<br>Screenshots listed and end.<br><br>README:<br><br>It currently builds and runs on Linux. It identifies and uses up to<br>seven (theoretically eight) USB RTL2832U-based DVB-T dongles. The<br>dongles can be set up with an up converter or use RTL direct-mode<br>
for HF receive. Or direct input to provide it's native > HF receive<br>range.<br><br>The program can be passed in a variety of command line options.<br>One of which is a frequency offset not only for up converter use<br>
but also to allow a full range of frequency options to HPSDR programs<br>that are coded to only allow the real HPSDR radio's (i.e. Hermes)<br>frequency range which is from 10KHz to 55MHz.<br><br>The main purpose of this program is to provide a mechanism that<br>
allows RTL Dongle owners the ability to use them on HPSDR specific<br>software programs.<br><br>One such program, cuSDR64 has the ability to control and display<br>up to 7 rcvr slices simultaneously. With rtl_hpsdr, if your host<br>
has the horsepower, you can run 7 RTL Dongles to emulate the HPSDR<br>rcvr. cuSDR64 also can be built and run on Linux.<br><br>Since the real HPSDR (i.e. Hermes) rcvr can do up to eight rcvr<br>slices, there is a concept of 'COPY' rcvrs in this server. This<br>
would allow one to use HPSDR programs that expected more rcvrs<br>than were attached. Currently if a program request more rcvrs<br>than are actually attached the rtl_hpsdr server will make copies<br>of the last 'real' rcvr. This alows one to only have one RTL dongle<br>
attached and run PowerSDR mRX which may expect up to four rcvr<br>slices.<br><br>Refer to: <a href="http://openhpsdr.org/softwareinfo.php" target="_blank">http://openhpsdr.org/softwareinfo.php</a> for a list of<br>HPSDR supported applications.<br>
