Pressure In My Ear While Being Sick

The two days of the 2009 Microwave

As was the custom many years now, even this' year, this weekend, we held the amateur radio exhibition called "the two days of the microwave." Appointment
special and unique, almost a "full immercion" test, measurement and testing equipment and testing devices (transverter, PA, preamplifiers, filters, antennas, etc.., Etc. ....) and everything that makes microwave ! The measuring range starts from 1 GHz to rise, this choice was dictated it would take away space and / or overlapping with the Terni symposium dedicated to the V / UHF even though the spirit of 2 days differs from Terni to the 'non-competitive aspect of the event but the sheer technical meeting aimed at verifying and finalizing the arrangements in the OM participants.

The ability to have professional tools, spectrum analyzers, noise figure meters, frequency synthesized microwave generators, sweep, network ... maybe up to 47 GHz, it is not something every day and accessible to all the microwave! For this it is necessary, at least once a 'year (as the precepts of the church ...) to verify their results, often achieved with more or less empirical methods, with those measured by the most reliable and accurate. Then, it follows that all the group of microwave Ancona (as someone called them years ago, bringing the greetings ...) went to Bagnara di Romagna with its "prototype" (someone finished during the night) in the arm to make measurements, add something to , to revise, improve ... always interesting and useful.

Describe the various tests, devices, measures would be too long a speech, I refer you to the photos on 'Picasa .

Burping A Lot After Having The Flu

"work" on Beacon I6XCK / B

Today we (and iw6atu i6xck) put in his natural bandpass filter in the housing guide, see previous post, that is serious about driving beacon i6xck / b Paterno.
From this afternoon's in the air!
With 'even when we moved (slightly) the' location of 'antenna (qTf 355 °) and frequency (QRG 10,368, 830 MHz).

filter ...

This morning I made a "jump" from Jupiter (IK6EFN) to check the "Bandwidth" (which is not a band in motion ...) some filters to bring recovery in frequency around 10 GHz RF filter needs of a microwave was necessary, the beacon I6XCK / B, to mitigate hypothetical interference on adjacent frequencies in use to other users. E 'was still a good technical exercise and the results were, in our opinion, more than good, below the graph of the filter and the sight of all the instruments used.

The Difference Between Flea Bites And Scabies

fox hunting

Quest 'today, in a wonderful frame (as they say those who speak well) of the Municipal Park of the Citadel of Ancona was held by the now familiar expression of "fox hunting" organized by the ARI Ancona. Of course, no dogs or horses shall velvet jackets and horn (in terms of musical instrument) nor shall the foxes, but simply small transmitters in VHF (or UHF) home-made (home made) hidden in the middle and the green hordes (no exaggeration) of amateurs ready to find them! OM teams ready for the hunt were different and all are motivated and ready to challenge ...
In this edition, along with amateurs, sided with some pupils from the elementary school where I6GFX, Gianfranco, had brought the verb Radio ... even if you were expecting a larger presence.
The "race" was "difficult" because of the muggy day, especially ... and also the number of "turns" (read: years) is particularly high, of course OM, but at the same time fun and instructive! Between a fox el 'other (just 10 ... are many!) Has become the' lunch time and as often happens, the event was concluded at a local restaurant with lots of noodles, roast, trimmings, wine, fresh coffee, etc.. etc ... and toast!

Fair Marzaglia

Marzaglia That's, of all the fairs for Radio Amateurs, is certainly the most interesting and decidedly different from all others. The formula certainly guessed, is that the exchange between individuals, are not allowed companies (or almost, at least at the official level), there is no entrance fee (and these days is no small thing ...) but mostly this is only and exclusively, radio-electronic equipment. Participation, needless to say, is extremely large space available is large, a 'whole camp that twice the' year turns into a huge fair. L 'organization is managed by ARI Modena, click here to learn more!
As always in these situations you have the opportunity to meet lots of friends and fellow radio amateurs who come from disparate parts of the peninsula. I met friends in the microwave zone 3, giving us an appointment for two days and friends of Pescara where I ripped a promise to participate in the contest ATV in June ... and many others on the list would be long.
I've brought along your camera ... you need to be satisfied with pictures of the phone! The pictures are in the afternoon when the crowd had thinned out or he would have only seen a lot of people ...

Who Has Brent Everett Bottom With

I always test on this day! What then is not to say that we are missing some Friday ...! Today
with France, we spent a day "full immersion" to re-test the equipment after the trauma last weekend. Despite all this it seems that the damage was kept to a minimum, the first test apparatus have responded well in terms of both sensitivity and power, perhaps the 'single device with some damage was the' only thing trade, namely the UHF transceiver serves as the IF. We proceeded to replace it with a more powerful model. The 'only thing we had to change is the interface system for switching and three RTX Transverter, circuitino a simple but managed to do, however, pull down from the pedestal a saint ... Below
transverter in the tests, measurements and checks on the bank of our lab / station.

Friday Test-Microwave Contest May 2009 -

This weekend we held the second "episode" of the microwave Contest. We chose (and I CVN France) as "location", on this occasion, an alternative compared to the historical cocuzzoletto Paterno. The QTH locator, JN63QN always, but again punched and precisely in Montevarino.
L 'quiet start, good spread, spring temperatures, a few technical glitches ... FT290 the third (after the two last time) with some difettuccio the reception, some minor interference at 5 GHz (a public wi-fi to some tens of meters). But the problems came in the evening when, suddenly, he raised a strong wind has serious difficulty in the stability of our dishes! Both have blown at the end of the parable of the 10GHz France ceded rolling in ' air and landing on the body of his new car ... At this point the sky is obscured (perhaps due to the presence of all those saints that France was recalling ...!!!) and is not nothing left in a hurry to dismantle all the equipment and go home. Of course, once removed all the wind has eased off and left a sunset from the movie!
Even today, Sunday, the wind does not make up his mind to quit in the late morning and we came back in the old location of Paterno. Here, the wind was less, being now the location covered by trees and buildings, but for this fact we can not do great things and then there was the propagazine yesterday ...
Thus, for the first time, we thrown in the towel before the end of the race! Even
of this round of contest there are images, some shots with a special appearance by Stephen (my brother) who has also made available to the telematics support!
