<< Don't these improvements interest anyone in this group? Why are they so "alien", new and threatening to the amateur community? Actually, they're "new" only in the context of the amateur service, having long ago become standard practices in the non-amateur outside world in which we are becoming increasingly irrelevant.

Example: at the recent AMSAT meeting I met a recently licensed ham who has worked in commercial satellite communications for some time. In private, this person expressed shock at the primitive, brute-force approach that prevails in the amateur service. Slow data rates. Poor reliability. Ridiculously large antennas and RF power outputs. Little, if any, reuse of spectrum. Very little, if any, careful system design in evidence. Just what are we doing to justify our allocations, this person wondered. >>

We are not building commercial communications systems. If TAPR wants to build exceedingly slow immitations of the internet on ham radio, fine. But dont expect all of us to have any interest in such activities.

If weak signal ops had the reliability that commercial networks require, they would probably grow bored and find a new hobby. Apparently you have never been a Dx'er. We find value in weak signal work because it is difficult. If we had computers linking and communicating below our ability to hear, what would be the satisfaction of that? At what point do you just set the computers up at each end to make contact and then send out QSL's.

If your friend is concerned about justifying allocations, what about unattended HF packet. Talk about slow data rates! The biggest waste of spectrum I can imagine. Hey guys if you want reliabilty so much why not put all the traffic now on HF packet over your satellite gateway or God forbid, landlines.
