R&S® M3TR Software Defined Radios Multiband, Multimode – New software V.7.0

R&S®M3TR Software Defined Radios (Front panel on the image) – The new software Ver.7.0 supports third-generation Automatic Link Establishment (ALE 3G)* in line with the STANAG 4538 NATO standard. If a shortwave consumer receiver could do what this shortwave milspec transceiver hi!!

The heart of the new integrated communications system is the lightweight R&S®MR300xH/U manpack transceiver (1.5 MHz to 108 MHz or 25 MHz to 512 MHz), which offers solutions for all aspects of tactical communications - New Software Makes Rohde & Schwarz Shortwave Radios As Easy To Use As IP Phones -
Last-ditch voice enables reliable voice transmission even when the noise is stronger than the voice signal, ie with a negative signal-to-noise ratio. - The quality of shortwave links heavily depends on ambient transmission conditions such as solar radiation and atmospheric ionization – The software automatically adjusts the transmission rate to accommodate prevailing conditions. – Release 7.0 of the software also features the high throughput data link (HDL) protocol that allows transmission rates of up to 10 kbit/s under optimal conditions.

ALE 3G * - The latest ALE standard uses accurate time synchronization via GPS-locked clocks or a time server to achieve faster and more dependable linking. – It is generally known as 3rd generation or 3G ALE.

FLEX-3000 SDR Transceiver: is the new FlexRadio mid-range 100 watt HF 50MHz

 
FLEX-3000 is new FlexRadio mid-range 100W tramsceiver, delivery in January 2009 .  Il FLEX-3000 è una “diretta decedent” del FLEX-5000 ™, un transeiver SDR (Software Defined Radio) per uso amatoriale di prima classe per performance.
Il FLEX-3000 utilizza Filtri di Banda individuali ottimizzati per coprire sia le bande dei radioamatori (filtri di 5°ordine ottimizzati per ciscuna Banda, fatta eccezione per 160m che ha un filtro di 7° ordine) e di un LPF per la copertura generale. The FLEX-3000 è già dotato di un unità di antenna tuning (ATU), tutte le funzioni dell’ATU sono controllate automaticamente dal programma FlexRadio PowerSDR, oltre ad avere il controllo manuale. Il ricevitore usa un convertitore A/D con velocità di campionamento a 48 o a 96 KHz. FLEX-3000 utilizza lo stesso PA realizzato come quello montato nel FLEX-5000, quindi non è stato sviluppato un nuovo amplificatore di potenza da 100W, ma un collaudato progetto già ben provato. Se necessario, la radio è in grado di esergure, manualmente, un auto-test di controllo o di calibrazione.
FLEX-3000, come in tutte le versioni del FLEX-5000, viene fornito con software FlexRadio PowerSDR V.1.x, che controlla tutti i comandi DSP, la modulazione, la demodulazione, il filtraggio e tutte le funzioni di controllo per la radio, oltre a gestire l’analizzatore di spettro (Panadapter display) di classe da laboratorio di misura. FLEX-3000 utilizza la stessa interfaccia Firewire® 1394 per il PC o per Laptop, come il Fx-5000.
Prezzo (Usa) introduttivo di $ 1.499,00 (List 1.599,00) The FLEX-3000 is on sale *now* and is scheduled for delivery in January 2009.

NOTE: The IMD DR3 and IP3 measurements are currently being performed and will be published shortl;
NOTE: The depictions of the FLEX-3000 shown above are of the current prototype unit;

ENG: The FLEX-3000 is a “direct decedent” of the FLEX-5000™, the full-featured, world class software defined radio transceiver for amateur use. The FLEX-3000 utilizes individually optimized bandpass filters to cover both the ham bands (Optimized 5th order bandpass filters for each ham band except for 160m which has a 7th order filter) and general coverage reception (low pass filter).The FLEX-3000 comes with an antenna tuning unit (ATU) as a standard feature, all ATU functions are automatically controlled using FlexRadio PowerSDR, as well as having manual control. Rx A/D converters running at either 48 or 96 KHz sampling . The FLEX-3000 uses the same PA design as the one found in the FLEX-5000, so this is not a newly developed RF power amplifier 100W, but uses a well-vetted design that is tried and true. The radio is capable of manually testing and calibrating itself if necessary. The FLEX-3000, like the world-class performer FLEX-5000, comes with FlexRadio PowerSDR 1.x software that performs all DSP, modulation, demodulation, filtering and control functions for the radio in addition to the lab grade spectrum analyzer Panadapter display. The FLEX-3000 uses the same Firewire® control and interface circuitry as the Fx-5000
