Relatively speaking, how sensitive is the Tripmate?
I'm looking at using it sitting inside the car, where it will have an
admittedly compromised view of the sky. I have it sitting in place now,
and assuming it gets a lock, I'll try it over the next week or so, but I
thought maybe I'm beating a dying horse here.

You can already do this really easily with almost any client. Just connect
to a message only port and you won't be wasting bandwidth retrieving
station positions that you don't care about. You'll still get messages via
internet, but you won't be seeing positions. (except, perhaps, for
positions sent in association with a message)

I used to have a TripMate. Not bad. But not near as sensitive as the
Garmins I've had. (the 12, II+, III, and ETrex).
Big issue I found was battery power. I powered my TripMate from
the 'din' jack for the mouse on my laptop. That's 5vdc, fed up
to the thing from the 'RI' pin on the DB-9. I found I got MUCH
better performance when I made up a 6v regulator (right from the
car 12v) and fed that up to the unit. Be aware if you do that the
TripMates are known to self destruct somewhere around 8v or so.
I figured 6v as safe, as that's what I'd get from 4 brand new
alkaline AA cells.

Mine's getting 5V at the moment, from the vehicle supply.
I can boost it to 6V relatively easily.
Interesting mode of operating though, since there's no indication that it's
running, locked, unlocked, or whatever.

Hello everybody on the list,
I recently installed the aprs_status script on one of the IRLP nodes in
Eindhoven. I modified the script so the data it sends out is send to the
UDP port of the local APRS node. The APRS node and the IRLP node are
actually two machines sitting next to each other.
Everything seems to be working fine, in Xastir and UI-View32 I get the
object called STN8600 on the map when the aprs_status script is
executed. Untill a user of UI-View16 pointed out that the object that
appears on his map is called PI1EVH-5, wich is the APRSD callsign.
This is what the received frame containing the data looks like:
aprsvhf: fm PI1EHV-5 to APD215 via PI1EHV-2* WIDE2-2 ctl UI^
pid=F0(Text) len 64 11:09:49
}STN8600>APRS:!5126.94NI00529.21E0PHG3430.430100+71.9IDLE______
I tried changing the } to ; like when you send out an object from
UI-View. But this wouldn't help. Anybody any idea what's wrong?

Well, the only indication you could have that it was running would be to
hook a LED up to the rs232 data out. Watch the flickering patterns to know
if it's sending ASTRAL (1 / sec), or searching (very bursty and talking
about 25% of the time), or locked talking 75% of the time during each
second. I'm thinking a diode and a cap to feed the LED so that the LED
stays on during the $GP sentences and doesn't flicker with each
character/bit sent. Just make the time constant like 50 to 100ms. Then
the LED would stay on during the RS232 activity and it would be "humanly"
possible to determine what percentage of a second there was activity, which
in turn indicates lock - more data is published when it has a lock than
when it's searching the sky.

This is another in a series of off topic hit-and-run questions. It has
nothing to do with APRS, but the APRS community seems to have quite a
breadth of other experts, to I indulge Stan's patience and ask... but
request that replies go DIRECT, rather than to the list, please.
I use a web client for email. Is there a way to setup my client OS to
launch to my webmail website (with appropriate to: and subj: info added)
when I press a mailto: hyperlink? Thoughts and insights are appreciated.
Btw...please reply direct, not to list.
Kind regards,
Ev

To see the status of your Tripmate, I'd guess the easiest thing is to look
at your peripheral equipment: your TinyTrak, D700, Palm, laptop, etc. I
personally have been using a Tripmate for the last 2-3 years continuously
and with only a few problems, that mostly have to do with a slow locking
rate when the car has been in the garage for extended periods of time
(weeks). With normal, day-to-day use of the APRS tracker, the GPS locks
within 2-3 blocks driving (I'd estimate less than 3 minutes).
The 6 Volt power supply is a "well-known trick" to reduce initial locking
time of the Tripmate. Above mentioned experienced times are using 5 Volts.
My setup is as follows:
Tripmate:
- autostart modification
- added amplified external antenna
TinyTrak2:
- changed 78L05 to an 7805 to be able to power the Tripmate from the
same source
- built into Tripmate battery compartment
- brought the TX/RX/GPS/Power leds outside and wired them to mini-leds
that I mounted into a "blind" button on the dashboard
This is hooked up to a IC2AT and 35 Watt PA, and the complete 4-component
setup is "stored" under the rear seat of my VW Golf, completely out of
sight for anyone. The wires are discretely hidden under the car's rug...
The GPS Led of the TT2 gives me ample indication of the status of the
Tripmate: off = no signal received from the GPS (should only occur during
the 1st few seconds of startup, and while programming the TT2) Flashing =
valid NMEA data received from GPS, but no satellite lock yet Solid on = GPS
lock achieved

Today I meet up with WB2ZRV at a Truck Stop South of me.. But first as
he was coming towards my location he was putting out packets but WinAPRS
wasn't decoding them. So I went through his setting and discovered the
only thing set differently on his D700 was under Waypoints was set to 9
digits NMEA which is because he's running a Garmin 162 Chartplotter type
GPS unit in his rig. And it plots the stations received on the map of
this unit. But the main question why doesn't WinAPRS decode this type
packet. Below is one of his packets and one of mine. Which WinAPRS
decodes fine. Version of WAPRS is 2.7.2
WB2ZRV-14*>WIDE2-2>GATE>S9UP6W (UI):'q<%!fvu/]"75}TM-D700A
K9APR-9>WB2ZRV-14*>WIDE2-2>SY5Q0R (UI):'q4kl!9k/]"7K}
My Waypoint is set to off, and the GPS unit is a Garmin eTrek... I will
also note PocketAPRS showed him on the map fine...
