Hi Paul: that seems to match with the interval I am hearing here between the two sweeps then the long interval, but, why do they do the wide freqencey range, if that is what I am hearing. is it a pulsed signal? I did not know that till looking at it, as it sounded clean as it swept through wherever I was listening. if so how can they legally transmitt on that entire freq range?
