More SO vs SOA

The problem with the inflationary process of SO becoming the 'snickered at /
down at the heels / poor relation'  to high dollar, big gun SOA,  is that it
places severe financial and location barriers in the way of the vast majority
of contesters... If you are not affluent AND living in a heavily populated
part of the country with rapid packet spotting, you are a potted plant...
I recognize that it is fun for those who meet both of the criteria, but it is
further driving contesting into the haves and have nots..... This is not good
for the future of contesting...I strongly suggest that we look at what we are
doing to the sport...

The multi single / multi, multi  /  big production efforts, (al. la. W3LRL,
etc.) are fine and should not be criticized, because if you aspire to run
with this pack you KNOW that you had better be a big dog, or get back under
the porch.... They are fun to watch, and fun to work, and they are good for
the sport....

But, when a good, single op, contester discovers that he is $15K and 500
miles short of EVER having any chance of moving into the top ten, even once -
and, as a result loses interest - it injures the sport....
>From my point of view, the SO class should be 'single op' and 'single rig',
and a BUNCH of awards / attention / back patting should be available to
foster interest in this level of serious contesting...Will a few cheat? OF
course.... But, it gives us that front porch for new contesters to come
knocking at the door....and some will stay to become the competition to
Frank, et. al...which is what we need...

Cheers ... Denny    - nipping at the heels of the pack, arf arf....

Due to company mergers my email address has changed.  I am sorry for any
mail that has bounced in the last week or so, but we poor vax mail users
were forgotten when they changed addresses on all the other networks.

Please change   ROBBINS at GUID2.DNET.GE.COM 
in any of your mail distribution lists.

I think I have fixed all the lists I am on, if you see any bounced mail
from my old address after this message please let me know.

Subject: max length of RS-232 network link?

>>The maximum length of the RS-232 runs is not affected by the fact the

I posted this info on the ct reflector because that's where I thought
the discussion was taking place.  Please forgive the duplication here.
