The logger competitions

Having decided to shelve AATest due to problems in maintaining the integrity of the data in a reliable, consistent lack of support and non-existent documentation begin what promises to go be a substantial learning curve to get a handle on some familiarity with the program that provides free N1MM . Given the wealth of functions and elements to configure guess it takes an appreciable time to take advantage in some depth what it can offer. Just a cursory reading shows that the scope of the program is equally profound for CW, SSB and digital modes (RTTY, PSK, etc). The documentation looks stunning with over 400 pages with all kinds of functions, macros, tips and suggested settings. As is well established in several parts of the features offered are so specialized that end advising " .... if you can not serve this function to leave it as it is !!... ."

I am slowly setting up a basic configuration that when you return to Argentina on my machine can display radio testing different combinations of macros and settings database. However, the party will most likely have to work with the equipment interface and that I can not do until you are back.

For now I know that there will be conflict in the use of CAT as N1MM provides its own services for remote control of equipment, but does not provide a way to integrate external programs to process signals (such as filters in my case ) or tuned via an interface to external waterfall. To keep doing that with the combination CwGet + OmniRig can not let N1MM take control of the respective serial ports. So I need 2 ports two separate series for CAT SO2R configuration under the control OmniRig and other 2 ports for two separate series under the control of manipulators N1MM. Another alternative is to manipulate LPT port (for which I have to change the keyer interface) as in this case with a single port can control two computers. Curiously not provide the possibility to control the manipulation that goes radio by pin serial port and if done with a pin LPT port. N1MM

also provides support for tuning by OmniRig therefore can not share ports with the series. This has further negative aspect that will not help all the provisions that have the software to control N1MM tuning of the equipment involved, especially in modes assisted "from the data stream coming from the cluster.

The alternative to using 4 serial ports and 3 serial ports plus an LPT port can be to use a splitter serial port as virtual serial port provided by the company Eterlogic (vspeed) but will have to test carefully possible interactions between such thing walking at the same time trying to control the same hardware resources.

A small bonus, surprisingly, was found in the documentation of N1MM a reference to a program I wrote some time ago called TelMgr whose purpose was present as a gateway to telnet to an AGW Packet Engine ; long that program is in legacy mode (ie without active support and new versions). But it has been stable for a long time and its purpose is so dimensioned that can continue to function indefinitely until some change in the operating system introduced some change (such as Microsoft usually does) that causes that no longer work. Figure under the authorship of my old license (LU7DID) but still can be downloaded from my website at qsl.net .

going to be important to see how you can evaluate how it works once it's set at the station and all the hardware already deployed settings, experience in the ARRL DX shows that one can not expect the competition to do so. But then there are contests in which thinking involved at my station until May (the first date of Argentine HF and CQ WPX CW), before that is the CQ WPX in which it appears that will participate in an M / M from LQ5H or Russian DX that has no category that catches my attention (AB Mixed QRP only). Ingeniarmelas so I'll have to try everything in normal QSO. It is a platform worthy of respect it deserves appreciation to those who have taken so much work to put at our disposal.

N1MM IARU HF Championship (Final Scores)

In the post I made Claudio Fernandez (LU7DW) Forum LU-CG displayed the final scores of the contests in its 2010 edition. In the SO CW QRP category for South America, the results are SO CW QRP:
LU1DCB (op LU6DO) 1st SA (120M47 23124)
LU8EHR the 2nd SA (27M19 1045)
LU7HZ 3rd SA (15M10 550) Asking
Claudio then I confirmed that the score was confirmed 15M10, which multipliers is similar to what is claimed but half (!!). QSO
All of the scores look details can be found at the site of the ARRL to analyze the degree of detail needed.
Having been my first international competition and limited participation any outcome is good, but I am struck by the difference between claimed and recognized (what can produce such a difference? participants who did not send the return? "wrong number of series taken?).
One issue that continues to draw attention to me, and which does not yet heard any convincing explanation, it is because it takes so long to publish the results of the competitions. Once you close the shipment of returns, and assuming that the majority are submitted in electronic format is a matter of hours to get the scores with all the crosses and checks imaginable. Even assuming volunteer exercised at the discretion of "the best "in the final editing and publication of the results have to wait between 6 months and 1 year (in some cases until the next edition of the competition, in some cases even later) does not make much sense. From the point of view of a learning process is quite counterproductive, if one has a weakness when he learns competitive and committed several times.

comparing the QSO / multiple claims with the given. The pattern that seems to appear is a massive loss points of contacts on 10 meters (?) where 3 / 4 of the items claimed were not for the reason it was granted. In 40 meters was something like half. At 20 and 15 meters there was no this problem directly.

Looking more closely at the database with scores meeting recognized that almost 2 / 3 corresponds to the missing stations are not recognized scoring (Could not they have sent form? would not be participating in this contest ?), While the remaining 1 / 3 if you are so I can only speculate that the problem was that or took bad exchange, or I took it wrong or I gave as valid contact and they do not (being my first competition I do not discard any of the three as a possible cause.)

With a learning perspective to the next where he won the contest in the category SO QRP was HA8BE ( 914M227 588838 !!!), I find it hard to imagine how such a score to give .... only in No. 42 appears LU1DCB as the first in SA, 77 LU8EHR and I appear in 87 (three colleagues from Brazil that made me the huge gauchada of submit forms with few contacts to avoid the uncomfortable position of being last ☺).

More interesting is to observe, in view of participation in planning the 2011 edition, as is the use of bands. For stations SA (all categories) 72% of the QSO took place on 40 and 20 meters, whereas 15 meters is also 89%, meaning that for stations in SA the rest of the bands is irrelevant. For example 10 meters only captures 3% of all contacts.

If I restrict the analysis to my own category, 70% of all QSO took place on 15 meters while 92% in 15 and 20 meters, 40 and 10 meters were relatively irrelevant with just under 4% each, the rest of the bands does not exist in QRP. When it comes up a bit multipliers importance of 10 and 40 meters who happen to accumulate nearly 16% of the many achievements while Lowering the contribution of 15 and 20 meters.

In the original analysis of participation it had found 40 meters QRP at that time was not a sustainable source of QSO, even considering that is my first participation exclusively Search & Pounce (S & P).

strategy for the forthcoming IARU 2011 is clearly having a good chance to run in 15 and 20 meters and using the building (I hope to have well-developed and practiced for then) SO2R achieve adequate S & P 10 and 40 meters , the target score is obtained by LU1DCB 120M47 this year or more.

The end result of this issue is thus a story, my first international competition and with the participation of only a few hours, all gain.

HF Propagation (Tutorial NM7M)

's excellent tutorial HF propagation of Dr. Bob Brown (NM7M, SK) scored by Thierry (ON4SKY) can be followed in fairly plain language (although English ) explanation of how the basic mechanisms of ionospheric propagation as predicted. Then it explores the major stressors that although not fully be predicted given the chaotic nature of the phenomena involved may operate with corrections to be taken into account. The material was written some time ago (it shows because they provide referrals to what happened several solar cycles ago) and have annotations made by Thierry latest, yet most of the material already has some old but is updated in that respect universal phenomena for which the state of science has not made significant progress since the material was written. One of the interesting findings that the material expressed is that once you understand the phenomena VOACAP program has most of them into account what is a resource that should be considered when making any predictions propagation, a link to a Web online version of this program can be found useful links between this blog. During the reading, quite enjoyable considering the potential dryness of subject matter, maintaining the foot in the field of applications for radio, DX and contests although not so many references are appealing to math and literature. A pdf version of this material can also be downloaded from here .

Toy Cute (and surprising) with LM555

Sencillito circuits have a broad appeal. Can be assembled in a "little bit" out of one, you can use for a beginner to assemble more or less on their first project insurance and walk .... and above all things almost always are trivial enough to not pay much attention.

I say usually because every once in a while a very simple circuit but whose operation is not as trivial or obvious, and in fact takes us by surprise with his guard down because we had happened to us face to "that side "to achieve the same result.

I refer to the tests with a design released by Pedro Ghiano (LU3HGP) although originally appeared in the forum GQRP which uses the timeless and very versatile LM555 integrated but as .... AM receiver.

to me at least it is new, and once I read the explanation of its operation is simple and intuitive ...... one is always looking to make an AM receiver with a 555. RF signal, presumably intense as you would with a broadcasting or a sign of good intensity, is tuned by the set of L +100 pF. It produces the shot in advance or delay the natural frequency given by the set R of 555 +0.01 uF pace of audio frequency. The resulting signal is pulse modulated audio compoennte rescue the original signal. Simple, but not first occur to us as a solution. Perhaps the proposed design for the original article can be improved a bit (ie make a ferrite coil Spica radio to make it smaller, or make the variable capacitor a polyvarycon). But certainly Simplite circuit that can provide the basis for a fun afternoon of construction or starting point for a would-be "master craftsman welder ." Recommended.
