Thanks. Good points on the ALTNETS:
and I'm not sure that all client software does it all. ANd good point on
the NMEA trackers. APRSdos solves it by passing all Mic-E's and NMEA when
in SPECIAL mode. But it still ignores all other stations unless they have
SPCL as an ALTNET...

Actually, a perhaps better option for IGates is to connect to the APRS2
Tier 2 network. Consider whether or not your IGate really needs a full
APRS feed? Is your IGate an aprsD setup that is not connected to any
mapping output? Then connect to port 1314, which passes messages only (and
posits relevant to IGated packets). Both the core servers and the Tier 2
servers offer this port. And if your IGate is connected using a server
that supports mapping, consider using one of the filtered Tier 2 ports,
such as 14580. You do not need to connect to a full feed to be a
full-service IGate! Pete Loveall has written the javAPRSSrvr software so
that IGates will still pass messages received worldwide to those clients
listed in their IGate software's local list. So cut down on your
bandwidth! Very few people need to connect to the full feed! If we let
the core servers handle Tier 2 connections, and get the clients on Tier 2,
chances are the APRS-IS will be a much more stable network. Bottom line -
wherever you connect, to the core or to the Tier 2 network or wherever,
stop and consider if a full feed is necessary for your operations.
Thanks!

Couldn't agree more.
Full feeds -truely- are not needed for IGates with the filtered igate ports.
All but first of the core servers offer this, and all of the tier 2 servers
do.

What's available now for sending and receiving APRS text messages while
mobile? Don't the Kenwoods have a keypad entry mode?
I was thinking about possible featuers for my new project last night, and it
occured to me that it'd be fairly simple to provide an AT/PS2 keyboard
interface. Since the device already has LCD support, you could conceivably
use it to send and receive text messages. Of course, a full size keyboard
would be way bigger than the TNC, but at least it wouldn't take much power.
And there are some small keyboards out there.
Would there be any interest in this sort of setup?
The OpenTracker could be connected to a keyboard too, but you'd be typing
blind. Or you could make a keyboard-to-CW keyer that way. Not sure what
good that'd be...

Um yes. A google search of "Kenwood D700 Keyboard" is also revealing
(thanks again John!)

And there are some nice rubber ones that will stay put on the dashboard so
that you can type and watch the road at the same time.

Folks,
With this topic floating about, I think it's time for my annual "lecture"
about "air-bags".
These "safety" devices, subject for off line debate, are required in most
vehicles made for the N.A. market.
The selling dealer is under no obligation to tell you how this things work,
but by law must tell you how they work, *if* you ask.
Your service manager, will show you drawings of where it's safe to mount
radios, GPS units and now "rubber" keyboards (?) on or near the dashboard.
Until you *know* what's safe and what's not, do not mount nor place
*anything* on or near the dashboard ! In the case of an "impact", should
any of the air-bags "deploy" these could become deadly objects.
In Canada, these "devices" are optional, as one must use seat belts when
using H.R.H.'s roads anywhere in Canada. Personally, I have reviewed the
facts, and seen them "deploy" .... and heard them. In my case, on balance,
I have decided to have them removed or disabled from my vehicles, and that
of my wife's.
I do not think things are so easy in the U.S.. So ask your Service Manger
to tell you how they work, and where it's safe to mount all your gear.
My vy 73 to all the group,

Connecting to message only or filtered ports of either core or tier 2
servers does make sense for many, if not most, IGates. However,
multiple outbound connections, be it directly to core servers and/or to
lower level servers, will ultimately result in unnecessary duplicate
packets at the core. The point of this thread is not to direct where
stations make their connections, but rather to recommend that outbound
connections be made in an educated and considerate manner.
