A QRS beacon can send the call continuously all day and successive periods are often used to establish the information. How about comparing like for like in the timing of Data Bits, OPERA uses digital techniques and no doubt repeats the data in the 4 minute period of OP4. In this case we would need to be comparing it with QRS1 or QRS1.025 if you like. I feed a coding session coming on. 73 Eddie G3ZJO
