IR0UCA: DMR Repeater
- Visite: 214
E' stato messo in operatività un ripetitore DMR su 430.400 +5MHz con callsign IR0UCA. E' stata utilizzata una base station Kairos della Radio Activity Srl. La scelta è ricaduta su questo hardware perchè è basato su Linux O.S., ha una interfaccia utente Web e molte altre funzionalità non presenti su altri sistemi similari.
KAIROS is a multi-protocol repeater that implements all mo-demodulation and filtering processes via software by a Digital Signal Processor (DSP), following the “soft radio” concept. This technique provides repeatability, perfect matching among repeaters, and can handle different types of protocols, depending on the incoming type of signal.
It is designed for infrastructure applications where radio frequency pollution is a well-known issue: KAIROS’ excellent resistance to adjacent channels and blocking, its noiseless transmitter, and soft diversity reception reduce in-field problems, thus providing excellent coverage and clean communications.

E' stata sostituita con una telecamera HIKVISION DS-2CD2T42WD-I5
It's possible to view the images on Wundercam.
A new project is started: one weather cam stand-alone with an XiaoMi YI action camera. This action camera has a Linux inside, fully customizable, wifi connection, telnet connection possibility. With some simple mods can be used as weather cam.
Now is in test stage, it has been placed outside with its waterproof case.
IR0UGN-8 PSKmail server

IR0UGN-8 is a PSKmail server on 10.148MHz (10.147 Dial). PSKmail is a narrow band arq system for use by amateur radio hams via short wave (HF) communication. It does not use a special controller, you just need a computer with a sound card.
Pskmail is predestined for emergency communications. Even if the local internet is down, the long range on HF guarantees a connection to the internet. And it is child's play to set up an ad hoc server.
IR0UGN-1 PSAT-ISS iGate: active

To be active on APRS like an iGate for the ISS (International Space Station) and PSAT (ParkinsonSat), I moved the IR0UGN-1 on a TS-480HX in order to leave the TS-2000 for tracking the ISS.
It's possible to find latest news about the ISS on the page ISSFunClub and it's possible to find latest ham radio contacts on Ariss.

KWOS is participating to the Microsferics project! Look the result on the Real Time Weather page.
Microsferics Lightning Detection Network, MicroLDN, is a low cost, high accuracy experimental lightning detection network currently operating in parts of Europe and North America.
By using off-the-shelf electronic components and custom designed signal amplifier electronics we created a GPS disciplined time-stamping device for the Boltek range of lightning detectors, making them capable of networked lightning locating using the signal Arrival Time Difference locating method.
