[aprssig] Mobile Digis (New -N Paradigm)

We should add this recommendation formally to the
New-N Paradigm. This will go a long way towards
common and consistent use of pocket trackers and
other temporary applications:
D700 user's should be aware of these settings:
Set APRS-DIGI OFF!
DIGIPEATING A POCKET TRACKER:
Set Tracket to 144.99
Set D700 band B to RX 144.99
Set D700 band A to TX 144.39
Set D700 TNC to RX B & TX A
Set RADIO-TNC-DCD to both A&B
Set APRS-UIDIGI to TEMP,WIDE1-1
Save in a PM just for this application
Set pocket tracker to use path VIA WIDE1-1,WIDE2-1
This will make the pocket tracker use the the full
power of the D700 and with courteous channel
sharing AND with no interference or congestion
between the tracker and your mobile. Notice that
setting DCD to both is generally not a good idea
for normal operation because it will keep your
normal posits from going out if you are using band
B. So that is why this should be in a PM all its
own only used for digipeating the tracker.
ADDITIONAL SETTINGS using a PC:
Set UITRACE TEMP,30
This will cause your D700 to ALWAYS be ready at
any time to act as a temproary digipeater in support
of TEMPn-N routing. SUch as FieldDay.
The question is whether this is saved in APRS mode
or only in packet mode. And if you set it while in a
PM, can it be saved there too? I suspect this only
works in PACKET mode but that is fine for Field Day
or any other temporary net you want to set up.
RESULT OF TEMP mode:
You can use TEMP or WIDE1-1 to digipeat thorugh any
mobile that is in APRS mode and has APRS-MENU-DIGI ON.
And you can use TEMP7-7 as a path for Field Day
via any D700 that is in packet mode or any other time.
Once we all agree to this or some other arrangement,
lets get EVERYONE on board. We can easily
send a MESSAGE to ALL D700 users by simply using
the GROUP MESSAGE function. All of the Kenwoods
come with the default MESSAGE group of KWD.
Until we get the word out, a good message might be
To: KWD: See new-N settings for D700. Google XXXXXXX
and after we get everyone to a consistent set, then for
special events where you need an instant net on
a different freq for emergency or special comms then:
To: KWD: SPECIAL, pse support alt-net on 145.01 TNX
or any other uses.. But we need owners to be fully
awayre of the potential of their radios, how to set
them up, and how to use them. THus, I want us all to
debate the final settings for digipeating and agree and
then include it in the New-N pparadigm so that APRS
works consistently everywhere and is flexible and can
respond quickly to emergent needs.

No, because the special path of WIDE1-1 is for
use by home and fill-in digis only. So better to
use the path of GATE,WIDE2-1. It is still only
a 1 hop path but does not key up home stations.

Yes, set your D700 to digipeat by using a PC to enable
its UITRACE parameter with the permanent alias of
TEMPn-N. This way, any mobile any time can be used
as a temporary digi, but all the other time, the digi does
not digipeat any normal on-air packets and so does not
add any problems. But is always available.
