A significant Flex PSDR upgrade was released yesterday. Others in the SDR community might want to read about the enhancements.
"PowerSDR v2.7.2 is Available for Download
Tim Ellison, W4TME - Customer Experience Manager
FlexRadio Systems is pleased to announce the general availability release of PowerSDR™ v2.7.2 for the FLEX-5000™, FLEX-3000™ and FLEX-1500™ software defined radios. PowerSDR v2.7.2 represents another milestone in the ever continuing improvement of the PowerSDR software, providing new features and defect corrections that make your FlexRadio SDR better with each new software release. New Features
PowerSDR-DataTransfer™ now included with PowerSDR v2.x: FlexRadio Systems is proud to announce a development partnership with RNA Consulting Services, LLC to provide a FlexRadio specific version of their well respected SDRDataTransfer program called PowerSDR-DataTransfer™. PowerSDR-DataTransfer facilitates the migration of database or configuration information from a previous to newer version of PowerSDR. One of the advantages of PowerSDR-DataTransfer is that it automatically takes care of any database changes that may be incompatible from one version of PowerSDR to another. Updated Firewire Driver:
This version of PowerSDR contains an updated Firewire driver for the FLEX-5000 and FLEX-3000 software defined radios. This new Firewire driver contains some bug fixes and a few performance enhancements for Windows 7 and above. In addition to the improvements and bug fixes, this driver has been tested with and is recommended for the recently released Windows 8.1. Enhanced Waterfall Display:
Enhancements have been made to the waterfall display to provide a high resolution representation of the sampled RF spectrum which allows for viewing of signals with better granularity. By turning display averaging off, viewing fine detail of the RF spectrum in the time domain is now possible, eliminating the smearing of spectrum. Additionally, when display averaging is enabled, the default display averaging settings have been modified to display greater spectrum detail along with the ability to easily identify weak signals in the noise. A new checkbox option in the Waterfall section of the Setup->Display tab, "Enable Weak Signal Display Optimization" will adjust the waterfall averaging time and update period to provide the ability to see even the weakest signals at the noise floor. TX Profiles by Mode Option:
There is a new user selectable option that will remember the selected TX Profile by mode. When enabled, the TX Profile selection used for a particular mode is saved and recalled when that mode is selected again. The TX Profile Mode combination is maintained in the PowerSDR database so that it is active when PowerSDR is restarted. The default setting for this option is unchecked. Improved accuracy for Frequency Calibration:
The number of sampled data points used for the Frequency Calibration routine has been increased for greater accuracy. Also, the frequency calibration routine is no longer designated as an "expert" user option making it more convenient for performing frequency fine tuning. New Transmit Compliance for Japan and IARU Region 3:
PowerSDR v2.7.2 has added transmit frequency compliance (TURF) for Japan. This change allows for CW (A1A) operation on the 4.63 MHz Japan National Emergency frequency as well as restricting 60m operation. To enable this feature after installing PowerSDR v2.7.2, you must modify your radio's firmware (TURF) for the Japan Region. To request this firmware modification, please submit a support type HelpDesk ticket requesting the TURF upgrade. In addition to the new transmit frequency modifications; a modified band plan for Japan will be created, displayed under the VFO displays.
Furthermore, in addition to the new transmit compliance for Japan; there is a new TURF option and band plan for any IARU Region 3 entity. As with the Japanese transmit compliance modification, to enable the IARU Region 3 feature, your radio's firmware will need to be modified by requesting the TURF update via the FlexRadio Systems HelpDesk. Enhanced Database Protection:
With past versions of PowerSDR, if Windows or the user initiated a "forced" shutdown of Windows with PowerSDR still running, the database was not given enough time to be completely written to disk before the PC shut down resulting in an inconsistent database. Based on the nature of the inconsistency, the automatic database recovery process may not detect a problem and use a recovery database. The primary cause of forced shutdowns can be contributed to the automated Microsoft update process. PowerSDR v2.7.2 now properly intercepts the forced shutdown condition and properly closes PowerSDR ensuring that the database is properly written to disk before Windows reboots the computer.
For a complete listing of all the enhancements and defect corrections in PowerSDR v2.7.2, please review the PowerSDR v2.7.2 Release Notes.
