audio-kenwood-baofeng-samsung-s3-trrx

Samsung SIII uses four pin 3.5 mm TRRX connector that differs than standard TRRX.

This cable can be used for APRS/Packet Radio. Most popular program for this purpose is APRSDroid. ALso can be used for Echolink, audio recordings, or similar usage.

You have to adjust volume output on both Samsung phone and radio to avoid distortions. Cell phone cannot control PTT of radio so you have to turn on VOX on radio to enable triggering TX when signal should be transmitted. […]

Portabl antena od ribolovačkog štapa

Skraćena veza: http://pedja.supurovic.net/veza/7644

portabl vertikalna antenaŠtap je od fiberglasa, dug je šest metara, a težak svega nekoliko stotina grama. Dovoljno je čvrst da se na njega može okačiti vertikalna antena pa i dipol. Sklopljen štap je dug 110 centimetara tako da je prihvatljiv da se nosi na rancu.

Antena je klasičan monoband dipol za 14 MHz, samo je monitran tako da se vrući krak okači na vrh štapa i visi kao uspravna antena, a drugi krak se postavi pod uglom od 45 stepeni kao jedan radijal i antena praktično radi kao GP sa jednim radijalom. Antena je umerena i SWR je 1:1. […]

Kakvih sve likova ima (Danijel Miletić, „radio-amater“, Republika Srpska)

Skraćena veza: http://pedja.supurovic.net/veza/7632

Primetim ja danas da je na grupi BiH radio-amatera na Fejsbuku  objavljen jedan članak koji je bukvalno prekopiran sa mog bloga, a potpisao ga je Danijel Miletić (Bijeljina, Republika Srpska) kao autor. On inače i administrira tu grupu.

Ostavim komentar u koji stavim link na članak na mom blogu odakle je tekst uzet. Nepun minut kasnije izbačen sam iz te grupe.

Pošaljem Miletiću privatnu poruku da pitam što sam banovan i dobijem odgoor:

Ispade da sam ja navodno negde nekoga nagovarao da ga banuje (što nije istina, niti znam gde je banovan, niti sam igde tražio da  […]

WCW2014 – World Castles Weekend in Uzice, Serbia

Skraćena veza: http://pedja.supurovic.net/veza/7592

It was just several days before this year world Castle Weekend that I decided to participate by activating one of the fortresses in surroundings of my hometown Užice. Actually, I was targeted to activate YU-0030, Fortress of Solotnik, as it was never activated before and thus should be more interesting for WCA hunters.

As I still did not have all necessary equipment and tools I asked for a help of Milan YU1ZZ. As experienced contester he was up to the task, ready to improvise if necessary. One short phone call settled it down. Milan is primarily high  […]

W6CCP – The King of Impoliteness

Skraćena veza: http://pedja.supurovic.net/veza/7530

Today just past 17:00 UTC at 14214 kHz I witnessed behavior of  ham radio operator W6CCP that was as rude as it could get.

Saddiq A41KJ was on the frequency calling CQ, and had big pile-up from European stations. He was called all over but handling situation nicely and getting through the list of stations calling him.

Then, out from nowhere, W6CCP came out, obviously with high power, screaming on top of all other callers for Saddiq to turn to long pass to North America. He was so powerful that he out-called all stations in pile-up. He  […]

Remote controller for antenna switch in a stack

As I live in apartment building I have apparent problem with setting up ham radio antenna. The obvious place to set up antenna was the roof as it  is easily accessible. Due to small space and me not wanting to make mess of a wires, I decided to use compromise vertical multiband. A friend had spare DunaX-GPN4B (40, 20, 15 and 10m) so it was obvious choice. I had to put down about 30m of coax cable to my apartment, and soon I was in the air.

Not for  […]
