Radiant Barrier Amateur Radio Antenna



conversation at the frequency VHF meeting Alejandro (LW7HT) told me about an article Dani Perez (EA5FV) related to the technique Single-Operator-2-Radio (SO2R) . While already built my driver and I was trying to use it (hopefully uneven) immediately searched and found the article in question (which can be downloaded from this link ). In a very lively and colloquial Dani said right from the beginning that is the technique to be used, what are its limits and she gives some examples of practical use. Then make even the configuration of equipment and antennas. The article is rather old now (2001) and note the recommendations of software and drivers you use, that I have been overcome in the present. But the basic explanation and techniques are still valid. As he describes putting together a controller is relatively simple, but using it is another story. Luckily sets the tone that it is really necessary when you start to roam the average of 70 QSO / hr (3000 + QSO competition) which is where it is used all the time and it is therefore necessary to "break" and do something different to break that barrier. At this point I have no risk of needing it because I am on an average much less than that. But the technique appeals to me, I have the driver on foot and is likely to use it mainly when you have if or whether to participate in ways SO AB (Manchester Mineira WAE soon and later.) The use of SO SB controller is relative, there is interference with the two teams in the same band, but for multiple checks can be a good thing to be attempted (experience will tell). I have very clear that we need huge doses of practice, not just listen to two stations at the same time, and although there is an expectation to understand both is still necessary to abstract from one or the other to copy this "in the other ear ". One thing that struck me is that so SO3R Dani discarded because of its low effectiveness (doing dueling stations would be two and a third "clicking" multipliers simultaneously). Recommended reading, incidentally, is a sign that the search algorithm of Google has significant relevant areas for improvement in searches does not jump easily to key "SO2R" and not jump first when looking for + + "SO2R" + + "EA5FV" specifically .
