Hi Julian, What are you using to analyze the WSPR data after downloading? Thank you. 73... Jon W1MNK g4ilo wrote: 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

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 know many are already aware of this, but take a look N9DSJ-1 (EN52ti) Heard N6TE(DM12) on 3576.23 KHz -8dB at 03:32:00Z using JT65A N9DSJ-1 (EN52ti) Heard K3UK(FN02) on 3575.99 KHz -5dB at 03:32:00Z using JT65A Bill N9DSJ decoded two stations within 24 Hz of each other, how is that for
