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.

Joe will say that that can't be compared because there's a much higher ham
population in the US.
But how many are really active on HF?

Betreff: Re: [RTTY] ARRL Symbol rate proposal
I'd be up for a petition type thing, however, I'm not sure signatures from out
of the country would hold much weight, perhaps some comments from groups such
as the RSGB or DARC or other countries amateur radio groups would carry more
weight....

By the way, let me float this to the RTTY community -- do you prefer that
we submit individual comments to the FCC, or do you prefer that we
together draft out something for interested parties to sign (and tout their
own credentials, if need be).
I know that there is already at least one effort to collect as much
documentation as possible to counter
ARRL's lame idea. I have been in the CC of emails of such activity, and have
also participated in the private discussions.
If a collective, well thought out comment is publish before any FCC deadline,
would you prefer to sign that instead of submitting your own?
I have not floated this idea to anyone yet, I am interested in what the
community prefers, and we'll
see if the folks who are already drafting a comment (let's call them "the usual
suspects" of RTTY HI HI) would be willing to let others add their names.
BTW, the signatures do not have to be limited US licensed hams, since QRM can
travel far and wide and affect everybody, including SWL.
