Still is the case now.

Agreed.

Well, the Internet leaves HF packet forwarding for dead under normal
conditions.  Why forward at 300 bps on an unreliable circuit when you can
forward at 256kbps ++++ reliably 24x7?

Which is true.  Spark had to go, because it is essentially incompatible with
where radio went.  Other modes such as AM and CW have persisted, because they
CAN still be used, and some (especially CW) have a lot to offer, even today -
CW's greatest asset is the "bang for buck" - no other mode is so effective,
when the effort to build a CW transmitter is considered.  An FM rig with a
broken mic could be used as the transmitter (Been done many times on the sats
:) ) in a pinch.

I'm certainly going to be keeping RF alive as long as I can manage (hopefully
several decades).

Ahh yes, but look from the other side of the coin.  While radio is the most
useful in the immediate area, we all know what HF propagation can be like, and
then there's the increasing urban noise, which makes it difficult for HF links
to operate in the cities, unless conditions are good (and if BPL enters the
scene.....).

Now, if we had a handful of strategically located HF systems, AWAY from the
disaster area, but within RF range, might that be useful?  Short of all out
nuclear war or widespread terrorist attacks, that should be of some use.  I
have already done the remote Net Control thing, it helps the locals do
something important during the night.... like catch up on sleep so they're
sharp the next day. :)

The key is knowing your systems, knowing the failure modes and having a
fallback position.  Radio can just as easily fail - I have seen 80m dead as a
dodo in evening prime time.  We had to fall back to VHF for a "HF club net"
once, using repeaters and some creative manual linking.  Echolink or IRLP were
only a step away next in line, but in that circumstance, they would have been
far more useful than HF.

I believe in having a range of tools to use.  Use them wisely and don't rely
too heavily on any single tool.
