If the rotator cable is laced to the tower (most prefer the inside of a tower leg) it will be at the same potential as the tower all the way along the height, thanks to capacitance between the cable(s) and the tower.

Would that > differentiate between "dead band" and "lack of activity"? Yes. I always check RBN to see if my CQ is being spotted in EU or VK or JA etc. However, a few comments about the RBN network. For 9 years I have been running my RBN skimmer node on the RBN network and have noticed that I will only decode a small fraction of what I can actually copy with my radio and ears. First of all, my main skimmer SDR radio is using a 30m loop antenna, while my real radio is using diversity RX with the 9 circle array and phased Beverages. This is not uncommon with many other skimmers on the RBN network that may use compromise, and omni-directional antennas. Often the trans-polar DX can be very weak, and just bubbling at the noise level which is simply not enough for my CW skimmer to decode together with the CQ. However, when my skimmer IS decoding and reporting EU DX to the RBN, then the band must be really open. Therefore, the reciprocal of this is equally true. Just because my CQ is not being decoded in EU is not proof that the band is closed. But on those nights when I am hitting many of the EU skimmers, then clearly things are good! I stream all RBN spots through VE7CC into my logging program, band map and onto the Flex display, but to get a EU or NA summary of whats going on, the main RBN network webpage is great. In case you haven't used the "filters function" on the RBN network page, here are some tricks that I find very handy to get a quick snapshot of whats happening. Just looking at all spots on 160m is not very helpful because with lots of activity, detail is lost. Here are some example filters: ALL EU being spotted by NA skimmers: http://www.reversebeacon.net/dxsd1/dxsd1.php?f=3896 <http://www.reversebeacon.net/dxsd1/dxsd1.php?f=3896> This one is handy when I CQ only VE DX being spotted only by EU: http://www.reversebeacon.net/dxsd1/dxsd1.php?f=81972 <http://www.reversebeacon.net/dxsd1/dxsd1.php?f=81972> OR are any VE CQs being copied in EU on 160: http://www.reversebeacon.net/dxsd1/dxsd1.php?f=14728 <http://www.reversebeacon.net/dxsd1/dxsd1.php?f=14728> (You can also show up to 100 spots to give more history .drop down window at right) Make your own .. You can make any filter you want based on: DX country (zone, continent etc) and SPOTTER (based on country, zone, continent etc.) and band. Just go to the top banner and select: DX spots > create your own filter. Also, don't forget that 160m is the band of QSB and patience is essential. Just because you don't copy a DX spot, it may take 10 min of listening before the short QSB peak might make him copiable .for 20 or 30 seconds!! Yes this aint the 20m band.

März 2020 13:52 To: topband@contesting.com Subject: Topband: NVIS Antenna Well I've said it dozens of times before . . . but I have used a horizontal halfwave Dipole (at about 50ft) for working DX on 160m for the past 50 years ! (and that's at 6 different QTHs) Not only do I work all over the world, but I know my signal often compares pretty well with other Gs using good verticals . . . and I have no problem getting through the pile-ups working the various DX-peditions. How is this possible? Well in my opinion it's because DX propagation on 160m ISN'T like 80m (where it IS nearly all low angle, so you MUST have a good vertical to work DX effectively) Based on the hundreds of comparison QSOs I've had over the decades, I figure that on 160m, propagation MUST be fairly high angle a lot of the time, presumably because of inter-layer reflections or ducting. Most of the "experts" who have written books about Low-band DX-ing have made the assumption that 160m is just like 80m . . . which in my experience it clearly isn't ! The only other factor I DO think is that if you have a low dipole on 160m but DON'T have any radials or anything underneath it, it probably radiates more low angle than computer-modelling software would suggest. I believe the errors occur on 160m because it can't properly forecast the effect of the REAL WORLD ground when the antenna is a fraction of a wavelength above it.

Lets say -- for the purpose of discussion -- that the two towers are in a north-south line. If you point the 40M Yagi East or West (perhaps +/- 45 degrees), the top of the T-vertical will be either below the Yagi or off to its side. If its less than 70 feet below the Yagi, the T-top will significantly degrade the performance of the 40M Yagi.

I think two design issues help to avoid pattern distortion to nearby HF Yagis. First, as Frank suggested, keep the length of the horizontal T wire non-resonant on any given band, including non-harmonically related bands like 30m. It's not necessary to select a T top wire length that results in resonance at the base feed, at least with a single omni antenna. Secondly, there's a difference in interaction between a T that's installed broadside to a Yagi versus one that's installed perpendicular off the end of a Yagi. For example, If a T is installed between two towers that are spaced 150 ft apart and a 40m Yagi is atop one of the towers, the T top wire is never broadside to the Yagi. It's looking straight down a piece of wire. It's no different than a Yagi director that's rotated 90 degrees to the driven and reflector elements. In fact, an existing Yagi design file could be modeled that way only with a rotational change to the director's Cartesian coordinates and a change in distance from the DE. No doubt modeling will still show some interaction but what remains should be cured with an optimum, non-resonant director length.

Re: Topband: New Modes, Systems, etc
If my 160m receive would be as bad as with any web sdr I would not contest on that band. Which web sdr is used from Eastern Europe? 73 Peter -Original Message- From: Topband [mailto:topband-bounces+dj7ww=t-online...@contesting.com] On Behalf Of uy0zg Serious problems for topband are the use of WEB.SDR.
