A new free release of WRplus, 1.05 is available for download from 
www.wrplus.altervista.org <http://www.wrplus.altervista.org/> .

As you probably already know, in early 2011 the WRplus code has been 
acquired by "SDR Applications" a new company in the field, so it's going 
to be a commercial product with all the related benefits; in the near 
future a new software, which will collect the legacy of WRplus, will be 
available featuring a completely renewed user interface and several more 
options.

As this new application will not be available before September-October 
2011 we at SDR Applications have decided to release another free version 
of WRplus; from today this "ad interim" time-limited release is 
downloadable.

Here in short the new features, modifications and corrections:

   * New Fractional Resampler: as emerged in several performance tests,
     the original Winrad fractional down-sampler (FDS) has a poor
     attenuation of alias product; WRplus 1.05 feature a totally
     redesigned FDS with a worst-case alias attenuation of about 130
     dB. Do yourself a test using the file that Leif Asbrink has kindly
     provided; it is available here:
     http://sm5bsz.com/lir/sim1/sim1.zip
     Check also the tests performed by Leif here:
     http://www.sm5bsz.com/lir/sim1/sim1.htm
     Soon the above page will hopefully be updated with the test of
     WRplus 1.05.
     Another test file by Alberto Di Bene I2PHD is available here:
     http://www.sdradio.eu/audio/t1n24_500kP.rar
     This feature is offered as a partial preview of the future
     software capabilities.

   * Extended Tuning Range: In WRplus 1.05 the range of the Tune and LO
     dials have been extended from 1 GHz to 2 GHz with the addition of
     1 digit.

   * Fixed some minor issues with RDS

   * User Guide updated.

Please read the updated User Guide and the history.txt file before 
posting questions.

As always feedbacks and comments are welcome.

Thanks to all for the feedbacks and advices.

Sandro Sfregola
