-------- Original-Nachricht --------

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
    redesignedFDS 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:

    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:

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
