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.
Morse Code opening scene on The Office (US version)
In an opening scene of The Office, Jim and Pam torment Dwight with their newfound skill of sending Morse code. Of course, they aren't actually sending Morse code, but it is a hilarious and delightful pop culture reference.

History of Telegraph Lines:
This fascinating video dives into the history of the telegraph to see just what made the telegraph, and Morse Code, a success. The American Telegraph was one of the first advancements toward the near-instant communication of today. While the telegraph found its origin in Britain, it hit its stride in the United States with Samuel Morse’s design, gaining international prestige and even a cable running across the Atlantic Ocean.Jean Shepherd 1965 WOR Broadcast:
Listen to this fascinating 40 minute broadcast from 1965 of Jean Shepherd discussing Morse Code, Signal Corps Code School, and Propagation! For context, Jean Shepherd is a famous amateur radio operator and is best known for his role in the film A Christmas Story. This was aired from WOR, an AM radio station that began broadcasting in February 1922. It is one of the oldest radio stations in the United States.
The last radio station:
KPH was the last commercial ship-to-shore maritime radio station in North America. This heartfelt 10-minute documentary covers their last transmission on June 30, 1997, and its return as a historical site several years later.
New Zealand (1939):
This fascinating and short 11-minute, 1939 documentary demonstrates how short-distance telephone, long-distance landline telegraph, and wireless telegraphy allow a simple birthday greeting from parents in rural New Zealand to reach their son traveling aboard the steamship Queen Marry far out to sea.
Radio Hams (1939):
Watch this fun and humorous 10-minute film that provides insight into amateur radio's culture, its simple beginnings with homemade radios in the early 20th century, and how hams play a serious role in responding to emergencies. The video features aircraft using morse code during an emergency.
Research on the learning of RadioTelegraphic Code:
A fascinating research paper on Morse Code from Harvard University released in the Journal of Psychology in July 1943! The outbreak of World Word II created a massive demand for the United States to train men in the use of the International Morse Code, perhaps as many as 10,000 men per month! The problem was that 30 to 60% of men entering radiotelegraphy schools failed to become proficient operators. The author, Donald Taylor, carried out experiments to determine aptitude and ways to shorten the length of time necessary to train men to become proficient with Morse code. The results are fascinating! And some of it goes against commonly held beliefs in the amateur radio community even today!
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.
Reverse Beacon Network
Identify band openings, see if you are getting out, and discover other CW operators on the air.
- For checking propagation at your location, consider sending "CQ RBN CQ RBN VVV VVV DE CALLSIGN CALLSIGN K". Send at any speed, but be sure that your CW is clean, and the characters are properly spaced. Then see where you are heard on the live spots page. On that page, click the "search spot by callsign", put in your callsign, and then click the "search" button. The page will show one or more RBN stations that copy you, and at what signal strength in dB.
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.
