https://stream.echo6.co/videos/watch/f183ea77-834f-4007-997f-ed6fb2a57854 This video has no narration. The only audio is from GR-DECT2 and the HackRF One real-time decoding the Motorola MBP12 DECT voice channel that’s sitting out next to a TV in another room. It's just a quick test to see if DragonOS Focal's included GR-DECT2 works (fixed for GNU Radio 3.8). https://sourceforge.net/projects/dragonos-focal/files/ I needed to add US Frequencies, but besides that, the HackRF One included flow graph worked well enough to hear audio after selecting the correct carrier number, part, gain, and really just messing around with it till I got it right. I will say that I've heard crystal clear audio, not captured in this video though. GR-DECT2 only works on unencrypted DECT which I can't imagine really exists much anymore. I just happened to find an old baby monitor set online to mess with. Make sure if you personally own DECT that it's at least encrypted. The flow graph is located by default in /usr/src/gr-dect2/grc/ and is named dect2_Hackrf.grc. If you open the QT QUI Chooser for Id: rx_freq and copy paste the following into the Options block overwriting and saving what's there [1897344000, 1895616000, 1893888000, 1892160000, 1890432000, 1888704000, 1886876000, 1885248000, 1883520000, 1881792000, 1899072000, 1900800000, 1902528000, 1904256000, 1905984000, 1907712000, 1909440, 1911168000, 1912896000, 1914624000, 1916352000, 1918080000, 1919808000, 1921536000, 1923264000, 1924992000, 1926720000, 1928448000, 1930176000, 1931904000, 1933632000, 1935360000, 1937088000] then open it back up and copy and paste the following into labels "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "29", "30", "31", "32" and save you will have the expanded US Frequency Channels and ability to select them. Recommend generating and saving the new flow graph to your desktop.
