However, additive IM products can produce problems in the JT65 segment 2 kHz above the FT8 segment. At 1500-2000 Hz the nearest IM products will be 0-500 Hz below the passband, or at 3000-4000 Hz, which is also outside relevant frequencies for FT8. If your desired stations transmits below 1000 Hz and you reply with a corresponding audio signal below 1000 Hz, the risk of creating IM within the TX passband is much higher. In both cases the point is to make sure that the TX audio signal stays in the middle of the TX passband at 1500-2000 Hz in order to avoid intermodulation problems from the transmitter in the TX passband.

The 'Fake it' choice, I assume is made for radios where WSJT-X has to 'help' the radio, by changing the single VFO frequency while transmitting and change it back to the receive frequency while receiving. Like 'all' modern HF radios, both radios have ordinary split functions and therefore 'Rig' can be selected and it will work just like working split in a pile-up. Talking about the Radio setup at 4:42 you mention that you want to use 'Fake It' for Split operation in the IC-7300 and IC-7610.

The next one now is instant upload to LoTW and ClubLog. WSJT-X was built expecting it to be run by CAT control, and that is an important reason why efficient CAT control was built into WSJT-X from the start. I guess your video simplifies matters a bit for many, reducing the number of variables to miss. The HRD suite is great for many purposes, but in this context the CAT part is not needed, only the HRD Logbook. Click to expand.Rich, thanks for taking the essence out of the previous discussion on WSJT-X, HRD CAT and Logbook and JTAlert, and making a video about the bare essentials needed.
