We have all noted (those of us that have been aroud for a while) the
decline in amateur activity in recent years but is it REALLY declined ?
Like everything the world has ever known - it has a big peak but for the
rest of the time it has it's normality.
I cannot relate too long ago, perhaps about 20yrs worth but I can't help
but feel that we are all judging our hobby by the extroardinary levels
set by the early 1980's.
This brings me to a technical question.
How does one measure band occupancy ?
On one hand, we twiddle our vfo's for 5 minutes and if we don't hear
anything we pronounce the bands as dead.
We could look at a spectrum analyzer and see the band full of signals
but it may be for only a short period of time.
So is there a more academic and scientific way of measuring with values
band occupancy and levels to a defined standard ?
