Kairos Multi-protocol Soft DSP Radio Dual-mode Digital/Analog & IP Net

KAIROS is a multi-protocol transceiver/repeater that implements all mod-demodulation and filtering processes via Software by a DSP (Digital Signal Processor), following the “soft radio” concept. Dual-mode analog and digital modulation – IP Multicast & Simulcast – Soft Diversity vectorial treatment of two or more incoming signals – RF linking in DMR and analogue modes – SIP and AMBE +2 Gateway & SIP/RTP-IP network for wide range applications & utilityes!

Radio-Activity-Kairos-rear-1

It allows to manage multiple protocols at the same time to perform, for es., a dual mode in real time, according to the incoming radio (or IP) signals. (soft & hardware platforms is based on a Linux O.S. core). KAIROS Series ETSI / FCC  / CE certified – Designed and manufactured in Italy by  Radio Activity Srl – 20128 Milano IT.

Kairos-front-rear-combi

KAIROS, thanks to the “soft radio” designin, approaches this problem, with the same techniques adopted in the most diffused digital communication systems like GSM, GPRS, WiMAX, LTE etc. – It is equipped of 2 coherent indipendent receivers that, connecting then to 2 different antennas, realizes a “soft space diversity” reciving system. – When operates in digital, KAIROS manages the 4FSK modulation, it is the standard mod for DMR & P25, and can also manage, on request, the GMSK constellation and many generic FSK standards like the POCSAG groups.

built-in_Sig&Prot

The KAIROS rtx is dual mode analog/digital with the automatic switch between the Analog / DMR services. – The old FM rtx may operate with the new digital one through the same network.
KAIROS can run a “DMR Gateway” agent to interface Analog and DMR radio systems to several external networks. – The DMR Gateway Agent traslates Voice (full duplex audio stream from/to) and Data streams. (this runs in the Kairos engine without the need of external PC) [Note] (More info: …see the official data of Radio Activity pdf)

italiano Come si potrà leggere dal link qui sotto, IW7DZR, Giacomo e IW0RED, Marco dell’Associazione CISAR stanno già provando con test applicativi apparati KAIROS UHF nel campo radioamatoriale. – In digitale il DSP incorpora e gestisce mod-demod 4FSK per modi DMR e P25 e in dual-mode anche FM analogica – Kairos supporta reti Multicast e Simulcast per realizzare reti Multisite tipo professionale. – Il software fornito gestisce anche un ricevitore in “diversity” con due antenne per il trattamento vettoriale di più segnali in ricezione. – Fa parte del gruppo test anche Artem, R3ABM,  che ha elaborato il software CronosAgent  per applicarlo sotto BM (BrandMeister) !! Attendiamo altre news.

DV4mini Hotspot: a link with a simplex frequency (UHF) and a repeater through the Internet.

DV4mini Hotspot for the 70 cm band and can use it with a D-STAR or DMR or C4FM * transceivers – The DV4mini is a very small but also very capable USB Stick that can expand any PC into a Hotspot for the D-STAR and DMR modes (C4FM * Fusion is in development) – (trial beta ver. 18.8 or later uncheck “C4FM Gateway” only DN & VW mode) – Please read official data and the User manual! (link below)

DV4mini-PC-01

DV4mini  allows linking with DCS, XRF and REF refectors for D-STAR as well s DMR refectors (trial beta ver. 18.8 or later unckeck C4FM Gateway!). With the DV4mini it has become possible to create a hotspot with minimal resources and thus get access to the (Digital Voice) DV network.
[NoteRefector is a server connected to the Internet or Ham Net and is linked to a number of digital Ham Radio repeaters. If one of these repeaters is active it will send the voice data stream to the refector- (Xrefectors are the second generation of D-STAR reflectors… etc) – (DCS (Digital Call Server) is the most modern D-STAR refector system and in worldwide use, each as 26 rooms) – (DMR refectors consist of several regional servers, ach other via a superordinate network one Hytera & one Motorola) (System Fusion supports WIRES-X internet linking – .. node station requires external optional HRI-200 !)

The DV4mini is a great UHF digital hotspot. It’s support D-Star, DMR and C4FM* !! Very promising technology in process.

DV4mini-software-01

The DV4mini will be connected thru the USB interface with a PC or a single board computer (es: Raspberry PI 2 Mod. B also a keyboard, mouse and HDMI display) and the required software will be installed: V.1.4 DV4mini Controll Panel.

DV4mini-01

Frequency 420-450MHz – Modulation types: D-Star GMSK (Gaussian 2FSK) – DMR PLUS 4FSK Raised Cosine – C4FM Fusion DN & VW 4FSK, in process* – Power output: 0.03 mW to 10 mW. – RX -120dBm – Read more to the official web-page.

Link to: Download the DV4mini User Manual ver. ENG .Pdf 

I believe not now, it’s available for Windows, Linux and Raspian ! (Raspberry Pi 2) – For those interested in digital communications, like D-Star, DMR and C4FM there’s a new dongle who will be coming out soon (… they are saying it will be available for international shipping next week).

The FT-991’s in Stock in Europe – FT-991 ora è disponibile in Europa

The Yaesu FT-991 HF 50MH VHF UHF Transceiver in Stock in Europe. – The transceiver offers full-fledged support for all modes and include C4FM Digital (4FSK) – Rear panel USB port allows connection to a PC with a single cable (CAT control, Audio interface, PTT/SHIFT control) … at long last!

FT-991-i0gej-00

The new FT-991 is capable of using only 2, C4FM digital modes:
1) V/D mode = communicates Voice & Data simultaneously and using 6.25 + 6.25 kHz bandwidth – [DN] is displayed on the LCD – the station location info is contained within the tx digital signal;
2) Voice FR mode (Full Rate) = trasmits digital voice using the full 12.5 kHz bandwidth – [VW] is displayed on the LCD – the location info is not included in the tx signals;
[Note] Data FR mode (Full Rate) = high speed data communication mode is not supported in the FT-991!  (Data Full Rate by C4FM is not possible).

FT-991-i0gej-02

The new digital mode C4FM (4FSK) spectrum on 29.460 MHz (experimental test in USA) measure about 15 KHz wide in the HF bands!! (Q: Voice is voice, whether it is digital or analog modes? … used only in the FM phone bands?)

CS7000  A NEW MULTIPROTOCOL RADIO by CSI – USA

jerry-Wanger-CSI

This radio is defined for the Amateur Market and will have an introductory price of $249. – Capable of doing DMR, NXDN, dPMR, P25, ANALOG, D-STAR, AND FUSION Protocols. – This radio is built to commercial strandards and will cover commercial Frequencies.
The first version will ship with Analog, DMR, and D-STAR protocols with future firmware updates allowing other protocols – There’ll just be firmware upgrades with which you can add features.!

CSI-specimen

On the CS7000 the (firmware) software is open source, that Hams will evolve the kernel to make it increasingly more powerful to add industry standard protocols.

The primary microprocessor is a STM32F405VGT6. This is an ARM Cortex M4 32 bit high speed microprocessor – The second microprocessor is a DVSI 3000R. This microprocessor uses a TMS320F2811 core and is dedicated to executing the AMBE and AMBE +2 Vocoder formats and other algorithms (!!)

CSI planning on is releasing a single radio that will do both modes of analog and digital. – New expected Delivery is Jannuary  2014 (CSI update 28/10/2014) more news…. see the two link and info below

italianoIn un’intervista esclusiva a http://www.va3xpr.net/, il proprietario e presidente della Connect Systems Inc. – USA, Jerry Wanger parla dei piani produttivi della sua azienda che sorprenderà i Radioamatori con il lancio di questa nuova radio digitale vocale che supporterà sia il Digital Mobile Radio (DMR – TDMA) che, lo Smart Digital Technologies per Radio Amatori (D-STAR o D-star a seconda del sistema proprietario o compatibile in GMSK) – Successivamente saranno completati gli altri modi digitali.

Jerry Wanger prosegue dicendo CHE Il CS7000 porterà un avanzamento nella tecnologia progettuale e il prezzo medio rispetto a quello che è ora disponibile sul mercato, tanto da cambiarlo radicalmente. –  Il progetto prevede un firmware open-source che permetterà ai Radioamatori interessati di implementarlo e ampliarne le possibili applicazioni  tenendo conto dei processori e codec previsti e più sopra indicati.
