Initially, I was going to send this to another person, but in rereading your message, I cut 'n paste it to you. It was more appropriate.
What are your thoughts regarding the position of your signal on a given frequency, perhaps 7076, or 18102? One forum member strongly recommended in a message a couple of days ago to make sure the transmitter was REALLY, REALLY close to the station being monitored. This will enable both parties to decode each other without taking up too much bandwidth. He also made the comment that he had been set up fairly narrow and missed a DX contact because he was not printing the DX, even though the DX station was calling him nearby. He wants an effort made to tune the transmitter to the sync tone position of the station you're copying. With RIT off, and my ICOM IC-746 tuned to 18102 and printing a station, won't I be right on frequency or really close to him and his sync tone position as such? In my mind, that will not happen unless by chance, it seems to me. I'm asking because I had thought that my transmit frequency would be changed much like for PSK but it apparently is not the case. So, if that is so, I wonder what the correct protocol would be to accomodate many stations on or about 14076, 18102, 7076, etc etc? AND, not take a huge amount of bandwidth in each case, a protocol that we can all agree upon and adhere to as applies to HF ops with VFO controlled equipments? Otherwise, if I'm trying to tune my ICOM so that his sync tone is "zero beat" or whatever, in WSJT, it'll take forever due to the very slow decode processing that occurs. Hmmmm.......is this software normally used with channelized radios on VHF/UHF? What if we set up specific frequencies to operate on, sort of like mini- channels; so many Hz between each one? With RIT off, maintaining USB or LSB consistently, with today's radios, wouldn't better operating practices be enjoyed along with fairly consistent success? It seems to me that the matter of the importance of the Sync Tone would be better addressed than by happenstance. Just asking newbie questions, perhaps with an air of the mushroom notwithstanding.
