This video shows the first test after completing assembly of Softrock RXTX Kit . To do that I chosen the frequency 28730 kHz, intended for experiments on 10 meters band. The power used was 1 Watt. The antenna was a homebrew magnetic loop. The software was HDSDR. The receiver radio was a DEGEN 1121.I used the internal sound card for RX and extern sound card to TX.Results: 1) The distance did not exceed 30 meters. Maybe a problem to be solved in the next steps;2) I observed a small offset in the frequency transmitted compared to the received by the radio (DEGEN 1121). Maybe need calibration.73,PU2CLR.Ricardo.Brasilia / BrazilQRZ: http://www.qrz.com/db/PU2CLRReferences: http://fivedash.com/index.php?main_page=product_info&cPath=1&products_id=6http://www.hdsdr.de/http://en.wikipedia.org/wiki/Software-defined_radioReferências em Português:http://www.ajmesquita.qsl.br/?page_id=344http://www.cram.org.br/wordpress/?p=2122
