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 size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>The Passcode is considered an
international standard which is used throughout the APRS-IS network to limit

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;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 size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;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 size=2 color=navy face=Arial><span style='font-size:
10.0pt;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>

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>
