Default Why digital modes are few used

Data transmitted over Amateur Packet Radio is not permitted to be
encrypted.


Larry.... it is "encrypted" in a sense. Otherwise my scanner should be able
to recieve it no different than the voice comm's I already hear there. It
is "encrypted" (or maybe a better choice of words being "encoded") in the
sense that it needs to be encoded before sending over the air and decoded at
the other end. And this is totally legal as long as the standards and such
are publicized. Look at PSK31 and the 15-20+ other variations of the
digital modes, are you now saying all of those modes are illegal?

When was the last time you listened to a packet signal being transmitted and
could tell what was being sent as far as the content of the message, merely
by listening by ear? If you are that good, you have my respect, as it
merely sounds like a digital "blurb" to me.

Now do you understand what I meant by "encrypted?" The average "public" in
"scannerland" does not have the capability to monitor that traffic as we do.

Injuries,
triage info, fatalities are information that *may* have to be passed as
traffic and need to stay in a mode that is not generally accessable to

every
nut (or media person) with a scanner. Packet, albeit slow is okay for

this,
as it is a legal means of encrypting the data.


Ryan:

Data transmitted over Amateur Packet Radio is not permitted to be
encrypted. Equipment to receive and decode AX.25 packet radio is
widely available, even to the news media, so that is not what I would
consider to be a legitimate concern. Any mode used by hams to
transmit data over the air must be considered to be wide open to
monitoring by anyone capable of acquiring the off-the-shelf technology
necessary to receive it.
