RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

On the May 13, 2005 episode of The Tonight Show, Jay Leno held a speed contest between two Ham Radio operators using Morse code and two Millennials using their smartphones for texting (SMS). At least one member of the audience thought texting would win. Watch the video to see if they were right.
Mr. Chip Margelli (K7JA) did the sending. He declares, "Let me assure you that we never saw that message before I flipped the blue card over. Each message, in rehearsal, was different. The character count was the same as the one during dress rehearsal, though, to account for the time slot. And they put the card on the table "upside down" creative to how I flipped it, as you can see on the video."
Mr. Ken Miller (K6CTW) did the receiving.
The text messaging team consisted of world text-messaging champ Ben Cook (Guinness record holder in 2004, 2005, and 2009), of Utah, and his friend, Jason.
A detailed synopsis of the event is provided in the May 20, 2005 issue of The ARRL Newsletter. It gives radio equipment models (Yaesu FT-817 transceivers and a Bencher paddle) and the transmitting frequency (432.200 MHz). The Hams say the code sending rate worked out to about 29 words per minute (WPM), which is about half their capability under ideal condition (i.e., without a 20-million-strong TV audience).
This collection of video and a few audio files represents files that have been featured on the RF Cafe homepage. Every week or so a new file is added that should be of interest to RF Cafe visitors.
Please send me an e-mail if you have a good subject. Note: "Videos for Engineers" formerly went by the name "Cool Videos."
