Jan 2014 Update -I now have a "grower" with a license to produce cannabis located a quarter mile away. The problem centers on eight 1kw RF grow light ballast generators each producing a form of 120 KHz square wave output where every one have over 1000 volt pk to pk on the fundemental and being square waves they gernerate rich harmonics across the radio frequency range from below 160 meters to well above 40 meters. The noise interference is over S8 or S9 from a 1/4 mile away. Unless the consumer is familiar with electronics and has EMI experience the users will not understand the high level of noise interference. The FCC certification violation for RF radiators is beyond the consumer. Part 18, subpart 18.209(b) describes how these should appear with the FC label for approved devices. They are made in China under various models and names. They are imported and sold through many e-commerce and distribution channels but all operate with similar circuit designs.

The FCC Rule is shown here:

http://www.gpo.gov/fdsys/pkg/CFR-2010-title47-vol1/pdf/CFR-2010-title47-vol1-part18.pdf

The importers of these devices should be fined for selling them. The growers can continue with magnetic ballasts clean of any RF interference or the importers can have their Asian suppliers work on an upgrade in technology by offering high efficiency LED grow lights to replace their illegal digital products. Here is a You Tube link to a recording of the noise on 80 and 40 meters plus on the WWV frequency of 5000 MHz

AMATEUR RADIO BIOGRAPHY

55 years of Low Band DXing from New England, Japan and California.

Paper Log Contesting History:  As KA7AB in Japan, won  ARRL DX Contest Asia High Score Plaques in 1967&1968 for both Phone & CW.  CQWW, 1967, CW Top Ten and high score for Asia  As K1KTH, Single Operator All Band, won CQWW DX Contest,  USA High Scores, Phone 1969 & CW 1970. Awarded Patomac Valley RC and Frankfort RD trophies

1975 to 2000 Former call sign, N6JL with a location in Santa Cruz Mountains that long path operators dream about only if they had the chance to know what it's like to operate at 2800 feet looking to the ocean from NNE thru west to SSW. For this location I designed and built a dual band array for 80 and 160 meters suspended 250' above a canyon on my 12 acre property. Also installed 80 ft rotating self-supporting tower with 4-ele 20-meter beam, 40-meter dipole and dual band 3-ele 15/10 meter beams mounted at the top. All survived the great 89 Loma Prieta Earthquake...

I began my ham activities in 1959 as K1KTH from Lincoln, MA. I met Dana Atchley, W1CF (W1HKK) who found me in the neighborhood looking to be a weekend helper with his antenna projects. It was then that I discovered the art of low band antenna experimentation and construction. I had the pleasure of operating his station in the ARRL Phone Sweepstakes achieving the top New England score and 10th overall in 1961.

1965 to 1968 while in the USAF, I set up a station in Southern Japan with the call sign KA7AB operating from  the Island of Kyushu.

Beyond contesting from there, obtaining the first KA authorization to operate on 80 meters was key to making many DX contacts via the gray line to the east coast of the USA and Sam Harris, W1FZJ/KP4 almost all year round, both on SSB and CW. For most all in the northeast of the USA I gave them their first Phone contacts with Japan.

Upon return to the USA in 1968 I built a DX contest station with two towers, 4 homebrew rotary beams and sloping dipoles for 80 meters located outside Boston.  

2007 to present I'm now retired and live on a 30 acre farm in Maine.  N6JL was traded in for the vanity call W1QS. It took many years of hard work to reach a point where there is time to have this farm and be able to get back on the air.

The 80 and 40 meter 4-Square phased vertical site is 300 ft east of the farm house. The antennas are fed with 7/8" Heliax running underground from the house to the site. I met my goal of completing construction before the end of 2009. A pair of phased top loaded verticals for 160 meters and two bi directional 800 ft Beverages will be added shortly. Due to my noise problems I've decided to pospone my 160 meter plans until it is resolved via FCC action. 

Other activities include breeding Morgan horses, sailing in Maine and maintaining the farm. I volunteer my professional expertise in broadband wireless services and mission critical communications.  This is my version of living "The Good Life" retired with my xyl, Marcia.

73,

John, W1QS exN6JL, K1KTH and KA7AB
