Hi Julian,
What are you using to analyze the WSPR data after downloading? Thank you.

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 interesting, then come back later and
download all the spots and take an average. You can also transmit
simultaneously on two different frequencies using the test antenna and
a reference one and compare the reports each one gets. (You have to
start the transmit cycles manually in that case, there is no facility
in the software for two copies of the program to use the same pattern
of transmissions.)
