[Dxspider-support] [Cluster-tech] PC92 A

[Lee Sawkins]

Hi Dirk.

I believe you are wrong about CLX and PC61.  I have been using PC61 for
several years now.  We discussed this at one time.  The PC61 is used by
CC Clusters to carry two digits after the decimal point for DX Spots. 
To change a PC61 to a PC11 is easy.  Just remove the IP address and move
the hops and the "~" character over one position.  Round off the
frequency.  

I can give you some numbers.  Not exactly PC92A, but general PC92s.

In the last 150 hours VE7CC-1 cluster has accepted the following unique
data statements.

DX Spots   27,780
Announces     413
PC92      196,950
PC93        2,470

Some announces were in the PC93 spots.  They got counted twice.

The overhead to DX Spots is almost 8 to one.

DX Spots average about 5k per day, except during contests, when they go
way up.  Oct 24 29,600 spots, Oct 25 34,000.  Users increase over 50%
and stay connected longer during contests.  So the PC92 go way up as
well.  I don't have the exact numbers.
