So I decided to try CW Why? n How? n Morse Machine n Rufz. XP n Just Learn Morse Code n Morse Runner n G 4 FON Koch Trainer n CWCom n Morse. Cat n Begali CW Machine n
Why n n n 5 Dx stations on CW for every SSB on 17 m Less Bandwidth Less power Wanted to prove that I can. Says something about perseverance and dedication CW & Antennas are likely the most discussed topics.
How long will it take?
How - Tools n n n Software. Rx only initially Every program had a specific strong point for me. All S/W in this discussion is free. Sending is Easy – or so they say. CWCom for sending feedback
How - Technique n n n n n Learn single chars first. Recognize sound of char. Verify correctness initially Continuous copy. Short chars easy to learn but difficult during continuous copy. Copy on paper Copy in head I always copy call on paper. (even for voice) Avoid “auto complete”
Morse Machine n n Pro’s u Good to get started u Char training only. Cons u No audible error indication u Chars not totally selectable. u No space distinction.
Rufz. X P n n n Rufzeichen-Hören 50 calls with top score. Calls only – no words. Pro’s u Speeds up Cons u Not learning the space between words. u Tend to predict the numeric.
Just Learn Morse Code n n n Can define what chars Used extensively to practice 5/h Hear and see to learn Hear and type to test Good for learning letters Shows correct percentage feedback
G 4 FON Koch Trainer n n Good for words / QSO etc. Simulates various real world conditions: Signal strength u Noise Level u QSB u Chirp u … more u
Morse runner n n n Simulates Contest Simulates band conditions. Simultaneous calls QRM Call and seq no.
Morse Cat 2. 0 n n n Does char training Lessons Expert mode allows fine tuning Simulated calls Copy on paper and check Sending check training no longer available.
MFJ-418 Pocket Code Tutor n n n n Portable Typical MFJ quality. Quality deteriorated on later models. Letters, Words, QSO’s etc. Interactive or continuous. Farnsworth timing. Words & QSO somewhat outdated
Sending n n n Always start with straight key 20 WPM seems to be average high end for straight key. Move on to paddle or bug. Most folks seems to use dual paddles. Verify “fist” with CWCom or Begali
Begali CW machine n n n n Top of the line Keyer $300 + Software Tutor Logger Interfaces with PC Interfaces with Keyboard. Interfaces with straight Key or Paddle.
CWCOM n n n Like AIM with CW Supports straight key and paddle through serial port Special characters can be defined
Timing n n n (copied from ZART) Dot is the base unit of measure A dit is the sound of one dot followed by the silence of one dot. A daah, the sound of a dash, is 3 dots long followed by the silence of one dot. The space between letters is 3 dots. The space between words is 7 dots.
Measuring speed (copied from ZART) n n n n Based on the word: PARIS P: 11 dots + 3 letter spacing. A: 5 dots + 3 letter spacing. R: 7 dots + 3 letter spacing. I: 3 dots + 3 letter spacing S: 5 dots. Total: 50 dots (including the word space at the end).
The First QSO n n n n Listen on the air to get a feel for the structure of the typical QSO. Listen to hear that other folks make mistakes. Listen to hear that there are many slow QSO’s Become familiar with the abbreviations e. g. fer, fb Become familiar with the prosigns KN, AR, SK etc. Prepare a template QSO that you can copy from. Practice the template with CWCom. Get an Elmer for the first one. .
