This radio is in excellent used condition. The optional RX2 second receiver and ATU automatic antenna tuner are factory installed in the radio. Included along with the radio is the Flex hand mic, the 12 volt power cable, a Vantec 2+1 FireWire 800/400 PCIe Combo Host Card for a PC and a 6 foot FireWire cable. This radio was on the air in October 2016. The included PC FireWire PCIe card is plug and play in Windows 7 and 10 in PCs with a PCIe slot on the motherboard. The FLEX-5000A integrates all I/Q data and hardware control over a single FireWire® (IEEE-1394a) connection to a user provided computer. A Fully Software Defined Radio (SDR). Like all SDRs from FlexRadio Systems the FLEX-5000 is a fully software defined radio. The accepted definition of a real software defined radio is one where components that have typically been implemented in hardware e. Mixers, filters, amplifiers, oscillators, modulators/demodulators, detectors. Are instead implemented using software running on a personal computer or other embedded computing devices. The advantages of a SDR over a traditional analog radio, a hybrid DSP/analog radio or “firmware defined radio” are many. Versatility, flexibility and immunity to obsolescence are just a few of the inherent characteristics of fully software defined radios. Don’t be mislead by other manufacturers claims that their radios or accessories are “software defined” when they are just really software controlled or have software defined “like” features. If you are looking for the real deal, a genuine software defined radio, then look no further than FlexRadio Systems and the FLEX-5000. Top Performing Narrow-Spaced Two-Tone 3 rd Order IMD Dynamic Range of 100 dB on 14 MHz Using a 2 KHz Spacing. Not the 20 KHz Spacing Like Everyone Else Advertises! It is becoming evident that close-in dynamic range is the most useful specification to evaluate a receiver’s performance. Receiving narrow bandwidth signals under crowded band conditions are where good receivers are separated from the best receivers. Industry Leading Narrow Spaced 3 rd Order Intercept Point: Greater Than 39 dBm at 2 KHz Tone Spacing. A lot of focus in recent years has been put on the third-order intercept point (IP3) to tout a receivers performance. This specification is not an actual measured number; it is calculated from two other parameters. Therefore the IP3 value can vary dramatically based on the tone spacing used to make the measurements. This is because performance degrades dramatically inside their expensive roofing filters. FlexRadio took a different approach design the receiver to handle large signals at any spacing. That means that with the FLEX-5000 IP3 and thus third order dynamic range will not degrade as tone spacing (even at 100 Hz) is decreased. In practical terms, that means you can work the weak ones sandwiched between the high powered locals. Integrated A/D and D/A Converters. The FLEX-5000 has integrated the A/D and D/A processing hardware built inside the radio. An ultra high quality 192 KHz 24-bit ADC and DACs with exceptional performance provides the spectral samples for the DSP to process. The integrated converters also eliminate the cumbersome and problematic audio cabling requirements between the transceiver and PC that were needed with the first generation software defined radios. True Full Duplex Operation for Simultaneous Transmit and Receive. The FLEX-5000 is a true full duplex transceiver with independent transmitter and receiver signal paths. This means that the software can use the transmitter and receiver simultaneously for monitoring one band while transmitting on another when used with the optional full performance second receiver. With external transverters full duplex satellite operation is also possible. Full duplex operation also facilitates very high speed T/R switching for CW and TOR digital modes. Additionally, the existing MultiRX capabilities that exist in FlexRadio PowerSDR, which allows multiple receive “windows” within the passband of the DSP is also available for the main receiver. This unparalleled capability provides the most flexible receiver configuration of any amateur radio transceiver at any price! Second Independent Receiver (RX2) for True Synchronous Diversity Reception (This option is installed in this radio). Using two separate antennas having different spatial orientations and/or polarization with the optional full-featured, second high performance receiver, true synchronous diversity reception is a reality. Diversity reception is a well know to “top band” operators for improving the readability at the noise floor. By phase locking both receivers to the same frequency you can produce “stereo diversity” which allows your brain to more easily sort out signal from the noise. Other more advanced diversity reception techniques such as beam steering is also possible with the optional RX2 module. Internal Automatic ATU (This option is installed in this radio). A wide matching range antenna tuning unit (ATU) is an optional feature for the FLEX-5000. The switch-L tuning network will tune a variety of unbalanced antenna systems (coax) that facilitates its use with multi-band antennas where the SWR is less than optimal (actual matching range dependent on the complex impedance of the antenna). When used with an appropriate balun, balanced antenna systems can be utilized also. An ATU bypass function will completely remove the ATU from the TX RF signal path. All ATU functions are automatically controlled using FlexRadio PowerSDR as well as having manual control of the ATU. Continuous coverage 1.8 to 54 MHz. Integrated with FlexRadio PowerSDR. Over 16000 memories for instantaneous band changing. Tuning time: 0.5 to 6 seconds, <0.1 second memory tune. Tunes 6 to 1000 ohm loads (16 to 150O on 6M). For Dipoles, Verticals, Vs, Beams or Coax Fed Antenna. FlexWire Peripheral Interface Bus. With the introduction of the FLEX-5000 family of transceivers, FlexRadio Systems introduces FlexWire, an intelligent, high speed, bi-directional communications interface that allows FlexRadio PowerSDR to communicate with a host of peripheral devices such as antenna tuners, rotor controllers and band switchers just to name a few. A family of FlexWire peripherals will be forthcoming from the company. Complete specifications and the programming interface will be published to allow home brew and third party add-on products. Single 1394a FireWire® Connection to your Computer (A FireWire card for a PC is included with this radio). No longer do you have to use parallel port connections to your software defined radio. To fully realize all of the capabilities of the FLEX-5000 and FlexRadio PowerSDR, a high speed RF shielded interface between the computer and the transceiver is a necessity. The FLEX-5000 family of transceivers utilize a single FireWire interface to facilitate access to FlexRadio PowerSDR. FireWire is the optimal technology to deliver high sampling rate radio control and I/Q data with FlexRadio PowerSDR. Redesigned 100 Watt 160-6m Power Amp. Completely redesigned from the ground up, the new 100 watt MOSFET push-pull amplifier produces a full 100 watts PEP on 160 to 6 meters (full duty cycle, 100W ICAS). The PA has excellent spectral characteristics with low IMD and exceptional signal-to-noise (S/N) ratio that produces a phenomenally clean signal. Optimized 11th Order Filters for all Amateur Bands from 160 to 6 Meters. The FLEX-5000 utilizes eleven, individually optimized 11th order front-end filters to cover each of the ham bands between 160 and 6 meters. Since the FLEX-5000 is a full duplex transceiver, there are separate independent filter banks for transmit and receive which is not like other radios where the transmit and receive filters are shared. These individually tuned filters minimize potential interference from strong out-of-band signals for ultra quiet receiver performance. Operators are increasingly making a serious effort to get the highest quality audio within the recommended 3 KHz bandwidth of a SSB signal. The FLEX-5000 easily facilitates interfacing with signal processing equipment by providing a 1/4 TRS balanced audio line input. Using the balanced line-in with a microphone pre-amplifier will allow you to use a variety of ribbon, dynamic and condenser microphones for the configuration that best fits your operating needs. Or you can achieve studio quality audio by deploying a complex audio chain with equalizers, compressor/limiters, aural exciters and other effects processors. Note: A microphone is not included with the FLEX-5000A. High Stability TCXO for Accurate SSB, VHF+ and Digital Modes. Frequency stability is critical when operating VHF+ or HF digital modes. The FLEX-5000A incorporates a high stability temperature-compensated crystal oscillator (TCXO) which reduces frequency drift to no more than ± 0.5 ppm. For even greater frequency stability, the FLEX-5000 has a software switched, external BNC connector for connecting a 10 MHz GPS disciplined or other high stability clock source. Three Software Selectable Antenna Connectors. The FLEX-5000 has three independent SO-239 antenna connectors that can be assigned as transmit and/or receive antennas by operating band and mode. Separate Dedicated Receiving Antenna. Not all antennas have perfect reciprocal characteristics, meaning that a good transmitting antenna is not necessarily a good receiving antenna. This is especially true at long wavelengths of 80 and 160 meters. Hams that are serious about "top band" operating know the advantage of using a beverage antenna for receiving. They also know that they are very poor for transmitting. To overcome this dilemma, the FLEX-5000 has a dedicated receiving antenna connector. In fact, it provides both a RX output and a RX input (loop) to allow the use of preselectors and preamps "in-line". Transverter Ready - Full Duplex 28 MHz IF. The FLEX-5000's incredible receiver is perfect for weak signal VHF+ and WSJT operation as a 28 MHz IF for interfacing to external transverters. The FLEX-5000 will turn your VHF-UHF-microwave setup into the highest performance station around. Full duplex operation opens the door for satellite communications as well. Three TX Control Lines for Keying Amplifiers, Transverters, Sequencers and Other Accessories. Keying external amps, sequencers and preamps is always a daunting task, but the FLEX-5000 makes it so easy with three user assignable TX control or keying lines with variable time delays. Each TX control line can be configured on a per band basis allowing the control of multiple devices. No External Calibration Equipment Required. The new FLEX-5000 family incorporates Built-In Test Equipment (BITE). This includes a swept signal generator, power sampler, and transmitted signal spectrum analyzer. The radio is capable of testing and calibrating itself. All models are factory calibrated and aligned to exacting standards. Audio Line-In and Line-Out Connectors. The FLEX-5000 has consumer level (-10 dbV) line-in and line out RCA type connectors for a variety of uses, such as recording audio from a contest so you can listen to that rare DX to make sure you don't have a busted call or output streaming audio to the web from your FLEX-5000. FlexRadio Systems takes environmental issues very seriously making concerted efforts to minimize the impact of our products on the Earth. As such, the base FLEX-5000A transceiver is in compliance with the RoHS (Reduction of Hazardous Substances) directive for minimizing the amount of hazardous materials in its construction by using lead-free components and manufacturing techniques. FlexRadio PowerSDR and the FLEX-5000 - An Awesome Combination! The FLEX-5000 family comes with FlexRadio PowerSDR software that performs all DSP, modulation, demodulation and control functions for the radio. FlexRadio PowerSDR is the "brains" behind the FLEX-5000's "brawn". With the release of the FLEX-5000, FlexRadio PowerSDR has been significantly upgraded and optimized to use a true multi-threaded architecture that greatly improves transmit and receiver performance.
