Forward initial radio

[Music] thank you [Music] hello and welcome once again to the Waterson Stanton video channel this is a really a question that perhaps you can answer and have your views on if you are a CW Enthusiast or indeed you operate CW when you send a report out you send an rst reporter out readability signal strength and tone 599 is a regular report particularly during contests and one thing we all understand why we send that report out but because gives the guy at the other end an indication of how strong he is but I really question the last digit the last digit which stands for tone do we really need that these days you know I can't remember the last time I heard anything other than a nine as the third digit in the rst report and I certainly can't remember giving anybody less than nine um might be in the early days I might have done and actually there was another um there was a suffix to that which we occasionally used and that was C so it might be five nine eight C all right meant there was a slight uh slightly roughness to the tone and C stood for chirp well again I can't recall ever given a report like that certainly not in recent years or recent decades I suppose and I certainly can't recall ever receiving that and so really and truly I suppose we it's right to question do we really need that last digit anymore because most transmissions in there well I say most almost all transmissions are T9 occasionally you hear a rough one but generally speaking they're all T9 and certainly it becomes a meaningless indicator in contest and I think the T9 or the T tone goes back to the early days of radio I'll put up on the side of the screen here now the T code as you can see um it goes from a very rough tone to a perfect tone in fact I should explain this obviously is the American interpretation because it mentions a 60 uh cycle as it was then 60 hertz um tone and of course in the UK we're on a 50 hertz main so but it's it gives you the general idea and I should mention actually apart from the chirp suffix there was also the K suffix which stood for key clicks and I guess if you really had a pretty awful signal it would be five nine two c k and that was pretty awful signal um and as I say this really goes back to the early days when all transmissions were CW or Morse code and it was obviously adapted later on when phone was introduced to am and subsequently SSB and the early transmitters were not very stable and they did have chirp and key clicks it was inevitable and the notes were rough it was the it was it was difficult in...
