Spiderpole 12m anchoring construction

Скраћена веза: https://pedja.supurovic.net/veza/8741

Spiderpole 12m made by Spiderbeam is very useful for portable ham radio activities. To do the job it must be properly anchored. This pole may be anchored at the bottom (at about height of the first element) which allows it to withstand wind speed of abut 80 km/h, and at 7 meters high using guying lines (as recommended by manufacturer) which allows surviving windows of 120 km/h.

Anchoring at the bottom seems not suitable for portable, as it requires either to have already set strong short pole (fence or something) to attach pole, or dig one into the ground. […]

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

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. […]

Намена радио-аматерских репетитора

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.

WCW2016 – World Castles Weekend in Uzice, Serbia

Скраћена веза: https://pedja.supurovic.net/veza/8404

For this year World Castle Weekend I activated Old fortress in Uzice (WCA YU-00023, JN93VU, WAS ST03) using my call sign YT9TP/P. Again. Activation was not announced, as usual, and served as surprise for fellow hams chasing WCA points. I had great help from Goran YU4RAA who participated in antenna and station setup.

Weather prognosis was not ideal. It was expected to have some showers which reduced our options of station location. Instead of setting it on top of fortress which would provide high point and lot of clear space, and no protection from bad weather, we decided to go safer way and settle at only space that can be used as shelter. […]
