What are you going to use when HF propagation is too weak to support
voice???

Dee D. Flint, N8UZE



1. Change frequency.
2. Use relaying to get messages through. (After all isn't that we
supposedly train for, as well as one of the principles of the Nation

Traffic
System??

Nowhere is it said that in an emergency that the message MUST make it in

ONE
"hop." (i.e. no relaying) I am quite sure that message traffic from larger
incidents like the big earthquake in California quite a few years ago

didn't
make it out of the area in within just one hop. (The traffic being sent
around the country that is)

If HF isn't supporting voice propagation, to what frequency would you
suggest changing? Oh yeah, VHF/UHF when you're too far out to reach
anybody. Right. Disasters don't just happen in only in areas small enough
where you can relay out. If some of the island nations (or states like
Hawaii) get hard hit, say by a hurricane, your only chance may very well be
HF.

VHF/UHF is fine for short distances but if the next active station is over
20 or 30 miles away, there is often very little chance of a relay. Many
islands are far more than 20 or 30 miles from the next nearest inhabited
land mass. On the other hand, with HF, one can reach hundreds of miles even
with minimal antennas. This gives you a chance to set up a relay. But if
propagation is poor, voice may not be intelligible yet CW will often come
through quite clearly under those conditions.
