Morse Code / Learn Morse Code in 20 Lessons (Koch Method)
« Last post by Sparks on September 20, 2017, 12:53:07 AM »
You want to learn Samuel F. B. Morse's (shown above) most famous code. The South Canadian Amateur Radio Society (SCARS) wants to help. Mark Kleine N5HZR developed this series of web pages to help you learn the 40 characters of the International Morse Code in about 20 lessons. Additionally, you can continue to practice hearing your code for another 20 lessons. In the first lesson we introduce two characters, the letters K and M. Think of this as if you're learning the sounds 'momma' and 'dada', as an infant. You'll listen to these characters, learning to hear, and differentiate their two sounds. Then, you'll come back each, and every day (or two) and listen to 2 new characters in 5 lessons of 5 minutes each. You don't have to listen to all 5 at one time. You can listen to a couple the 5 minute sessions at breakfast, one at lunch, and the last two in the evening. Make each lesson enjoyable, and you'll have a better experience.

Each day you'll build on the characters you already know. During the first week, you may feel frustrated or you may have trouble hearing each individual character. However, by day 5 or so, you will start to notice that the characters are 'slowing down', and you can differentiate the characters. In reality, you're simply learning to hear these tones quicker.

You should concentrate on how each character sounds, and don't rely on a visual representation of the code. Listen to the characters, and hear the rhythm of each one. You will hear Morse Code sent at 20 Words Per Minute (WPM), sent at full speed, from the very first lesson. These tones are purposely sent too fast to count the beeps. You should be training your ear to hear the sound of the character, like you hear the sound of a word. Listen when you are able concentrate on what you're doing, and not overburdened with other activities. Remember, this should be fun. Enjoy the process. So, when you're ready, sign up for the free reminder emails right here, and start with lesson 1, we hope you'll make it through the 40 lessons, and LearnMorse!

New To Radio / Re: HT Programming With Chirp

Hi Mark, and welcome to the board! :)

I assume the quote below from miklor.com is what you mean.

The Tones are like a key your radio transmits to unlock a repeater that is "locked" with CTCSS(continuous tone coded squelch system).  In some areas there are repeaters that share the same frequency and are close enough that one will hear the other and re-transmit it.  Or some areas just have a lot activity on the frequencies, some of which happens to be on the repeater's frequency.  Repeaters with Tone Squelch require the incoming signal to have a specific frequency (continuous tone) along with the voice before it will re-transmit the signal.  These tones are always below 250Hz.  Since voice bandwidth is 300Hz - 3KHz, the radio filters out everything below 300Hz and you never hear the tones, but the repeater does.

All modern HTs will not only broadcast the tone you program into them, but you can set it so it will ignore incoming signals without the tone you programmed it for.  That can be handy if the band is full of chatter.  Some repeaters put out a tone, so you can set your radio so it's squelch will only open with the repeater's tone.

Here's a Wikipedia page on CTCSS.
https://en.wikipedia.org/wiki/Continuous_Tone-Coded_Squelch_System

Tone ModeThis sets the mode used to transmit or receive squelch tones (or related selective calling technologies). The following explains what the options means:
  • (None): No tone or code is transmitted, receive squelch is open or carrier-triggered.
  • Tone: A single CTCSS tone is transmitted, receive squelch is open or carrier-triggered. The tone used is that which is set in the Tone column.
  • TSQL: A single CTCSS tone is transmitted, receive squelch is tone-coded to the same tone. The tone used is that which is set in the ToneSql column.
  • DTCS: A single DTCS/DCS code is transmitted, receive squelch is digitally tone-coded to the same code. The code used is that which is set in the DTCS Code column.
  • Cross: A complex arrangement of squelch technologies is in use. See the definition of the Cross Mode column for details.

Hello, I don't remember and unfortunately lost my boat, but if you find measurements for the Morris Frances 26 you will have your answer...

Hello forum member's, I am a new Ham and I have a mental disability. I don't understand the "Column Definition" regarding Chirp software on the miklor.com website. Would someone please explain "Tone Modes" for me? Thanks in advance and 73!

There was some USA/EU reports on the RBN for 30m... No long QSO on my part, only the one from the 17th, also on 30m, lasted 11 minutes...

At 18:40 I'm hearing half of a long QSO on 10,117, but it's so faint and QSBing in and out that I haven't picked up any call signs.  RBN shows lots of hits, but none are across the Atlantic.  My DroidProp app makes lit look like 10m will open up between us a bit in the next hour.
