Floyd claims to have measured microwave paths for 40 years. I`ve been
doing it since 1960, so that`s about as long.
I`ve made repeated measurements over a number of years on the same
repeaters. During normal propagation, which is by far most of the time,
path loss like other system losses is very constant.
Of course there are periods of anomalous propagation. It depends on
location, season, and time of day. It`s worse when the atmosphere is
stagnant.
So now you say it's constant except for when it's not! Your designs
are within 1 dB except when they aren't.
I *am* impressed.
I`m sure that marginal paths with insufficient clearance and other
problems may have propagation which comes and goes. I`ve seen some, but
I haven`t built any like that.
That's why I asked if you'd built many.
In fact it is quit common, and most paths have anomalies. Most of
course aren't very interesting. But others are. Suggesting your
designs have never collided with such an anomaly just means you
either didn't really do many or you're failing to recall them.
