80-6 Meter Windom Dipole Antenna

I am in hopes to get my new 80-6 Meter Windom Dipole Antenna up this weekend at my house. This is an 80-6 meter, 7-band (80/75, 40, 20, 17, 12, 10, 6 meters), Windom antenna. An antenna tuner is not required. The antenna is very broad, providing <2:1 SWR across each band segment. I'm using the internal tuner in my radio to match the antenna. The total length of the antenna is 132 ft. with one leg being 88 ft. in length and the other 44 ft. Power handling capacity is conservatively rated at 2kw PEP. The wire used in this antenna is insulated 14 gauge stranded copper wire. The impedance of the Windom antenna is approximately 50 ohms with the built-in 4:1 balun so it is compatible with standard coaxial feedline RG-58 is what I am using. T he balun is built around a large type 43 ferrite core for coverage from 100 khz. to 60 mhz. Weather looks clear lets hope for the best.

ARRL May Seek HF Data Privileges for Technicians

Among other actions taken by the ARRL board of directors at its July meeting, it tasked its executive committee with looking into the possibility of seeking “ limited RTTY/data privileges for Technician licensees on 80, 40, and 15 meters ,” according to a summary in the ARRL Letter. Techs currently have only CW (Morse code) privileges on those bands. http://www.arrl.org/news/arrl-board-lauds-unforgettable-milestone-formalizes-lotw-policy-honors-award-recipients

Backup Power and Generators

Generators come in two basic types: standby and portable. The source of backup power you ultimately choose will be determined by many factors, including your power requirements. A standby generator is permanently installed outside your home or commercial building and wired directly into the electrical system to provide power to some or all of your home’s circuits during a disruption of normal utility power. Depending on the model, they may start automatically when the power goes out and stop when the power returns. Standby generators are fueled by liquid propane or natural gas and require professional installation, often with a permit. The number of circuits to which a standby generator can provide power–and the number of appliances you can run on those circuits–is determined by the power capacity of the generator. Standby generators are typically fully enclosed and vary in size. Check the dimensions carefully. A standby model may cost as little as $1,500 or as much as $15,000
