Uccess! My first librtlsdr application

Hi First, my thanks to everyone involved with the development and release of librtlsdr. Well done. :-) I always wanted to try my hand building an SDR application and so I installed the latest librtlsdr and started writing code to test the various functions in the librtlsdr library. Having gotten familiar with this, I started work on modifying my old Wx satellite APT image decoder app, xwxapt, to support an rtlsdr receiver beside the linear VHF receiver it was written for. Its always difficult to extensively modify an existing app, but in the end it all worked out well and xwxapt can now receive the old APT format images from Wx sats with the rtl-sdr receiver. In the process, I modified xwxapt to include controls for the rtl-sdr unit, display an FFT-derived spectrum of the 2.4kHz sub-carrier and a spectrum of the baseband O/P of the RTL2832 device. Images are decoded in real time and displayed incrementally in xwxapt's window. xwxapt is available under the GPL at: http://www.5b4az.org/ in Weather Imaging->Image Decoders menu. -- Best Regards Neoklis - Ham Radio Call:5B4AZ http://www.5b4az.org/
