Phil,
Interesting topic. You refer to SDR as "software designed radio". Is it
not "software defined radio"? Not being picky here but just which one is the
correct one?

Subject: [TenTec] PO entroute to GE
About
20 years ago the move was afoot to migrate from something that was
indefinitely
fixable to, what was called at the time, "planned obsolescence".
That included
chips that would go out of production, using Lithium batteries
to hold memories
which when exhausted would render the device useless,
and fixed
'end of
support' dates after which any remaining parts would be destroyed.
Now, our
next "PO" generation is becoming "GE". The term "GE" refers to that
recent
money making idea forwarded by Monsanto -- Genetic Engineering.
For
those
unaware, Monsanto is a chemical company that modifies things like seeds
(wheat
corn, etc.) so they will germinate but they will NOT reproduce. The
result is that farmers need to PURCHASE NEW SEED every season. Seeds
can not
be carried forward.
Likewise the future crop of radios will employ fixed
internal program
expiration dates. The point being, in the not so distant
future, that you will
NOT BUY a radio, but you will only LEASE it for a fixed
period of
time. Leading
that line of reasoning are SDR's (software designed
radios). Currently
SDR's use
non-expiring source. (Stay tuned Microsoft fans)
On the horizon are SDR's that
require software/user validation to install along
with fixed licensing
that stipulates programmed expiration dates. Needless to
say these
will be
accompanied by the hacker community willing and able to
make your "radio last
longer".
Vacuum tubes anyone?
