I have a full size 160M horizontal dipole -- 120 feet high -- and an array of four 1/4 wavelength verticals with an extensive buried radial system. Except on rare occasions, DX signals are always at

Paul, The snippet quoted from the Proceedings is the root of the confusion about the 1BCG antenna. The 78 page Proceedings documents the antenna, the entire station, and Godley's DXpedition to Scotla
see e-mail from W3YY below: I recently received a QSL card from Remi, FK8CP, for QSO's on 160, 80, and 17-meters. (I especially love that 160 contact!) He included a letter describing his needs for s
Hi Paul, As a rule of thumb, the length of the vertical wire and half of the T top should be approximately 135 feet total. Your antenna is too short, its probably resonant at approximately 2.5 MHz. Y
My neighbor W3UR secretly installed several of these in his shack a few months ago. He worked H44MY last month but I could't even hear him, and Bernie and I share the same antennas! http://www.parts-
75 ohm BNC connectors are specialized connectors used primarily above 100 MHz by in high definition television production studios, telephone, and satellite communications industries. Unless you work
Hi Ed, My 160 meter 4-square array uses two 125 foot towers and two vertical wires suspended from catenaries. When I initially tuned the array I discovered that the resonant frequency of the wire ele
Hi Bill, Each of the verticals in the W5ZN eight-circle array is designed to be guyed with four guy wires. The upper 25 feet of the guys form a top hat that is an intergal part of the antenna. The ve
Hi Mike, Raising your Beverage by a few feet over a short distance will have no affect at all. 73 Frank W3LPL -- Original message -- _______________________________________________ UR RST IS ... ...
Hi Brendan, You'll have an arcing problem if you lay chicken wire directly on radials with no insulation. You could avoid this if you bond the radials to the outer edge of the chicken wire, but this
Larry, Diversity reception with the two identical K3 receivers takes essentially no extra effort. In diversity mode, the two receivers are locked together and any tuning or bandwidth change made on o
In the last few weeks a new strong variable frequency 100% duty cycle RFI source suddenly appeared on 160 meters, radiated from a home one mile southeast of my QTH 24 hours per day. The RFI peaks in
Hi Rick, Obviously something is very wrong with your new Beverage. While your Beverage is too short for really good performance on 160 meters, it should perform very well on 80 and 40 meters. Please
Mark, While "The Benchmark Beverage" makes interesting reading, it conflicts significantly with years of practical Topband experience. The credibility of "The Benchmark Beverage" suffers badly becaus
I'm not the only ham with this 160 meter RFI. W2GPS and I were discussing this today, and Rick recalled that he's seen nearly identical RFI on 160 meters at his QTH 30 miles from here for several yea
Hi Bob, W2GPS are not hearing the same RFI source, we are hearing two RFI sources with nearly identical characteristics. I have successfully identified the source of my RFI. W2GPS isn't very concerne
Hi Larry, Congratulations on finding that neutral arc! I've never had any difficulty isolating neutral arcs to an individual pole by using a 400 MHz receiver, but your experience may be different tha

Phil, How about using a selsyn to turn your capacitor? It will require some RF isolation, but that shouldn't be hard. 73 Frank W3LPL -- Original message -- ___________________________________________
