“Log Periodic Antennas” is the topic of the current (January 3) episode of the “ARRL The Doctor is In” podcast. Listen…and learn!
A log-periodic antenna , also known as a log-periodic array or log-periodic aerial, isa multi-element, directional antenna designed to operate over a wide band of frequencies. It was invented by Dwight Isbell and Raymond DuHamel at the University of Illinois in 1958.
The most common form of log-periodic antenna is the log-periodic dipole array or LPDA, The LPDA consists of a number of half-wave dipole driven elements of gradually increasing length, each consisting of a pair of metal rods. The dipoles are mounted close together in a line, connected in parallel to the feedline with alternating phase. Electrically, it simulates a series of two or three-element Yagi antennas connected together, each set tuned to a different frequency.
It is with a heavy heart that I report the passing of long time QCWA Chapter 6 and Bum o’ the Month member, Bruce Murray, N3GHI, on 6 January 2019. Bruce was the last of our WWII veterans having flown with the 487th Bomb Group, 8th Air Force, as a B-17 crewman. Funeral arrangements are unknown at this time.

The first Breezeshooters Ground Wave CW Contest is Feb 16th from 8pm to midnight ET. . The Breezeshooters Ground Wave Contests usually fall on the 3rd Saturday evening of the months of February is CW, and March is SSB.
This year they are:
- February 16 CW mode. CW portion of the Ten Meter band.
- March 16 SSB mode in the phone mode portions of the Ten Meter Band.
Time: 8 pm to midnight ET for all contests.
Where: Ten Meter Band within specific portions of the ten meter band, depending on operating mode.The communications exchange between stations is: CALL SIGN and GRID Square Number. The GRID Square is based on a specific local geographic area location. The participant can determine their Grid Square number from the enclosed map in the attachment. As an example if you are in Allegheny County the Grid Square is most likely 25. Please note this contest Grid Square is not the same as used in various VHF/UHF contest, such as falls in the format FN00xx. It is a two digit number numbered from 1 to 49.
For more information: http://www.breezeshooters.org/ [When posted]
Date and Contest Period: The date will be announced annually by the ARRL but will generally be the third or fourth weekend in January. Begins 1900 UTC Saturday, ends 0359 UTC Monday (January 19-21, 2019).
Objective: For amateurs in the US and Canada (and their possessions) to work as many amateur stations in as many different 2 degrees x 1 degree Maidenhead grid squares as possible using authorized frequencies above 50 MHz. Stations outside the US & Canada (and their possessions) may only work stations in the US (and its possessions) and Canada.
All legal modes are permitted (while CW and SSB/Phone are most common, MSK144, FT8 and FM-Only are gaining popularity – other popular modes include PSK31, FSK441 and JT65). For Cabrillo file mode definitions, Digital modes should be represented as “DG” (for all things digital) or “PH” or “RY” can also be used as digital modes are transmitted via Phone audio.
Stations in KH0-9, KL7 & KP1-KP5, CY9 and CY0 count as W/VE stations and can be worked by DX stations for contest credit.

Winter Field Day Association (WFDA) is a dedicated group of Amateur Radio Operators who believe that emergency communications in a winter environment is just as important as the preparations and practice that is done each summer but with some additional unique operational concerns.
We believe as do those entities of ARRL Organizations like ARES & RACES that maintaining your operational skills should not be limited to fair weather scenarios. The addition of Winter Field Day will enhance those already important skills of those that who generously volunteer their time and equipment to these organizations. This is why WFD is open to all licensed amateur radio operators worldwide.
Disasters are unpredictable by nature and can strike when you least expect them. WFDA’s goal is to help enhance your skills and ready you for all environmental conditions found in the US and Canada during the spring, summer, fall and winter Preparedness is the key to a professional and timely response during any event and this is what local and state authorities are expecting when they reach out to the emergency service groups that offer their services.

Major Changes to ARES and OO Programs
The ARRL Public Service Enhancement Working Group has completed its two-year project to re-tool the Amateur Radio Emergency Service (ARES) to meet the requirements of partner agencies, nationwide. The new program will consist of ARES Members who are “organized, trained, qualified and credentialed” to better serve our partner agencies.
The new program features three levels of ARES membership, which are matched by three levels of required training and certification. The training requirements will be met by members completing free, online courses including NIMS IS-100, IS-200, IS-700 and IS-800 and the newly revised ARRL EC-001, which will be provided free of charge to ARES members. Additional training is required for all ARES leadership appointees (“*ECs”).
The ARRL Board has opened a public comment period which runs until October 31. ARRL requests your comments to be sent through your Section Emergency Coordinator <email@example.com> and Section Manager <firstname.lastname@example.org> only. The Board will review all comments and vote on the final program at the January 2019 ARRL Board Meeting.
The current OO program will end, and be replaced by a new Volunteer Monitoring program, administered by ARRL HQ, working closely with FCC. All current OOs will be invited to apply for the new program, which will concentrate on major enforcement issues the FCC requests. The goal is to provide more rapid enforcement response to significant, developing on-the-air violations rather than more minor operating and technical issues.
Much more information about these developments is available online at www.arrl.org and in upcoming issues of QST.
Every day is a good day to send CW, but January 1 is reserved for Straight Key Night. Enjoy CW as it has been sent and enjoyed since the earliest days of Amateur Radio. This 24-hour event is not a contest; rather it is a day dedicated to celebrating our CW heritage. Participants are encouraged to get on the air and simply make enjoyable, conversational CW QSOs. The use of straight keys or bugs to send CW is preferred. There are no points scored and all who participate are winners.

Times: January 1 from 0000 UTC through 2359 UTC
