code and if I connect it to headphones a speaker, I hear the dits and dahs of a nice ...
In Morse code, hams use "hi" to indicate a laugh, and "es" to mean "and".
Where did these abbreviations come from? Both being all dots, they are short and easy to send and easy to recognize, but why ...
I want to eventually use a CW paddle and built in keyer in my Yaesu FT-890. What are the merits of each style. Single or Dual Paddle. Does it make any difference if I start with say a dual paddle then ...
I solely learned to copy cw via a computer program using the Koch - method
(http://f6dqm.free.fr/soft/cwplayer/en/cwplayer.htm)
I never learned how to send and if it is no big disadvantage, I would ...
To receive the amateur radio license Klasse A (HAREC) in Germany it is since 2005 not required anymore to pass a CW exam, due to a corresponding change in the Radio Regulations. However, the exam is ...
In the U.S., regulations permit CW operations throughout the amateur bands. That makes the phone section of a band look tempting when the CW/digital part of the band is busy with a contest. I wonder ...
How is the signal-to-noise ratio for received CW and QRSS CW (and/or other ultra narrow-band DSP digital modes) typically computed? e.g. What noise bandwidth should be used to measure the spectrum ...
There are many anecdotes of hams learning Morse Code at e.g. 5wpm and then "hitting a wall" trying to gradually speed up to 15wpm.
David G. Finley, N1IRZ claims the reason is this:
Morse at 5 wpm ...
As I recall, it used to be in the U.S. that the ability to read and send Morse code over CW was a requirement for an amateur license (and was tested, I believe). Is that still true in the U.S.? If ...
Does the official International Morse code include alphabetic characters other than the 26 letters of the English alphabet? If so, what are the most common other alphabets or characters that one ...
Back when Morse code proficiency was required for certain radio licenses, what audio frequency was used by the exam tapes, equipment or examiner that generated the Morse code audio? Was there a ...
I'm new to CW and one thing I couldn't figure out is when I supposed to send "E E". Let's say I'm calling CQ and somebody answers me. The QSO is almost over. Should it be ended like this:
...
Back in the 1960s during my Novice days I operated on the 40-meter band only with 4 different quartz crystals that determined my transmitting frequency with my Eico 720 CW transmitter. I had heard ...
Given that it is no longer a license requirement, are there any current statistics available on what percentage of licensed amateur radio operators still learn Morse Code to some degree of proficiency?...
So I'm developing my own SDR software from scratch (I like to "own" the code). The channel between the RF-to-USB hardware and the software is 192kHz sample-rate IQ audio samples. The degrees of ...
Sometimes when operating CW I want to send numbers that are negative. In particular when operating outdoors during the winter and someone asks the temperature, I would like to come back in CW with -...
I am wondering how hams transmit coordinates in Morse code. Considering that coordinates can be represented in many different formats (such as DD, DDM, DMS, WGS84, etc.) and that an error in the ...
I was just thinking about making a QRP transceiver, but are they only used for CW (Morse code) communication?
If it is so, can I modify a QRP for two way audio communication?
When using coherent CW, how is the receiver frequency and/or Morse Code dot clock synchronized to the transmission precisely enough to allow for synchronous decoding?
The ARRL hosts many contests throughout the year, and maintains a leaderboard of sorts to encourage competition.
Is it possible to rank on any of the leaderboards without knowing or using morse code?
What are "key clicks"? How much does the rise time or bandwidth of a CW signal need to be limited to prevent other QSOs on adjacent frequencies from being annoyed by "key clicks"? Is there a legal ...
I just got an old brass key at a hamfest, and it appears to be in pretty good mechanical condition, aside from some dirt and dust. Taking it apart, the key (apologies for not knowing the exact ...
When using Morse Code as an accessibility/disability communication or input method, are there any non-alphanumeric dot-dash sequences that are more common or more suitable for meta-commands, such as “...
When I got my license about 50 years ago, I believe the only punctuation marks on the test were the period, comma, question mark, and slash mark.
Once on the air, I heard and used the usual prosigns, ...
What is the history on the term “lid” when referring to a telegrapher’s capability? How did it originate and what is the significance if any of each letter?
I've heard lots of contest exchanges, and the signal report almost always seems to be 59 for phone or 599 for Morse, even when the operator giving the report has to request information to be repeated ...
On the UK Band Plan there are frequencies stating “QRS (slow telegraphy) Centre of Activity”. For example, 14,055 kHz on 20m and 3,555 kHz on 80m.
What is considered slow? (<15 wpm?)
How close ...
I tried making a CQ on 20 m, 14.060 MHz (the QRP CQ frequency) and parallel to that I had a WebSDR on my computer just to keep an eye on the band. I saw someone responding on the WebSDR, which is ...
I tried to use both:
Cwget
CW decoder
But neither one worked. Can you recommend a tool or an alternative approach to decode a Morse message saved as an Mp3 file?
What are some characteristics, when sending CW, of a "bad fist"? How bad can it get, typically, and still manage to communicate the message text sent to a human operator on the receiving end?
Contra-...
According to this question MCW (modulated continuous wave) is allowed on large portions of the VHF bands in the U.S.
Is using MCW suitable for passing small amounts of digital data between 2 PCs or ...
I would like to practice in CW on 2m/70cm bands when and if there will be a tropospheric or sporadic-E propagation. However I don't have mush space for the antenna. There is a possibility to install 3+...
If one passed the Extra written test in the late '90s at an ARRL test center but did not get the 20wpm endorsement, yet is an Advanced operator, would they now be upgraded to Extra class or do they ...
