Reverse Beacon Network
Identify band openings, see if you are getting out, and discover other CW operators on the air.
NCDXF/IARU International Beacon Project
World-wide beacon network that broadcast on a rotating schedule across 14.100, 18.110, 21.150, 24.930, and 28.200Mhz. The beacons send at 22wpm followed by four one-second dashes sent at 100, 10, 1, and 0.1 watts. At the end of each 10 second transmission, the beacon steps to the next higher band and the next beacon in the sequence begins transmitting.
Free professional HF propagation prediction software from NTIA/ITS, and originally developed for Voice of America (VOA).
Web application for HF propagation prediction. Excellent and easy to use!
WWFF (World Wide Flora & Fauna)
Another popular option for hiking summits and getting on the air. CW is frequently used!
Compendium of Automatic Morse Code by Ed Goss (N3CW). It is an excellent hardback book with informative text and over 1,100 high-quality photos covering Morse code devices from the early 1800s to today. (The link provided goes to Amazon, but it is available from other retailers.)
CQ Serenade by Maurice Durieux, VE2QS
This is a delightful song produced sometime between 1965 and 1970. Words and music by the late Maurice Durieux, VE2QS, symphony conductor, arranger, and violinist, VE2BR, Noel Marcil. Vocals by Ms. Joyce Hahn.
Communication by Slim Gaillard
Catchy song calling out CQ (Dah Di Dah Dit, Dah Dah Di Dah).

Morse code versus T9 Texting
Jay Leno set up a runoff between old and new school technology on The Tonight Show on May 13, 2005. Chip Margelli (K7JA) was at the key, while Ben Cook, the Guinness World record holder for speed text-messaging, sent a text message.

Highly sensitive CW decoder that simultaneously decodes ALL CW signals in the receiver passband. There is a free 30-day trial. Afterward, a $75 registration is required.
ARRL VE 20 WPM Morse Code Tests:
The Morse code proficiency requirement was removed from the Amateur Radio Service Part 97 rules on February 23, 2007. Until that time, the Amateur Extra class license required proficiency at 20wpm. Below are tests used to qualify applications.

McElroy Chart of Codes and Signals Poster from 1942:
Displayed prominently in the upper right is Theodore "Ted" Roosevelt McElroy. He was at first an American Morse wire telegrapher but later a radiotelegrapher. McElroy holds the world's record for copying five minutes of error-free Morse sent at 75.2 words per minute.

AI Assisted Decoding
Check out this fascinating experiment by AG1LE to decode Morse code down to -3 dB SNR. Advances in artificial intelligence and machine learning are enabling new approaches to decoding morse code. Perhaps it is a matter of time before machines will perform better than even the most proficient operator at decoding Morse code under challenging conditions.
