My own brain, pencil and paper. :) I just average out the reports from different stations. I use two different transmitters to send two WSPR transmissions at the same time and using the same power on different frequencies using the antenna under test and the one I am comparing it to. Julian,

I don't think you can impute anything meaningful from one set of reports. Normal QSB will make a difference of from several to many dB which can only be averaged out over a period of time. WSPR is much better IMO for this sort of thing. You can leave it running, go and do something
