Hi Adrian, This start to be really funny!
Let me take a real scenario that I participated. If I remember correctly it was a FT8 contest and there were a rare station, at least to me, K1JT. So everybody called him, including me, quite a pile-up on his transmit frequency. Joe tried to manage that pile-up by sending message 'USE SPLIT PSE'. What he meant by that? Did he recommended that everybody should use Split operation 'Rig' or 'Fake It' while working him or something else? If he meant Split operation, how he knew that the operators were selected Split operation 'None'? He had no access to other stations rigs nor monitor function of those rigs. By magic, perhaps. No, no, he meant use Split working i.e. send on another frequency that where he is sending. I did and managed to work him, but he never sent 73 to my RR73, but that's another story as I was novice at that time. Adrian, split *working* means that you are sending at a different frequency (as seen on antenna connector) than the station is transmitting while you try a QSO or have a QSO with that specific station. That is the split *working* what is discussed. Of course there may be also that split *operation* your see happening in your rig, but nobody else sees it. It is just a way how your 50 Hz wide transmit frequency is generated (by double or triple mixing depending on your rig). Now the receiving part of a QSO. What it means? There are two stations, yours and the DX station. You see the DX station on a specific frequency on the waterfall. Once you call him by double clicking or answering to the DX station's call, your Rx green goalpost jumps to that frequency. Why it needs to do that although you see all the stations at the same time? The green goalpost indicates the frequency, where your decoder starts decoding i.e. it is your most important received frequency at that time. All other station you see in the Band Activity are just extra, but those are not any part of your current QSO. So the green goalpost is your receiver frequency. All others are from your FT8 skimmer as an extra for you. Saku's SDR functionality description was an excellent way to say the same. To wrap-up: there are two splits. One for split working also known as classical split and the other for split operation that is a totally local issue how the transmit signal is generated. The first is seen by other operators and latter is hidden inside the transmitting station. Perhaps my last pennies on this subject, hi! Have all fun! 73, Reino OH3mA _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
