DCTL Antenna???
Pete
Has anybody tried the DCTL Antenna described by N5FC?
() It sounds great - small, efficient, resonant, and cheap. I've tried several times over the last few years, most recently yesterday, and never gotten one to work anywhere near as well as the authors claim. Would like to know if anyone has had any success. Pete, NI9N |

Re: NVIS Saturday afternoon test
--- In FT817@y..., "John O. Newell" <jnewell@m...> wrote:
Just a quick follow-up to Keith N1XTK's report on our NVISJohn: I think most of your answers would be answered in Feilder's and Farmer's book "Near Vertical Incidence Skywave Communications -- Theory, Techniques and Validation". I highly recommend it. For example, according to the authors, daytime amateur radio NVIS frequencies are most likely in the 40 metre band during the day and 80 metres at night. At least your daytime experiment seemed to confirm their recommendation (as far as I can recall, they mentioned that amateur NVIS bands could shift to 80 metres daytime and 160 meters nightime when the solar cycle is at or very near the bottom. Again we are talking probabilities and not absolute certainties.) It would have been interesting if you could have continued your experiments on an hourly basis well into the evening with a change in bands to 80 metres after sunset to see the differences. With respect to the one-way communication aspect, it can be reasonably explained by recalling the author's antenna gain versus antenna height diagrams. As I recall, the greatest gain for signal propagation near the vertical is when the dipole is at one quarter wave above ground, while the gain decreases significantly as the dipole gets lower and lower towards the ground. Therefore, it is not surprising that the station with the dipole would be better heard because, as I recall from the other posting, it's apex was at about 35 feet, close enough for government work to be at a quarter wave length from the ground. On the other hand, the Jelinek antenna, constructed in the same manner as a US Army antenna, is only 15 feet from the ground, resulting in a significant loss in recieved signal power at the receiving end. Again, your observations on this point were not all that out of line with the recommendations of the authors. Moreover, as I recall, the authors base their observations on using transmitters in the 20 watts range. As a result, if you were using barefoot FT-817s, even less signal would be present at the received location. I think your observations were worthwhile, and if you don't mind, I will use it as practical examples in some of my NVIS presentations in the Ottawa area. For that matter, I would like to construct a couple of 40 meter NVIS antennas - a dipole at about 35 feet above the ground, and an inverted Vee, with the apex at 35 feet and a counter poise. It might be worthwhile to see if we can communicate with each other using either or both of these configurations. Are you going to experiment again? 73 Jim, VE3XJ |

Re: So 92.64% of you are Nomads
In response to David Henn's reply, I think there needs to be
clarification. With respect to David's assertions that there is no ambiguity, ("The Middle East is a defined area, I would never connect it with Asia.") The Encyclopedia Britannica (EB) would disagree with his assertions. For example the EB website defines the location of the Middle East as "the lands around the southern and eastern shores of the Mediterranean Sea, extending from Morocco to the Arabian Peninsula and Iran and sometimes beyond." For even greater certainty, it lists most of the countries as follows: "... the term Middle East was given to the British military command in Egypt. Thus defined, the Middle East consisted of the states or territories of Turkey, Cyprus, Syria, Lebanon, Iraq, Iran, Palestine (now Israel), Jordan, Egypt, The Sudan, Libya, and the various states of Arabia proper (Saudi Arabia, Kuwait, Yemen, Oman, Bahrain, Qatar, and the Trucial States, or Trucial Oman [now United Arab Emirates]." The EB goes onto say that other countries are also included from as far east as Lybia and west to Pakistan depending on circumstances. It is worthy to note that the EB supports my original missive to the group - the term "Middle East" includes countries from Asia and Africa. In fact, it could be argued that Middle East could be found in Europe, because Turkish territory in both Asia and Europe. (I hadn't realized this myself until I had drafted this reply.) As a result, I would find it difficult to agree with the notion that the area of the Middle East is defined. Lastly, I do not dispute that Belize is located in Central America. However, it is accepted that Central America is located within the continent of North America. The EB defines North America as follows: "North America is bounded on the north by the Arctic Ocean, on the east by the North Atlantic Ocean, on the south by the Caribbean Sea, and on the west by the North Pacific Ocean. To the northeast, Greenland is separated from Iceland by the Denmark Strait, and to the northwest, Alaska is separated from the Asian mainland by the much narrower Bering Strait; North America's only land connection is to South America at the narrow Isthmus of Panama." Belize, by definition, is located in North America. Furthermore, any confirmation of amateur radio contacts with Belize for the ARRL's Worked All Continents awards are classified as North America. As a result, listing Central America with South America instead of North Amterican is an error. I would be pleased if David would be kind enough to list the standard references so that their information can be compared to that of the EB. I am more than happy to take this to simplex now. 73 Jim, VE3XJ --- In FT817@y..., "David Henn" <drhenn@y...> wrote: --- In FT817@y..., ve3xj@r... wrote:splitDavid:Hello Jim,, "EMEA" into distinct areas for better granularity.

6m Whip
Simon Brown
Hi All,
I ordered a FT-817 today, having been QRT since 1983/1984. I was GD4ELI, am now HB9DRV. Do 6m 1/4 wave whips exist for the car? When I was last active 6m wasn't allocated (I think). I'm off to the Friedrichshaven fest at the end of June, maybe I'll find one there, but would like to know whether I'm wasting my time. What do you all use for 6m while mobile?

Running the SGC2020 and 237 from the same source leads to problems when voltage dips on voice peaks. (From a 7 amp Pyramid PS). When this occurs, the 237 loses tune and relays start clattering. I figure a 7ah cell for the 237 and small, maybe 1.2ah for the tuner would be realistic. Thanks for the info also Bonnie. CU on HFpack..... 73 Nick WB4SQI |
