Its actually quite challenging from an operational standpoint.  The
activity page on wsprnet is very poor.  Sometimes it is slow to update and
sometimes stations with low TX cycle never show up at all.  When you add to
this harmonic decodes which complicate the reported freq average (I had a
large number last night due to wet local condx) the numbers reported for
frequency are not worth very much.  And most of us do a batch review of the
previous session the day after unless we are explicitly using WSPR to seek
QSO conditions so we don't often know if there is co-location unless we are
told during the session.

There are also numerous obstacles in the passband, carriers from plasmas
that cause people to make minor shifts and one prolific wideband pair
around .635 spanning to at least .645 that is worldwide 24/7.

If you add frequency instability, which I have due to shack temp variations
and an exciter that cant be GPS locked, it only adds to the chaos.

The passband is getting busy, guys sometimes move not realizing they are
moving too close to people.  A month or so ago one station made a 10 hz
move and it forced a major readjustment for everyone.. Its a good problem
to have and it will only get worse as more stations come online.

73!
