Скраћена веза: https://pedja.supurovic.net/veza/8901

Beginning of October (1st to 16th) is time of the year when amateur radio operators from Užice participate in celebration of Užice City Day by activating Užice Award.

Užice is old city. It’s first mention in written document is in document found in Ragusan archives, dated October 9th, 1329, almost 700 years ago.  However, city is much older, it was on map of Roman Empire, and archeology found evidence of settlements as early as Neolithic age.

As award manager I have to give good example by participating in award activation. For me that means going portable as I cannot practice ham radio at my home. […]

Better Syncing Windows With Atomic Time Server

Скраћена веза: https://pedja.supurovic.net/veza/8659

You may have need to have accurate time on your Windows PC. Windows already does have support for network time server synchronization and with recent versions ti should be set and turned on by default meaning if PC has access to Internet it will synchronize its internal clock with some of the world atomic clocks.

However, it might be good enough as synchronization is set to rather infrequent time periods, one day or even whole week. For some purposes it is needed to have clock synchronized more frequently. I need it for working Amateur Radio digital modes.

There are number of third party applications that can be installed on Windows PC as SysTray applications or services and allow more precise time synchronization. […]

Radio Amateurs in War

Скраћена веза: https://pedja.supurovic.net/veza/8628

Symbol of defense of Yugoslav people became global symbol of resistance to NATO and USA terror all over the World.

March 24th. Year 1999. The very end of the 20th Century. With the nightfall strange sounds were heard in the sky and at 19:45 – explosions. Bomb fell on Yugoslavia, small sovereign country in Central Europe.

One word is on everyone mind – WAR!

Yugoslavia was attacked by NATO military alliance led by United States of America, the country Yugoslav people always considered as one of the best friends. At first, people were fighting mixed feelings caused by unjustly accusations, vicious attacks and betrayal of considered friendly and ally countries and disbelieve that what happens is at all possible as that was act against international law. […]

IARU REGION 1 – ПРИНЦИПИ ПЛАНИРАЊА ВХФ, УХФ И МИКРОТАЛАСНИХ ОПСЕГА

ФМ репетитори су намењени као комуникациони сервис мобилним радио/аматерским станицама (укључујући и ручне станице). По потреби, могу бити инсталирани и за побољшање доступности станица у планинским подручјима.

Они нису намењени да омогућују DX везе, стога њихов домет у уобичајеним условима пропагација треба да буде ограничен.

Број инсталираних репетиторских станица треба да буде одређен према
– потребама за регионално покривање
– очекиваном броју корисника

Не треба да буде устаљено да се ФМ репетитори употребљавају као канали за ћаскање за фиксне станице. То се коси са њиховом наменом.

Baofeng LiIon charger modification

My idea was to be able to use this to charge Baofeng radio in various power conditions including in my car and this voltage was a problem. I noticed comments that charger should not be connected to higher voltage than 10 Volts. So I modded charger to fit higher voltage. baofeng-charger-mod

HamClock

Скраћена веза: https://pedja.supurovic.net/veza/8292

hamclockHamClock is quite simple Android application for amateur radio operators. It’s purpose is to help hams working portable.

Operating portable usually means carrying light equipment, especially if everything has to be carried in backpack, on foot or on bicycle.

In most of my portable work I do not carry laptop with me. It is not that I do not need it, but I usually work in the open, and it is really hard to read my laptop’s display when in sunlight, and even in light shade.

Therefore I am used to carry paper log of pocket size and do logging by hand. […]
