Hi, Having followed this thread from the beginning and being a small part of it (in the beginning) I do have some questions regarding the use of the word SPLIT as it pertains to WSJT-X versus its classical meaning on the HF Bands in CW and SSB, i.e. UP 5 or UP 10 etc. First, I would you all agree that while you are in the receive state in WSJT-X, you are listening for the entire band pass beginning at the base, i.e. 14.074 plus a small offset such as 200 and extending to the upper limit of the bandpass that you specified. That does not change no matter where you place your receive goal posts (green). The question now becomes if you are operating split when you move the TX marker away from the RX marker. Suppose you don't have the SPLIT function on, that is it is set to NONE. Are you still operating split if your TX marker is at the edges of the bandpass? Now lets look at it the other way, suppose you set the TX marker at 1500 smack dab in the center, or close to it, and you do have the SPLIT function on, Fake It or Rig it does not matter. Are you now operating SPLIT? How about you have SPLIT on and are on offset 2000, calling someone who is on 500 and he then answered you on offset 2000. Did you operate SPLIT? Here is another question, suppose I am in a QSO, phone, my equalizer is set to emphasize the lower frequencies and attenuate the middle and the highs while my counterparty emphasizes the higher frequencies and attenuates the lower to the middle. Are we operating SPLIT? How about the situation when you need to use either RIT or XIT function in the rig, Are you operating SPLIT? As someone said it, no one owns the meaning of the word SPLIT, but the choice of using the word SPLIT within WSJT-X seems to be the wrong word as it runs counter to its classical meaning in the HAM community and introduces confusion. We all know, or should know, that WSJT-X uses a function, should we to choose to use it, optimize the output power and minimize and distortion no matter where the TX marker is. That function simple shifts things around so that the audio component is somewhere around the center of the bandpass. Anyway, have a great day and enjoy this hobby and especially give thanks to the great bunch of hams who have devoted time and energy to give this great product which I really think is one of the finest arcade game in radio land. 73,
