The very best RBN comparisons are for an entire contest, between two stations in the same metro area, or same part of a state, in the same general geographic category. There is an RBN beta graph function that will allow you to pick an RBN station and then the call signs for comparison on the graph. You can then see a day's worth of signal readings on two different color graph lines. You can discern even 2 dB of difference quite reliably. It doesn't tell you why of course. But it does a really good job of how much. You can also download a whole day's worth of readings and import them into Excel for further analysis. If you can get yourself within a few dB of a good performing station, you will do well. If there are time of day dependent differences, those will show up too. 73, Guy _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
