[RTTY] ARRL Symbol rate proposal

[Kai]

How many DXers are there in the world?

We might take a stab at "HF active hams" by looking at LOTW published figures. 
Today's snap shot: of LOTW:
The average QSL rate is 2x76,455,901/525,115,672 = 0.291.  There are 60,341 LOTW 
users, so the
population of all DXers (members and non-members) must be around 60,341/0.291 = 
207,000 hams.
Slightly more than half of the LOTW users are in the USA, the rest are DX 
(HB9BZA stats).

So, assuming that the LOTW users and the QSOs they had with non-LOTW users 
represent mostly hams
interested in HF and DX, the population of HF/DX hams must be around 207,000 
world wide, and perhaps
slightly more than half of those are in the USA.
eQSL claims 219,000 uniques "users", another similar number stab at the DX 
population.
Some DXpeditions rack up 100,000 unique calls.

There are perhaps 2,800,000 hams on the planet, thus only about 7 to 8% are 
"DX/HF active.
Many (most?) of these DXers use RTTY, but a smaller number are dedicated RTTY 
contesters. Someone
on this reflector would have a good number for that.

I'm pretty confident about these numbers (+/- a dB or two), but I'm not sure how 
this relates to our symbol rate debate.
