Gary et. al. We used that configuration over radials on ground on Curacao in the mid-1990's from the end of the resort near what is now PJ2T. It is really closer to 5/16 wl, and with half vertical an
Gentlemen: Tim writes very well below. However, I have had 45 or more FT8 emails and I truly think we are airing the same laundry many times. Steve Ireland did raise a very good point......but.... Wh
Jerry, et. al., I didn't have the problems from my own installation, but I used to live about 1/2 mile from an AM 930 station and there would be a 2nd harmonic spur at 1860 and a mixer spur of 2 x 14
Hi Jerry & Topbanders, Doing the math from the info below: AM 890 x 2 = 1780 KHz + 1730 KHz = 3510 <- - your 80 meter birdie. I hope this makes sense and helps solve the puzzle. As I noted before, it
Ladies and Gentlemen, Isn't it time to just stop the discussion?? 73, George, K8GG _________________ Topband Reflector Archives - http://www.contesting.com/_topband
Hi Gary & fellow Topbanders... It seems that Gary's 129 foot wire may be actually 133 to 136 feet long, depending on radials and ground conditions and whether the wire is bare or insulated. I did a q
Martin, et. al., For temporary work from Curacao, we taped beverage wire to the asphalt pavement for an E-W beverage that worked OK (we did not model it), and allowed us to QSO Central American stati
E31A was workable until about 0405Z, then faded quickly in Michigan. Heard Tim's QSO and many other US 1's and 2's and some 3's, and some others in MS, TX, IN, OH, IL, MI. Also some I's, an SP5, an R
Jeff, Et. Al., Rather than wrap the wire around the insulator opening or itself, how about a "split bolt" wire clamp with the saddle on the tension side? A good "mechanical knot". I can take photo of
Roger, Et. Al., On the contrary, Sunday morning in the CQWW 160 CW there was a peak observed from Michigan. A very weak EI4??? called me about 0730Z without a QSO. Then G3PQA popped up solid and we m
Fellow Topbanders: Sometimes I hear a DX station calling CQ and no one else calling. I think it is good practice to let them know they are getting out, no matter how many times I have logged them bef
Hi All, Since Roger, G3YRO, suggested that Wednesday night was a good time for activity, and I happened to be at a radio, I turned on 160 and found some good strong signals: G3YRO 0102Z, OK1CW 0132Z,
Good point Frank, We had similar problems at a Caribbean Island ham station and used a pennant aimed at Europe with the back end pointed at the TX antenna about 100 meters away. Worked well that way.
Jim, et. al., One can also use a spring loaded wide spaced solenoid contactor to get more voltage gap if switching to the 80 meter position. One of the problems is building a 1500 watt tuned tank coi
Hi All, I was discussing this thread with a microwave engineer on 75 meters this morning and he reminded me that I had AM RF in my RX antennas at my previous QTH. So much that I used Hi-Pass filters
Hi Ash, Hello All, As a long time Beverage user, I can definitely say that the performance can be enhanced by having good ground at the termination resistor end of a beverage. Operating from Aruba in
Hi All, A couple of thoughts: I used an aluminum powder filled version of Permatex or similar anti-seize compound the last time I put up an aluminum tower (Heights or Universal). No continuity proble
Filipe: In the USA and Canada: 1810, 1820, 1830, 1840, 1850, 1860, 1870, 1880, 1890, and every 10 KHz through 2000 KHz. I missed some Eastern Europeans because they TX on 1870 in CQWW CW Contest and
Hi All, Frank is correct. We originally designed the Battle Creek Special to use 16 radials 1/4 wavelength long on 160 (about 135 ft each) and then found that 32 radials 1/8 wavelength long (about 70
Iain, Etc., Some years ago I operated 160 and 80 from PJ4-Bonaire. W8UVZ, KD9SV and I used a single pennant antenna aimed at Europe with good results. Bottom about 6 feet above ground, 14 feet of ver
