DRAWS viability

Patrick Bouldin KM5L
 

HI, a friend sent me a two year old youtube link on this topic. We are an EMCOM group in Texas looking for a solid solution for Winlink. We want a solution that is cost-effective, but also hardened so that the majority of users don't have to be linux admins, if you know what I mean. Is this viable for that purpose?  Other than this group, I don't see a lot of chatter on the web for it, just here and there.

If this is viable, has anyone written a KISS document for jump starting? 

73,

I was able to use the file as mentioned from Bryan to have three digipeaters working for the AYCE bike event this weekend.  I do like knowing what port to use. It simplifies things so others that helped could to put together two portable digipeaters we used this Saturday.  The event went very well and we were able to see the SAG vehicles running around the course.  The draws board with GPS and GPSD running, PTT with audio is a nice robust way to a build portable Digipeater.

Ed,
After re-reading your question, John's answer is the correct one.
Type: man call
for more info.
Eg. To log into a node or BBS:
call udr0 <some_callsign>

You don't have to worry about channel jamming because your event can use a non-standard frequency for your APRS network. Every bicycle event I have worked has _never_ used the national APRS frequency for their support vehicle tracking.

Most desktop APRS applications can keep track of incoming APRS text messages, and the radios with built-in APRS support can (painfully) send text messages from their keypad.

So your Net Control station watching APRS position reports should be able to see texts from your field stations easily enough.

Just a suggestion.

Sourceforge project UIChat v 1.07 is a Linux (RPi) based AX.25 Bash
command line utility to send UI messages between stations with optional
digipeaters.

Version 2.0 is now defunct, because the source code was lost and I don't
want to recreate it. :)

Sorry for the lag. I'm traveling.
There are quite a few AX.25 apps that will do peer-to-peer packet.
For 1 to 1 I use chattervox and for 1 to many I use APRS messaging as found in Xastir, YAAC or nixtracker. Try some out to find the one you like best.

Local Peer to Peer has only been tested once and still needs to be

Some of us tried to use old fashioned Peer to Peer Packet recently while
supporting a 100 mile Ultra marathon. I did not participate due to a
vacation so I did not attend the training session.

What do I need to do with my Pi to be able to connect to a Peer, "log
in", drop a test string or file with data (bib number, check point, time
in, time out), "log out" and close the connection so others may do so?

UDRC-II power jumper

Erik Nelson
 

Hi all,

I'm attempting to change over from powering the Pi off UDRC 12 volts, to powering the Pi separately to allow D-Star to be turned off on the repeater. I'm unsure of which jumper changes over from 12v to 5v, any help is appreciated.

Re: Direwolf APRS Callsign

Basil Gunn
 

You already proved direwolf ports were set properly when you used btest.sh script. Initial direwolf config sets up both direwolf ports 0 & 1 (left & right). Your problem is not with how direwolf ports are configured. I suggest you put that config back the way it was initially & read the direwolf manual on how to beacon ... or just use the btest.sh script.

The file is position sensitive everything after channel 0 applies to the left port until you get to channel 1

Re: Direwolf APRS Callsign

 

GPIO 12 is for Channel. 0 which is the left port
GPIO 23 is for Channel 1 which is the right port
