On the most MUXes there was no noticeable difference. However when doing the test in rainy, windy weather with dismal lift QT-DAB4.3 + RSP1A managed to decode <br>12B Li\u00e8ge quite easily. <br>QIRX3.2.1 + RSP1A managed it too but with more difficulty and most of the time only partially. QT-DAB and QIRX couldn&#8217;t do it when connected to the RTL-SDR R820T. Under normal conditions the difference between the set-ups became negligible. <\/p>\n\n\n\n<p>It&#8217;s vital to set-up bandwidth for QIRX + RTL-SDR R820T correctly to around 1700 kHz. AGC works very well in this combo. For QIRX + RSP1A do check the Gain <span style=\"text-decoration: underline;\">Reduction<\/span>. Its default setting is 3. The higher the number the more reduction! <br>In general QIRX tends to show the TII codes quicker and more extensively than QT-DAB.<br>QT-DAB settings need to be checked too. AGC works well. Using RSP1A again note the LNA state selector indicate the Gain <span style=\"text-decoration: underline;\">Reduction<\/span>. The higher the number the less Gain. Using RTL-SDR R820T with the Autogain on you should toggle the ppm. <br>In general strong MUXes need a lower ppm.<\/p>\n\n\n\n<p>Do have a look at the manuals from <a rel=\"noreferrer noopener\" href=\"https:\/\/qirx.softsyst.com\/DABDemod\" target=\"_blank\">QIRX<\/a> and <a rel=\"noreferrer noopener\" href=\"https:\/\/github.com\/JvanKatwijk\/qt-dab\/releases\" target=\"_blank\">QT-DAB<\/a>.<\/p>\n\n\n\n<a href=\"http:\/\/wijnants.info\/fmdx\/wp-content\/uploads\/2022\/01\/RSP1A_R820T.jpg\" target=\"_blank\" alt=\"QIRX+RSP1A vs QT+RTL-SDR R820T\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/wijnants.info\/fmdx\/wp-content\/uploads\/2022\/01\/RSP1A_R820T-800x450.jpg\" alt=\"QIRX+RSP1A vs QT+RTL-SDR R820T\" width=\"444\" height=\"244\"><\/a>\n\n\n\n<p><\/p>\n\n\n\n<a href=\"http:\/\/wijnants.info\/fmdx\/wp-content\/uploads\/2022\/01\/R820T_RSP1A.jpg\" target=\"_blank\" alt=\"QIRX+RTL-SDR R820T vs QT+RSP1A\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/wijnants.info\/fmdx\/wp-content\/uploads\/2022\/01\/R820T_RSP1A-800x450.jpg\" alt=\"QIRX+RTL-SDR R820T vs QT+RSP1A\" width=\"444\" height=\"244\"><\/a>\n","protected":false},"excerpt":{"rendered":"<p>QT vs QIRX &#8211; RSP1A vs R820T For DAB+ DXing QIRX and QT-DAB are great software, while RSP1A and RTL-SDR R820T are excellent hardware.
