i'm not thinking anything because i really dont know what the split is? he said "Generaly" which means exactly that, that there are certain instances where its different. Im just making sure my area isnt one of thoughs exceptions or absolute 800mhz areas, because quite frankly even if it was i wouldnt have anyway of knowing with out some one telling me. Like you telling me that only an absolute 800mhz. area would be different, i didnt know that. thats why i am asking. I know my areas RX freq.s but not the TX which, to my knowledge and from what i see, you need both when entering in the system freqs in ProGrammer. all i ever see is just the RX freqs posted. I knew there was an equation i just didnt know what it was. Someone else wrote the personality from are and ive lost it so i dont know what the split and i'm having to configure it manual. I do know what I am doing in ProGrammer i just didnt remember the split equation. The 2 areas of interst are on here, 1 in west texas and the other is in Canada.(i know. dont ask)
