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 producing a form of spread spectrum emission (designator unknown) output across the radio frequency range from below 160 meters to 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:


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

54 years of Low Band DXing from New England, Japan and California. Now what?

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. 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 beam 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 acquired the call sign KA7AB and operated on the Island of Kyushu, Southern Japan.

Contest achievements from Japan: ARRL DX Contest- Asia high score plaques in 1967 and 1968 for both Phone and CW. In the1967 CW CQWW DX Contest was top score for Asia and in the "Top Ten" world wide.

Obtained the first KA authorization to operate on 80 meters and enjoyed 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 many in the northeast of the USA I gave out their first Phone contacts with Japan.

Upon return to the USA I built a DX contest station and won the CQWW DX Single Op All Band Top USA Score, Patomac Valley RC Trophy for Phone in 1969 and the Frankfort RC for CW in 1970.

I'm now retired and live on a 30 acre farm in Maine and traded in N6JL for the vanity W1QS callsign. It took me a few years to reach a point where there is time on the farm for getting back on the air after being QRT for about 10 years.

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 proplems 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.
