Notice I said "Visible". I will not argue on who is most
active. When you attend a hamfest there is almost always a Satellite
Booth or demo. Amsat has become a very large and "visible" group
both for hams and for the public. Certainly the Emcomm activity of
ham radio gets the most press (and perhaps it should). But within
the bounds of the technical side of ham radio satellite still ranks
with high numbers of visibility (at lot due to ARISS).
Other areas of interest probably are more active right now...that
ought to be a wake up to the satellite segment. When I say satellite
"should" rank that is also commenting that perhaps it isn't curently
measuring up (most of the innovation is being done at the
organizational level and not in the shacks of the average satellite
operator - oh boy!
now I have probably steps on alot folks pride - but think about how
much construction is done? - other than hooking up cables and installing sw).
I am into microwave, eme, sdr's, radio astronomy...and lately into
500-KHz. All these activites require basic building and testing, as
that is (about) the only way you will get stuff for these areas of
interest. The Leo sats (FM voice) does not require much more than
the HT or mobile radio to get on. Satellite tracking hardware
abounds and is pretty easy to install. Digital satellite is probably
much more technical and requires a bit more in the manner of putting
together a system.
Now I am not saying that this is a bad thing, but as an area of
"technical" advance in ham radio it is left to the satellite builders
,in the main. The technical contributions are coming from other
technical areas of interest and being applied to satellites (e.g. GPS
diciplined local oscillators and SDX). The computer control system
is largely not an activity that the average satellite user is active
in (its a few specialist on the satellite developer's team and draw
from areas like TAPR, etc.).
So I don't think we are in disagreement (significantly) ;-)
