Gracias amigo Pete por esta clase magistral sobre las abreviaturas en cw.....

I found this presentation to be very well done. ..-.-... 73's from KK7ASP

fun and revealing video, thanks. It seems the cuts come from abbreviating the numbers using the dot or dash count of the letters: e.g 'a' has a single dot as in the number 1, 'u' has 2 dots as in 2, now it swaps over, 'w' as two dashes as in 3, v has 1 dash as in 4, etc, so 'g' has 2 dashes as in 7, 't' is all dashes as in 0. OK it's not unique but it does make some sense, a bit like abbreviating words by picking out the obvious letters: e.g. fb !

When sending Kenwood TS2000 i would send KWD TS2K. Some great tips there I have never heard AA or AB maybe they are used more in contests??

[@johncliff5417]

Just for a bit more confusion IMI AA or IMI AB or IMI FM ----- TO------. ( IMI=Brit Mill CW code for say again)

[@Brady.John87]

G is the 7th letter in the alphabet for the cut numbers section. :-)

Excellent, I enjoyed that. Thank you. G0OZY

[@jamesparlane9289]

I think Cockney Rhyming Slang is a better form of communication. The code falls to bits when people abbreviate.

[@garycutbill6457]

"6" looks like a lower case "B". "W" is "3" on it's side.

4 is Vier in German

The cut numbers I heard other commercial ship operators use were 1=A, 2=U, 3=V, 4=4 5=5, 6=6, 7=B, 8=B, 9=N & 0=T. do you have a source for your cut numbers?

[@briangreen7797]

Yes, the abbreviated number signals which you describe were to be found in the Post Office, "Handbook for Radio Operators", Appendix 1, International Morse Code Signals, Figures; which was published London: Her Majesty's Stationery Office, in 1975. [ISBN 0 11 880462 6] I don't know if this book is still available in an updated form, it's authority changed to the Home Office in 1977, then I believe it went to Lloyd's of London, and ended up in OFCOM.

@@briangreen7797 I still have mycopy of the handbook from when I was at sea. The cut numbers in that video I never ever heard in use by anyone and now I'm a Ham I've not heard the ones on the video used by other amateurs either.

@@098317 I attended Riversdale Technical College, Otterspool, Liverpool back in 1969-70. I was two or three weeks late on joining the Marine Radio Electronics Course, and although I could send ok with a straight key, I never caught up with the rest of the class in my receiving morse. I really enjoyed the course and thought I was doing well. I took my Dad to an open day, and I was shocked when I heard one of the tutors say to my Dad, I paraphrase, "The whole class is rubbish, they're not trying, they're wasting their money......" So, I left immediately! Years later I was informed by a friend who used to teach Marine Radio Electronics in another college, that they had to teach the students even though there were no jobs for them, and they weren't allowed to tell them that their jobs had been replaced by teleprinters! So my old morse tutor was doing me a favour, although it didn't seem like that to me at the time. I had a big row with my Dad left home and joined the Royal Navy as a Radio Mechanicain Apprentice. So some 50 years later I have decided to become a Radio Ham. I have got to find the syllabus from Ofcom, and do an online test apparently, which shouldn't take long. Referring back to the video, I was also surprised to find that they chose 'QSO' for the name of their code and not something else. It would not surprise me if the cut numbers were used by the SBS, SAS or the like, because it would not be obvious to everyone that numbers are being sent. Also it would shorten the time to send the message.

[@098317]

Your instructor wasn't exactly inspiring was he? Our Royal Navy instructors were excellent and taught us as you would expect to be taught when taught by professionals. I found CW absolutely no problem and enjoyed my several years in the Navy as a Radio Operator. The cut numbers he refers to I've not come across before - the ones I've heard & used internationally have been the ones I've mentioned and referred to. They are also listed in the Handbook For Radio operators, publishe d by the GPO. I doubt the cut numbers were used by either the SBS or SAS because there wouldn't take a decent monitoring service to recognise that they were abbreviations for numbers too. During the 70's & 80's and perhaps later the SBS & SAS had the ability to send their data at very high speed by satellite . - I'd guess they wouldn't be using CW to do this. I did briefly hear SBS trying to use CW when i was in Gibraltar in 1971. They were'nt particularily good. @@briangreen7797

Sorry---poor video. Five seconds in---very obvious. Again, sorry.

[@SnipCraftLeft]

Kinda unnecessary, just leave

[@joshwilson9393]

If you don’t like it, you don’t need to say anything. Just move on to another video. What good does it do to criticize when it’s not requested?
