Hi there all,<br>
I have a TT4 in the back of my car connected to a IC-1010, with a
home / witches brew volt volt cut out, it monitors the rear battery
and just turns off the TT4 and radio + GPS, in the program for the
TT4 I heavily use smart beaconing, setup right works well, then when
I stop for a long time it beacons a couple of times with-in the
first 20 minutes, and then if I have not moved after that there is
only 6 - 9 beacons per hour as it does not move, this works well in
my case, and then the battery slowly gets to the cut off point about
12.8 v then dead until I start the car.<br>
<br>
Now the TT4's do have a special feature in the software, just for
this sitting in one place not doing a thing, it looks at the GPS
sentence notes that it has not moved and swaps a pin high or low
cant remember, to find it you have to CLI into the TT4, it is also
tied up with the voltage set point, I know it is there got the
writer to install it.<br>
<br>
I feel a voltage drop out would do the job for him well, I have my
drop out set high otherwise you can hear it squawking at nights if
the volume is up on the radio, I have it set so I can just here it
whilst driving, its funny when you are driving around in the middle
of nowhere and all of a sudden you start hearing traffic.<br>
<br>
I hope this gives an idea,<br>
<br>
cheers all<br>
<br>
Paul<br>

Hi All,<br>
<br>
Corruption is commonplace in APRS.<br>
<br>
This morning, looking at VK2TGB-7 which has been stationary
for the<br>
entire 48 hour history in <a moz-do-not-send="true"
href="http://aprs.fi" target="_blank">aprs.fi</a> and has
beaconed every 2 minutes (yes,<br>
that is 2880 beacons for a station which did not move,
repeated by<br>
several digis into the Sydney region and until recently, gated
from<br>
APRS-IS back to RF by VK2ASY in Orange so that it travelled
back via<br>
Orange, Ginini and Illawarra/Southern Highlands digs to the
Sydney<br>
region again). Until Monday, I would hear each those posits 4
or 5<br>
times, so on average a VK2TGB-7 packet very 25-30s... if
VK2ASY ceases<br>
his gating of this stuff to RF, it is an average rate of one
posit every<br>
60s (via Vk2RHR-1 and VK2AMW-1)... and yes, for a stationary
tracker.<br>
<br>
But, one posit in those 2880 is interesting:<br>

<br>
The middle one is a most unlikey position change... exactly
one<br>
character in the MICE encoded position changed. If this
occurred in the<br>
AX.25 link, it should have been detected by bad CRC and
discarded... so<br>
it has happened in the tracker, or in the iGate / APRS-IS
infrastructure<br>
(and it is a single bit error in that case).<br>
<br>
I have noticed certain stations (including VK2MB) commonly
figure in<br>
corruptions whereas others don't so it points to those
stations as<br>
probable corrupters.<br>
<br>
Perhaps APRSdroid is the future, it bypasses all the problems
inherent<br>
in radio links and flawed digis and iGates!<br>
