measures. (LCD para 11A (2) )<o:p></o:p></span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial; color: navy;"><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial; color: navy;">First the
question to be asked is what Reasonable
measures (actions that the operator can be reasonably be expected to
take) has
the IGate operator taken to adhere to the LCD and prevent a
non-authorized
transmission from his / her station.<o:p></o:p></span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial; color: navy;"><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial; color: navy;">The answer
is that he/she has implemented
a Passcode system by means of the IGate / APRS-IS software that will
not allow
any inadvertent non-authorized transmission to emanate from their
station.<o:p></o:p></span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial; color: navy;">The Passcode
is considered an
international standard which is used throughout the APRS-IS network to
limit
inadvertent (accidental) RF access and as such should protect the IGate
owner
from regulation breaches.<o:p></o:p></span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial; color: navy;"><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial; color: navy;"><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial; color: navy;">The Second
question is; What is the intent
of the person generating the non-authorized transmission?<o:p></o:p></span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial; color: navy;"><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial; color: navy;">The answer;
It could be argued that the if
a non-authorized person goes to the trouble of finding, generating then
configuring a Passcode into an APRS application then the Intent of that
person
is to generate an non-authorized transmission and hence the onus is on
that
person, not the IGate operator.<o:p></o:p></span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial; color: navy;"><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial; color: navy;">It does not
matter that the generator of
the non-authorized transmission is or is not aware of the regulations
(sorry
officer I didn’t see the 60kmh sign), by their actions it was the
Intent
of that person to generate a transmission on the APRS network (the
network
consists of both APRS-IS and RF). Hence that person is accountable for
the non-authorized
transmission.<o:p></o:p></span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial; color: navy;"><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial; color: navy;"><o:p> </o:p></span></font></p>
<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial; color: navy;">For what
it’s worth the use of a Passcode
could be interpreted that the APRS network (both APRS-IS and RF) is a
non-public
transmission network carried over a public communications network. IE a
VPN or
in old packet terms a gateway tunnel. This would not however change the
Intent
of the person generating the non-authorized transmission.<o:p></o:p></span></font></p>

<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span

helpful.<o:p></o:p></span></font></p>

I-gate sysop, there
is only one way an F call will appear from the Internet to RF is if
they are
using a valid call pass, Now for those of us that use Linux the code
for such
is freely available and is distributed with both APRSD & XASTIR
(possibly
others) so for instance..<br>
<br>
callpass VK7FXXX<br>
Passcode for VK7FXXX is 4791<br>
<br>
Now there is nothing preventing any person Amateur or otherwise from
receiving
APRS data, but this is not the issue, it the transmission coming most
likely
from an iPhone/Android application or a PC. the F call in this instance
should
ONLY enter a call pass of -1 (or left blank if that is what the client
prefers)
<br>
<br>
There was much discussion a while back on the javAPRSSvr mailing list
(this is
the software used by the CORE & T2 servers and also by some I-Gate
sysops,
myself included) on developing a better way to authenticate a users
credentials, there was talk of using SSL certs but the maintenance
would be
horrendous! not to mention breaking compatibility with older APRS
clients like
UI-View etc... So this was soon knocked on the head as being to time
consuming to maintain and implement, after all this is a hobby not
on-line
banking!<br>
<br>
So my take on this is that whilst the LCD states what is does for each
grade of
licence, we are obliged to adhere to them, of course there will be a
minority
that won't but you get that with any rules & regs! <br>
<br>
I for one will not be implementing any such "filtering" to catch out
any possible breach of license, I only have the APRS spec ALIAS's set
and
that's for nogate/rfonly/nocall I certainly don't have the time to sit
and
monitor every packet that is transmitted within range of my I-Gate!<o:p></o:p></span></font></p>
