Top Performing Narrow-Spaced Two-Tone 3rd Order IMD Dynamic Range at 2 KHz - (Not 20 KHz Like Everyone Else Advertises). An Incredible 105 dB on 14 MHz...
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. Most radio manufacturer's do not publish their 2 KHz two-tone, third-order dynamic range values because it is easier to get better looking numbers at 20 KHz that are not that applicable to real world operating conditions. The FLEX-5000 at 2 KHz spacing, exceeds traditional radio manufacturer's top of the line performance by as much as 10-25 dB, depending on the model.
Industry Leading Narrow Spaced 3rd Order Intercept Point: +33 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. The $10,000 radio manufacturers publish wide-spaced (20 KHz) IP3 values of +40 dBm, but shy away from reporting the "real world" close-in IP3 values. Why? 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, as well as its SDR-1000 predecessor, 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.
No Sound Card Required!
No longer do you have to worry about interfacing a sound card to your PC. The FLEX-5000 has integrated the A/D and D/A processing hardware built inside the radio. A high quality 192 KHz 24-bit DACs with exceptional performance numbers provides the spectral samples for the DSP to process. The integrated converters also eliminate audio cabling requirements between the transceiver and PC
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 you 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. On phone and digital modes, you can hear and see the spectrum of your actual transmitted signal. Full duplex operation also facilitates very high speed T/R switching for CW and TOR digital modes. Additionally, the existing MultiWatch™ capabilities that exist in PowerSDR, which allows multiple receive "windows" within the passband of the DSP is also available for each receiver. This unparalleled capability provides the most flexible receiver configuration of any amateur radio transceiver at any price!
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
Power SDR™ and the FLEX-5000A: An Awesome Combination!
The FLEX-5000™ family, like the ground breaking SDR-1000, comes with PowerSDR software that performs all DSP, modulation, demodulation and control functions for the radio. PowerSDR is the "brains" behind the FLEX-5000's "brawn". With the release of the FLEX-5000, PowerSDR has been significantly upgraded and optimized to use a true multi-threaded architecture that greatly improves transmit and receiver performance. This is most notable when operating full break QSK at 40 WPM where you can actually hear between the characters.
