WSJT-X Split Operation 

When working with the WSJT-X program, it would make sense to use Split Operation. Not that long ago, a certain WSJT-X Facebook page wrapped up a poll that revealed peculiar results. “Fake It” is used by twice as many Ham enthusiasts than “Rig” when it comes to Split Operation. And there are plenty of those using “None” as well out there. 

Despite the fact that contemporary HF transceivers have the possibility of using “Rig” for Split Operation, most enthusiasts will still refer to “Fake It” since they are experiencing radio problems, certain issues with timing, etc. One way or the other, practice shows that both work pretty well. However, one must also keep on mind that if they are using the Icom 7300 or 7610 and Ham Radio Deluxe for the Rig in WSJT-X, they will need to be using “Fake It” for Split Operation to begin with. 

The Split Operation that K0PIR refers to here implies the setting on the Radio tab in WSJT-X program. There are three choices present for the split – Fake It, Rig or None.

The Split mode comes with a series of substantial perks, so it’s always nice if your radio does support it. However, even if the radio does not support it in the first place, the WSJT-X program will emulate it for you. Both options will lead to much cleaner transmission and will keep the audio in the range of 1500 to 2000 Hz. That way, the audio harmonics cannot pass through the Tx sideband filter. 

There is also one other peculiar reference that’s known as “Hold TX Frequency”. 

Users with actual experience often ask not to call them on their transmit frequency and it’s a rule that makes sense – particularly so in a DX pileup scenario. 

In case you will opt for the “Hold TX Frequency” selection in WSJT-X in order to hold the TX frequency and afterward put your red TX indicator in a clear spot on the word waterfall, there is a pretty big chance that you will reach the station that everyone and their mum is calling in the first place. 

In the end, I would urge everyone to opt for the Split Operation. Sure, it may require some getting used to but even if it does not work for you, you can always resort to “None”. Check to learn much more about it and make the right call based on all of the accumulated info.
