Wideband HF – Modernized for ultimate BLOS performance.

FlexRadio’s ML-9600W wideband Software Defined Radio is the ultimate platform for commercial and government HF applications. This Commercial Off The Shelf (COTS) transceiver can support up to 78kHz* transmit bandwidth and up to 1.8MHz* receiver bandwidth to support the latest modernized waveforms.

The fully integrated modem provides native use of modern protocols and waveforms including: 2G/3G/4G ALE, MILSTD-188-110D, MIL-STD-188-141D, STANAG 4285, 4415, 4529, 4538, 4539 and 5069.

With built in IP-based Ethernet communications the transceiver can be operated locally with an included Windows application, optional iOS/ MacOS software interface or through custom applications via an open API.

For rapid deployment or prototyping of waveforms, we offer an optional GNU Radio source/sink interface compatible with multiple operating systems. The SmartSDR™ open API allows for developers to create custom applications and waveforms to interface directly with the radio using plain language commands and standard VITA- 49 streaming RF/IF and FFT data.

The ML-9600W includes a +10dBm exciter output that can be combined with FlexRadio’s COTS high power, modular RF Power Amplifier solutions up to 10 kW such as the FPA-5K and FPA-10K.
