If you have ever wondered why you only get a signal report of say 429
when you are giving 579 it is because the station is transmitting on a
vertical and receiving on a loop. It is not a reciprocal signal exchange
and therefore makes a nonsense of signal strength reports under these
circumstances.
In fact the rx loop might not be orientated in the direction of the
transmitted signal.
Another consideration is a person that has asymmetrical ears.!!! There
could be 2 S points difference in your report depending whether he is
listening to the left or right. All these anomalies should be declared
in a QSO.
