1 CW by Jim Stafford, W4QO

2 CW What is CW? Continuous Wave – Morse Code “Invented” in 1836 Samuel FB Morse, Joseph Henry, Alfred Vail A system of transmitting signals over wire A telegraph system Didn't actually use “the code” until 1844 Dots and Dashes on a paper tape

3 CW What is CW? A language with only about 44 words By the civil war, thousands of miles of telegraph wires When radio came along (1900), no one saw a use.. Except the NAVY Because why use radio when there was telegraph BUT ship to shore was what was needed All early RADIO communication was via Morse Code AND “ham operators” used it for fun and messages. No more Morse in commercial use past 1999.

4 CW A blast from the past Thomas Edison sending telegraph CODE This was recorded by a friend of a friend of my elmer Pat Moran, W2EM A great telegrapher in his own right. Pat belonged to a club which used a circuit to convert off the air CW to key a telegraph sounder.

5 CW Why Hams use Morse Code? It's FUN! People did not stop painting, with photography! People did not stop bicycling once there were cars! People did not stop sailing after steamships!

6 CW No longer required for licensing BUT Listen down in the CW bands on most weekends and see all the fun people are having. The original DIGITAL mode (using your own digits) Opens up much more of the richness of ham radio Auditory – not visual – learn by ear

7 This new language has only 46 words – 26 letters, 10 Numbers, and 10 symbols How does this compare to Latin?

9 WHY CW? (remember FUN!) 1. Works when other modes do not “get thru” 2. Easier to build transmitters that do CW 3. It's the international language; heritage 4. CW use seems to be GROWING, scuttlebutt? 5. It's a natural for QRP (see #1 and #2) Combining multiple hobbies: hiking, camping, kit building. 6. Kids who learn CW think it's cool! 7. CW ops are the friendliest and most helpful 8. It can save your life – flash your car headlights! Everyone should know your callsign and SOS But probably one of the major reasons is …..

11 How to learn CW Go to nfarl.org and their CW SIG page Go to my blog: w4qo.blogspot.com My mother taught me the CODE! Do not use the KOCH method – what is that? It was used by the German army to teach code to troops. Fall behind in your learning and ship off to the Russian Front! Use the Farnsworth method and CW PLAYER program Then use the approach outlined in my blog – learn ESTONIA first 58 of my files for practice are on the nfarl.org site For tips, visit Yahoo reflector: groups.yahoo.com/group/atlCWsig/

12 CW SIG Nineteen Estonians sent a note to a no nonsense tootsie  Learn CW! ESTONIA in week 1  Meets Jan weeks self study  On the air (M-W-F) practice & tests  Hosted by Jim, W4QO at his QTH  See Jim at a side table to sign up or get questions answered

14 CW On CW PLAYER Download/install Set speed to 5/18 Here is the “order”: ESTONIA DR MULCH PFWYGB JKQXZV etc

15 CW On CWP Pick SELECTED CHARACTERS Use some letters From ESTONIA Such as A and T, Then add more Next get files from NFARL.ORG

16 CW Straight key is way to start as it develops good spacing and characters. IMHO -Paddles can come later. With enough practice, you'll develop a musical fist and you'll be ready for faster sending with paddles. But … Some people begin with iambic paddles and electronic keyers. The only "best" method is what works for you. Forget about a bug. It’s a mechanical monster from the past. It’s like an antique car; if you want one! Most modern HF rigs have a CW "practice" mode, so if you have an all-mode rig you probably won't need to purchase or build a code practice oscillator.

17 Ways to send Morse Code Straight Key > Paddle/Keyer Bug

18 CW Don’t buy this key  Get one off ebay such as … Currently $18.70 incl shipping Should be able to get a J-38 or J37 for under $35 incl shipping

19 Or make your own….

20 Want to increase your speed? Use the program RUFZ from rufz.net It's like hitting golf balls on the practice range Developed to help Eastern EU high schools Sends you callsigns – increases or decreases speed Files available on NFARL.org for N. American calls

21 RUFZ TIPS - It uses characters per minute, not WPM; so use 65 - It plays a callsign; if correct, increases speed - If incorrect, it decreases speed - It gives you a score at the end of each session - Details of how to load and use NFARL.org (CW SIG)

23 Key Points you should know 1. Learning CW is easy – remember only 44 words! 2. Sending is important – send ¼ of the time 3. Get on the air – best practice – make contacts 4. After learning ESTONIA and DR MULCH, get on air 5. Look up and tune in W1AW code practice 6. Start with a straight key OR paddle 7. Eventually Listen to CW without writing it down 8. Set yourself up a DAILY practice schedule 9. Join a CW club – FISTS or SKCC (a free one) 10. Read the “Art and Skill of Radio- Telegraphy”
