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)

Yaesu introduces “System Fusion” for C4FM 12.5 kHz Digital & DR-1 a Digital/FM Dual Mode Repeater, Not D-STAR Compatible!

Yaesu_DR-1_mixed-mode

Yaesu DR-1 a new Digiatl C4FM and Analog FM  Multi Mode Repeater with AMS (Automatic Mode Select) – Yaesu introduces the System Fusion  joins FDMA Digital and Analog FM Communication into a single multiple function system. It provides total integration and compatibility of both Digital & Conventional Analog FM communication – And the latest VoIP interface,  the new wireless WIRES-X a Internet Linking HRI-200, will also be available in Nov., 2013. !! The Yaesu FDMA “C4FM” system is not compatible with the D-STAR “GMSK” Digital mode. !! (one only has to look at Yeasu’s record of going against the tide ! – IØgej)

DR1-front_Set-2013

The DR-1 Repeater C4FM/Analog FM and AMS – FM Friendly Digital – Easy Migration – Yesu writhes: Replace your Conventional Analog FM repeater to: 1) provide continued use of Conventional Analog FM communication 2) while integrating the use of Digital Communication functions. – Modulation Mode: 25kHz for FM & 12.5kHz fot C4FM Multiple mode. – Ouypuy Power 50W/25W/10W Large-size Heat-Sink & Cooling Fan builtin. –  (please click pictures to enlarg!)

DR-1_setup-1 DR-1_setup-2

DR-1_AMS_dig-fm

Yaesu “System Fusion” : System Fusion joins Digital and Analog FM Communication into a single multiple function system. – It  provides total integration and compatibility of both Digital & Conventional Analog FM communication.

The AMS (Automatic Mode Select) function that instantly detects the received signal mode (AMS automatically recognizes  hether the siganal is a C4FM digital or analog FM signal, and transmits using the set communication method by DR-1 setup).

FDMA_multiple-modeMulti Mode FDMA/C4FM – FM – Bandwidth 6.25+6.25 kHz or 12.5 kHz – provides 9.6 kbps data baud rate speed! ability to transfer large amounts of data! – The D-STAR DV provides 4.8 kbps into a only 6 kHz bandwidth! – Yaesu FDMA multi mode:
1) V/D mode – Voice/Data simultaneous communication mode; 2) Voice FR Mode – Voice Full Rate Mode; 3) Data FR mode – High Speed Data Communication Mode; 4) Analog FM mode – (conventional Analog FM). (see the picture)

[Note] …Yaesu va quasi sempre controcorrente Hi !!
Wires-x_HRI-200In the world we developed IRLP and Echolink. Yaesu went against IRLP and Echolink and created WIRES-II – (latest -X) HRI-200 … This commercial stuff fits 2 voice/data channels into one repeater DR-1. Yup, but at twice the bandwidth of D-STAR! … Yaesu is coming out with “DMR” radios soon, but Motorola, Hytera, Vertex, Icom and Kenwood already exist .. Mototrbo – dPMR – IDAS – NEXDGE – (DMR FDMA & TDMA is an open ETSI standard) – There are advantages and disadvantages to most new technologies, but it’s often the case that the supposed benefits are just that, supposed !! (identically allows us to compare FM and D-STAR etc.).

italianoLa Yaesu Musen Co., LTD ha svelato ora la sua nuova piattaforma digitale definita “System Fusion” multimodo, presentando anche il suo Yaesu DR-1 che può essere configurato per consentire di “fondere” i due modi con selezione automatica (AMS) del tipo di modulazione. – Questo permette, dice Yaesu, l’integrazione tra la tradizionale FM e il digitale C4FM, un FDMA già noto come “DMR” in uso da tempo nel commerciale da parte di quasi tutti i produttori di radio! (..Motorola, Hytera, Vertex, Icom e Kenwood già producono con il DRM e alcune variabili proprie… come: Mototrbo – dPMR  -IDAS – NEXDGE etc. (il DMR, FDMA & TDMA è un sistema aperto in Standar ETSI) –

FTM-400D_c4fm-finding FTM-400D_menu-setup-1 FTM-400D_menu-setup-2

Qui sopta immagini del veicolare FTM-400D (USA) o FTM-400E (EU) – Comunque si vedono diverse novità  introdotte con il sistema Yaesu a canale di 12,5 kHz porta fino a 9,6 kbps il “data baud rate speed” che abilità il trasferimento di una più alta massa di dati! – Il D-STAR DV normale ha 4.8 kbps, però solo su 6 kHz di bw canale. – Per questo il C4FM avrà un audio migliore anche per il BER-FEC più veloce – Altra buona differenza: con l’utilizzo del Ripetitore DR-1, un utente con nuovo apparato digitale può trasmettere in digitale, il ripetitore DR-1 converte il segnale C4FM digitale in FM analogico per altri utenti con apparati non digitali e viceversa (ecco la “fusione”!) –  Il ripetitore è configurabile (in AMS – FIX o AUTO) tramite un’interfaccia touch-screen direttamente dal suo pannello frontale.

[Nota]  Yaesu va quasi sempre controcorrente Hi !
Nel mondo radioamatoriale si è ben affermato lo standard IRLP e Echolink, loro hanno introdotto l’interfaccia VoIP wireless per Internet detta WIRES-X (Ver. I/II/..X); – Poi con già più di 1000 ripetitori D-STAR in “GSMK” attivi nel mondo e collegati con Gatewai in varie reti internet già sviluppate appositamente dai Radioamatori, Yaesu introduce un “DMR” digitale che è sempre in standard FDMA, però con modulazione “G4FM” (4xFSK) e 12.5 kHz di BW, non compatibile con il D-STAR! – Sarà un nuovo gioco per questioni commerciali o veramente una innovazione anche per i Radioamtori? Aspettiamo e si potrà verificare. – Sempre troviamo vantaggi e svantaggi per la maggior parte delle nuove tecnologie, ma spesso capita il caso che i presunti benefici siano solo presunti! (potrebbe esserlo anche per il confronto tra i modi FM e D-STAR, certo!).
