Hi Phill and other resolute fanatics.
Fascinating topic here.
I am not a Radio Ham but was Merchant Navy Radio Officer in my youth and can confirm the meaning of CW.
The true definition is “ A continuous wave or continuous waveform which is an electromagnetic wave of constant amplitude and frequency.This is normally in sine wave form which for mathematical description is of an infinite duration, ie early radio transmissions”
All good stuff and the birth of early transitions.
The job I trained for all those years ago (Radio Officer)is now with the demise of Morse Code as an official language dead.
We also used to use Q codes as abbreviations to save time sending Morse.
Memory is a little grey now but some examples of the Q codes were.
QRA...What ship or station are you.
QRB...What is your distance.
QRC...What is your true bearing.
Etc etc.
If I remember correctly there were 43 Q Codes for different nautical terms.
Just a little useless info for you all,but if we could combine all the skills and knowledge we old timers have from our previous lives the world would be a better place.
As I say to my Grandchildren,Daddy knows most things,but Grandad knows everything.
On that note I will say,
QRT.
Keep up the good work on a great site.

Sorry for getting it wrong, I'll have to get my friendly Ham radio neighbour to give me some pointers.
Cheers Colin. 👍

Hi Colin, no problem re abbreviated text.

Just to clariy, for those who are not aware, these abbreviations are amateur radio terms which are used when decoding CW.
CW being an abbreviation itself for "continuous wave" as used in morse code.

Morse code was introduced around 1830s and by the 1930s (long before mobile phones / texting etc.) , CW was the preferred form of communication for aviators and seamen, and it was vital during the Second World War.

mni tnx de g0wsp (70 turns on the coil) -.- 👍

If model yachts are your thing and you have even the slightest interest in Arduino then this is a great resource
