In this country we have had a long tradition of very reliable power
generation and distribution (so reliable it makes hardly any sense to
install UPS equipment except for really critical equipment), water quality
has been so good that you can just drink water out of the tap, the
telephony system has been working fully automatically (no operator required
for any national call) since the fifties, a very dense railroad network
has provided service even in areas where that is not profitable, etc.
This has all been established without any competition and at very good
prices.
Now, the EU requires us to open these markets for competition. This
has resulted in lots of extra efforts by the existing companies that had
not been structured in a way to support multi-access to the infrastructures
they manage, and also in a lot of rework on the infrastructure itself.
So what do we have now? The railroad company has been split into
infrastructure and operating companies, had to raise tariffs to allow that,
a "mickey-mouse" 2nd operating company was introduced and has already
terminated its services. So we are left with just the costs.
The mobile phone market is now services by 5 different networks (and even
more "service providers" operating on those networks). Antennas are
popping up literally everywhere, not a pretty sight both in urban and rural
environments. It has become nearly impossible to select a good deal.
The phone company had to make difficult "interconnect" arrangements and
technical modifications, and therefore could not properly service its
regular customers for a long period of time. And when it (KPN) wants to
introduce some new service it first has to wait until the competitors can
offer it as well... thus, competition is hampering progress.
The local electricity company is being sold to an American company. I hope
this does not mean they will adjust the quality to American standards!
Who knows what will happen with the water and gas, but looking at what
happened it GB does not promise much good...
Don't tell me "the prices will drop because of competition". They haven't.
You a probably mistaking price drops in telecom (etc) as being cause by
competition, where they in fact are made possible by advances in technology
that would have taken place anyway. It has just become cheaper to build
and maintain a switch and its interconnections, that has nothing to do
with competition.

Yes, I couldn't agree more, Steve, with your assessment. When a LandLine Lid
takes traffic intended for the Ham digital network and routes it over
non-ham links instead, he in effect tells the packet users who originated
that traffic, " I won't allow you to use Ham Radio to communicate".
This is what TPRS did under Greg Jones' watch, and what TAPR is advocating
now.
Those who want to limit Ham radio, will destroy the hobby.
That's why we need protective legislation to eliminate this limitation from
the US digital network, once and for all.

Ok, so I can use a modem if I have the software, or a dedicated TNC for
packet. What would be the lowest cost way of getting into packet then?
I would like to eventually get into packet operation, but I fear that
