7/1/2023 0 Comments Using fldigiMy Soundcard is set to use PortAudio with capture and Playback set to the two QDX devices. Under Sideband, I have selected Rig Mode although I have also tried Always USB. The COM port is correct for my system and I used a baud rate of 115200 although this should not make a difference since the COM port is virtual. I am using Hamlib with TS-480 as a rig (I have also tried TS-440S). The QDX was set to use 1 sample rather than 480 samples via the terminal interface. I am currently using the latest version of Fldigi at 4.1.20 running under Windows 10 on both computers that I am using for these tests. The other transceiver is an Icom IC-7700 which has been used to make Olivia contacts previously, but with an earlier version of Fldigi. I have been careful to not overload either receiver. I have also monitored the QDX signal on another transceiver here in the shack connected to a dummy load. The mode that I am most interested in is Olivia, but I have been testing RTTY since I have a friend here in town who also has a QDX and he has been very successful at making RTTY contacts with his QDX. I have made over 800 FT8 contacts with this little fellow! I want to use the QDX with Fldigi to try some compatible single tone modes but I am experiencing some problems. I finished putting together my QDX Rev 2 kit approximately 3.5 weeks ago and it appears to be working well with JTDX (derived from WSJT-X).
