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 ...
It may happen that, at the start of a scheduled CW rag chew, the frequency is in use, but only one side can hear that it is in use.
A cannot hear the existing QSO.
B can hear the existing QSO.
A ...
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 ...
Ok , so I know very very little about amateur radio, I've hear in some websdr frequencies morse code transmissions and I've got quite curious, what are they?
Who sends moresecode transmissions ...
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?
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 ...
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?...
Related to this question, but using humans, and in an actual QSO, not lab conditions:
Is there a record for QSO QRQ speed? And, if so, what is the record for the highest non-automated over-the-air ...
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 ...
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 ...
What sidetone frequency range (or VFO/BFO receiver offset) will allow one to copy CW when trying to learn to copy QRQ? (high-speed Morse code, 40 WPM and higher)
It seems like there will be very few ...
I understand high speed CW is used with meteor scatter, because the path only exists for a few seconds after the meteor passes.
I was wondering if automated high speed CW has an effective "speed ...
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?
I'm currently picking up signal from a beacon using RTL-SDR and decoding the Morse code on a computer using gMFSK program.
The beacon is sending message which decodes as "T DE YU1VHF LOC KN04OO".
I ...
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 ...
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 ...
