Crumbs Jan. 14
New Year Greetings to all
We began the New Year with a big turn out for one primary reason. Our dear friend Frank K6BDK who is leaving us for pastures new in Bend Oregon. I have known Frank for a mere 22 years and many present go back much further. Frank has regularly attended our CAKE sessions and is well regarded for his acute questions and insights. We are pleased to learn that he will be able to put up some decent antennas and that we will meet him on the air soon. He intends to stay in touch. Photos by Bob K6XX.
Those present to wish him God-speed were Bob K6XX, Ron K6EXT, Cap KE6AFE, JV K6HJU, Don K6GHA, Chuck W1WUH, Glen KG0T, John N5HPB, Peter K6UNO, Reed N1WC, David KG6IRW, Fred KJ6OOV, Tom KW6S and Ron W6WO
The items of interest that were up for discussion included a module from the original computer used in the development of Fortran, a GPS receiver in a very nice enclosure, a print from the 1900s of a CW pulse that went round the world 3-times and the QRP-Labs WSPR/digital mode beacon transmitter.
Thanks to all for showing up today BCNU in future CAKE sessions
PS Thanks for the chocolate CAKE Don !
Early US Navy Radio Communications
I recently passed through the Panama Canal for the first time. While impressive, the shear magnitude of the project wasn’t clear until I looked at a collection of photo graphs taken during the years of construction 1904-1914. To my mind this achievement is at least par to landing a man on the moon.
The first picture shows the USS Ohio passing through in July 1915. I speculate the twin towers are LF and MF antennas. because prior to 1923 amateurs had not proven the value of short wave communications to the world. However the similar picture of USS Texas circa 1919 also shows what appears to be HF antennas. Maybe there were some Hams aboard ! By 1930 the pictures of US ships had no such towers.
I know Art Lee WF6P would have enjoyed perusing these pictures and It is with great sadness I learned of his passing. He will continue to be greatly missed
Noise Floor Report does not inspire confidence
By Dan Romanchik, KB6NU
Last June, the FCC’s Technical Advisory Committee asked licensed and unlicensed users of the electromagnetic spectrum to answer some questions about the noise they were experiencing and whether or not it was affecting their services. Specifically, they asked:
* Is there a noise floor problem?
* Where does the problem exist? Spectrally? Spatially? Temporally?
* Is there quantitative evidence of the overall increase in the total integrated noise floor across various segments of the radio frequency spectrum?
* How should a noise study be performed?
Well, the results are in, and Radio World recently published a summary of the responses that the FCC received (http://www.radioworld.com/business-and-law/0009/noise-floor-where-do-we-go-from-here/338242). The FCC received 93 replies from 73 (great number, eh?) different people or organizations, including:
* 23 companies/industry organizations
* 39 RF professionals (broadcast and wireless)
* 31 licensed radio amateurs
* 9 responders did not reply to the questions asked
Respondents included the ARRL, the Society of Broadcast Engineers, the National Association of Broadcasters, the National Public Safety Telecommunications Council, ATT, and the National Electrical Manufacturers Association. I found especially interesting comments from the Society of Broadcast Engineers. They include:
* Increased cooperation is needed between manufacturers of Part 15 devices and users of radio spectrum to identify noise sources and take appropriate remedial action.
* Radiated emission limits below 30 MHz in the FCC Part 15 rules for unintentional emitters should be enacted. There are presently no radiated emission limits below 30 MHz for most unintentional emitters.
* Reduced Part 15 limits for LED lights should be enacted to be harmonized with the Part 18 lower limits for fluorescent bulbs.
* Better labeling on packaging for Part 18 fluorescent bulbs and ballasts to better inform consumers of potential interference to radio, TV and cellphone reception in the residential environment.
* Specific radiated and/or conducted emission limits for incidental emitters, such as motors or power lines, should be enacted.
* Conducted emission limits on pulse-width motor controllers used in appliances should be enacted.
* Substantially increase the visibility of enforcement in power line interference cases.
Other organizations made similar comments.
While the report is encouraging, it won’t mean a thing if no action is taken on these issues. Given that the FCC is cutting back on its field offices, and our president-elect has said that he plans to reduce the number of governmental regulations, I’m not optimistic that we’ll see the noise situation get better before it gets worse.

Arthur “Art” Lee, WF6P SK
Nov. 19, 1928 – Dec. 12, 2016
Arthur R. Lee, age 88 of Santa Cruz, CA passed away on December 12, 2016. Arthur was born in San Diego, California on November 19th 1928. He attended schools in Hawaii and high school at Hayward High and earned a Bachelor’s Degree in Business Management and a Master’s Degree in Public Administration from San Jose State University. As a 13 year old Navy dependent at West Loch, Hawaii, he and his family witnessed the bombing of Pearl Harbor and took refuge when his home was strafed by Japanese aircraft. Like his father LT Harry C. Lee, he joined the Navy in 1946 at 17 years old and served his country with honor and distinction for 30 years, retiring as a Commander in 1976. His military service included ship tours aboard the aircraft carriers Oriskany and Ranger. He served in both the Korean andVietnam wars and was awarded the Purple Heart along with numerous other commendations for his courage and leadership.
Following his naval career, he was a teacher and mentor, teaching aviation maintenance management at Embry-Riddle Aeronautical University; Aeronautics, Amateur Radio and Magazine Article Writing at Cabrillo College. He enjoyed many years sailing a wide variety of vessels in Hawaii, Vietnam, Guam, Japan, San Diego and Santa Cruz. He also enjoyed Amateur Radio and was active in that community for many years, helping to track sailing vessels during countless transpacific journeys. He was a prolific writer. His work appeared in a wide variety of publications including the Wall Street Journal, Naval Institute Proceedings, Popular Electronics, Yachting, Smithsonian and many more. He especially enjoyed sharing his love of writing with other writers.
Arthur was a master storyteller. He entertained many with his humorous and poignant stories about the sea, military life, Masonic service, and the many people he met throughout his exciting life. He loved music of the golden era and enjoyed playing the piano with fellow musicians. He was a lifelong tennis player, Mason and sailor and kept active in many clubs throughout his entire life.
Arthur married Donna Vermette on March 7, 1952 and enjoyed a wonderful 64 years of marriage. (Arthur freely admits they started their family 9 months and 1 day after they were married). Arthur is predeceased by his brother (Stanley). Arthur is survived by his wife Donna, brother (Clinton), sisters (Barbara and Sylvia), two daughters (Joyce and Elaine), two sons (Bruce “Steve” and Randal), seven grandchildren (Cheri, Eric, Beckett, Shannon, Justin, Benjamin and Samuel, five great-grandchildren (Brooklyn, Preston, Theodore, Madelyn and Chelsea).
