I'll have to get some software to help me get efficient again. I've held my radio amateur licence since 1960, but have never been very good at morse. However, now I've got a bit more time on my hands, I am trying to brush up my skill and, in my spare moments, have been doing some 'SWLing' on the morse parts of the amateur bands. I recently-bought Eton E5 receiver is handy for use in places like the toilet, where listening to morse makes a change from reading a book or the daily paper. I can confirm that, although many countries no longer require morse in order to get the licence, there certainly is a heck of a lot of morse still used by radio amateurs. It's certainly NOT a dying art. For beginners, the main problem is finding transmissions which are slow enough to be understood. Fortunately, there are dozens of excellent freeware computer programs which generate morse for you to practise with, and allow you work up your speed. There are also a lot of morse decoder programs which take your receiver audio output and display it as text. Even if you are getting quite good at morse, and are pretty good at decoding it 'in your head', the display of the text 'subtitles' provides an instant indication of how you are doing. Some programs indicate the speed of the received morse, and I was surprised that I now seem to be able to copy quite a lot at up to 20wpm. -- Ian |

W1AW sends codes practice lessons on week days..
Several times a day and many bands.. also code bulletins.. check www.arrl.org for the frequencies and times .. or check QST -- Thanks & 73 Hank WD5JFR wrote in message ...

I don't think there's a radio made that doesn't call it "CW". The VBR binary system invented by S. F. B. Morse for electric clicker DC wire communications might resemble CW at first glance, but modern CW is quite different. |

Does this mean I can't receive CW? Just what HAVE I been listening to while sitting on the toilet? Can you describe the sounds for us? CW is the "Mode" of Transmission {Signal} * CW = Continuous Wave Morse Code is the "Method" of Transmission {Information} * Structured Organized Bits of Continuous Wave . Oh dear. My old Trio TS520s DOES say CW. Pity. I was hoping to use it for SSB and morse. What AM I going to do? -- Ian |

I don't even want to think about it. :-) It says SSB because it sounds better than BFO. BFO is part of the radio, SSB is a mode. Oh dear. My old Trio TS520s DOES say CW. Pity. I was hoping to use it for SSB and morse. What AM I going to do? My 520se had USB/LSB and CW. In any case it does not say Morse, because that would be like saying French or Japanese for the voice modes. The radio does not differentiate between codes used for CW transmission. It just makes a beeping noise when it receives a carrier. If it receives International Morse Code, or 1 for a, 2 for b, 3 for c, etc code, it still does exactly the same thing. I forgot to mention that, in the LSB or USB positions, my TS520s also seems to work on SSTV (and morse). It just goes to show that you shouldn't believe what is written on the tin/packet. [And I haven't yet got around to using it on packet.] -- Ian |

Morse for electric clicker DC wire communications might resemble CW at first glance, but modern CW is quite different. What About ? Listening to Morse Code with a 'portable' AM/FM Shortwave Radio using the SSB Feature ? - Well, my Etón E5 certainly doesn't say 'CW'. - It says 'SSB'. For 'portable' AM/FM Shortwave Radios that have SSB as a listening feature : Most likely the SSB Setting switches-in a Narrower Filter say 2.8 kHz versus the AM Filter of 5~6 kHz. So you can hear the CW Morse Code Signal more distinctly and clearer in the SSB Mode. But -if- you have a tightly packed Band with many CW Transmissions crammed into your 2.8 kHz SSB Filter's Bandwidth you will be hearing two, three or more CW Transmission all at once. That is why Shortwave (HF) Radio Listeners who like to listen-in-on Amateur {Ham} Radio Operators CW Transmissions usually get a Communications Receiver with CW Filter or Spots for Extra/Optional CW Filters for Listening to CW Transmissions * Some common CW Filter Sizes [kHz] are : 500 Hz . . . 375 Hz . . . 250 Hz which are much Narrower than the 2.8 kHz of most portable AM/FM Shortwave Radios. - Does this mean I can't receive CW? No. -but- You may not be able to narrow-in on a specific CW signal in a crowded band with a Radio-Receiver that has Narrower CW Filters like 500 Hz. - Just what HAVE I been listening to while sitting on the toilet? Noise coming out of the Radio ;-} - - CW is the "Mode" of Transmission {Signal} - - * CW = Continuous Wave http://en.wikipedia.org/wiki/Continuous_Wave - - Morse Code is the "Method" of Transmission {Information} - - * Structured Organized Bits of Continuous Wave http://en.wikipedia.org/wiki/Morse_Code Oh dear.

SSTV is essentially sideband (requiring the BFO), in that the video SSTV signal is plugged into the mic jack...and naturally, CW (morse) requires use of the BFO --so what you describe is not surprising. |
