GPS Monitoring for DRAWS

Edouard Lafargue
 

Hi everyone,

  Since the DRAWS is equipped with a GPS receiver, I figured I would write a quick web interface for it. I mostly use my Raspberry Pi station remotely from my Mac, and having a web interface to monitor the radio and GPS is fairly useful.

   I used the open source Wizkers.io framework to implement this, so that it works nicely with the remote rig control and monitoring that already exist for it (full disclosure, I am the developer). The code is not pushed to Github yet, but if there is interest, I'll be happy to oblige.

What other GPS information would you want to see on a status dashboard? The screenshots below are all web pages:

You might run afoul of one instance of Direwolf opening the ALSA device
for the sound card and locking out the second instance unless you do
some trickery in the ALSA configuration files to present the UDRC/DRAWS
as two separate audio interfaces.

This is doable of course, just may require a bit of research.

Re: Eureka!!!! She works perfectly!!

I found after my board was fixed by NWDR that DRAWS manger values were not even close to appropriate for using FLDIGI, particularly on receive.  I also had to recompile FLDIGI using configure defaults (using no parameters) before the audio settled down properly.  I find the receive audio to be quite good with an apparent low noise floor from the sound card.  Transmit audio seems fine as well. 

FLDIGI has a process for setting audio that always works well, so I suggest using that rather than arbitrary values computed by DRAWS Manager.

Appreciate all the info shared about this product!

I don't know about the FT-817, but my FT-857d works great with the latest DRAWS board using an un-modified 6-pin data cable (NO pins removed).  Just wanted to mention in case anyone with an FT-857d sees this post and wonders if they have to make any cable modifications.

However, direwolf, in addition to being the modem can support many functions without the need for the Linux AX.25 stack.  It can directly support digipeating, APRS®, Igating, beaconing (including GPS parsing), KISS, Network KISS/AGW, APRS® TouchTone™, and more.  All via configuration in direwolf.conf with fewer 'moving parts'. I consider it a simpler approach, if it meets your needs.

The choice is driven by application requirements and user preference.

I found that the Direwolf alone approach was easier for switching from AX.25 to HF modem function. I have to work at 'script-kiddie" level in Linux. I am busy with real work and I need to reconfigure it so very little that I have to go back and reference my notes (which are not great) each time I fire up. I would love to see an install choice be offered in the configuration scripts.

John, Basil, is that easily do-able without creating internal dissension or is it a philosophic divide you would rather not bridge?

No doubt there are good reasons for both approaches... however, I am a realist and know I will not get time to go "larval stage" with the OS until I retire, so as smooth and efficient as Basil's approach may be, it seems less flexible than having GUI access to Direwolf, being able to check its status and shut it down without bringing up a terminal or creating a bunch of icons linked to scripts that switch things for me. Typical lazy ham, I guess.

In the meantime I have a DRAWS in my "go-box" for portable digital work and one on the desk here running Xastir as a fill-in digi and inet gateway for local 144.39 users.

Thanks for these ideas everyone.  I’m just in the middle of setting up my DRAWS Pi with two radios, one doing APRS and the other running LinBPQ for a BBS.  Very interested to hear about APRX and LinFBB, neither of which I had heard of before.

I would also be interested to hear in the reasoning behind the two different philosophies, advantages and disadvantages.  I’m currently doing it all through Direwolf as that’s the only way I know how, but have been dipping my toes in to the AX.25 stack as I’ve been playing with LinBPQ.

So much to learn and so much to read.  I appreciate all the work done and would also appreciate any other resources regarding these two different methods of doing packet radio with a Raspberry Pi.

One of the things that I don’t understand is how an instance running on a raspberry pi with two changes knows how to route traffic from Channel 0 (ie 1200 baud )
to Channel 1 ( 9600 baud ).

See: 4.5 A Bi-Directional Cross-band Digipeater in this manual
https://thelifeofkenneth.com/aprx/aprx-manual.pdf

At our tower site, we have a pair of radios one on 145.610 and 147.555 and a Raspberry PI running a DRAWS with 2 channels.
Our State Packet Team insists on 145.610 running 1200baud, and only Digipeating, FBB Access and Winlink Client access.
For the tower site
KB9SZK-7 X.25
KB9SZK-10 Winlink RMS (Telnet access to WinLink CMS servers)
KB9SZK-1 APRS and FBB
The Tower site has a Sprint internet connection to provide APRS Server access and Winlink Telnet access.

At our EOC we are running 147.555, a HF rig for ARDOP access to Winlink, and a raspberry PI

For the EOC site 9600baud on 147.555
KB9SZK-8 X.25
KB9SZK-11 Winlink RMS (Telnet access to WinLink CMS servers or ARDOP access via HF if needed)
KB9SZK-2 APRS and FBB

Questions are:
How do we configure routing such that a station connecting on 145.610 at 1200baud, digipeats the packets on the 147.555 so that the the station can find the FBB server at the EOC.

Need more detailed explanation (maybe a diagram) of what you want to do. Just describe a
scenario. I believe Uronode will provide the functionality that you want.

How do we limit the Raspberry PI’s so that we don’t have APRS traffic on the 145.610 channel. ie the Tower Site Raspberry PI.

And then how do we configure the FBB that is in the build. Can we install FBB so messages are automatically copied from the EOC raspberry PI to the Tower Site Raspberry PI,

There are ways available to sync BBS's. I haven't done it but I know
it's possible.

Again Thanks!!!!

In a console run this:

You should see ax0, your first ax.25 channel on the left connector & ax1
the second ax.25 channel on the right connector.
You need to set the baud rate you want (9600) in /etc/direwolf.conf
under "Channel 1 Properties". Change the MODEM 1200 line to MODEM 9600.

By default the left & right channels are always configured so it
shouldn't be too difficult to get the second channel going. The hard
part is that 9600 baud packet requires you to set deviation more
precisely than 1200 baud packet. Having access to a service monitor
helps.

Let me know how you make out.

One of the things that I don’t understand is how an instance running on a raspberry pi with two changes knows how to route traffic from Channel 0 (ie 1200 baud )
to Channel 1 ( 9600 baud ).
See: 4.5 A Bi-Directional Cross-band Digipeater in this manual
https://thelifeofkenneth.com/aprx/aprx-manual.pdf

At our tower site, we have a pair of radios one on 145.610 and 147.555 and a Raspberry PI running a DRAWS with 2 channels.
Our State Packet Team insists on 145.610 running 1200baud, and only Digipeating, FBB Access and Winlink Client access.
For the tower site
KB9SZK-7 X.25
KB9SZK-10 Winlink RMS (Telnet access to WinLink CMS servers)
KB9SZK-1 APRS and FBB
The Tower site has a Sprint internet connection to provide APRS Server access and Winlink Telnet access.

At our EOC we are running 147.555, a HF rig for ARDOP access to Winlink, and a raspberry PI

For the EOC site 9600baud on 147.555
KB9SZK-8 X.25
KB9SZK-11 Winlink RMS (Telnet access to WinLink CMS servers or ARDOP access via HF if needed)
KB9SZK-2 APRS and FBB

Questions are:
How do we configure routing such that a station connecting on 145.610 at 1200baud, digipeats the packets on the 147.555 so that the the station can find the FBB server at the EOC.
Need more detailed explanation (maybe a diagram) of what you want to do. Just describe a
scenario. I believe Uronode will provide the functionality that you want.

How do we limit the Raspberry PI’s so that we don’t have APRS traffic on the 145.610 channel. ie the Tower Site Raspberry PI.

And then how do we configure the FBB that is in the build. Can we install FBB so messages are automatically copied from the EOC raspberry PI to the Tower Site Raspberry PI,
There are ways available to sync BBS's. I haven't done it but I know
it's possible.

Again Thanks!!!!
An Extra Thank you for your efforts. Most do not have any idea of how hard you have to work to keep up with the masses. :)

I think you want a second ax.25 channel, which should already be
configured.

In a console run this:

ifconfig
or
ip a show

You should see ax0, your first ax.25 channel on the left connector & ax1
the second ax.25 channel on the right connector.
You need to set the baud rate you want (9600) in /etc/direwolf.conf
under "Channel 1 Properties". Change the MODEM 1200 line to MODEM 9600.

By default the left & right channels are always configured so it
shouldn't be too difficult to get the second channel going. The hard
part is that 9600 baud packet requires you to set deviation more
precisely than 1200 baud packet. Having access to a service monitor
helps.

Let me know how you make out.

Our club has a DRAWS using a single radio that we have configured to
run as a digipeater and Winlink X.25 access using telnet to the CMS
servers.

The single radio is configured for 1200 baud X.25 Packet Digipeating
with access to a Winlink RMS. Our affiliation with the statewide
packet network limits that channel to 1200 baud digipeating and
Winlink X.25 access. They also exclude APRS data on that channel. We
can specify in the Winlink client a VIA to connect to another site
with HF access to Winlink.

We would like to add a second radio on the second DRAWS interface to
support 9600 baud, APRS Data and possibly a FBB instance.

Is there information on adding a second interface?

Re: Adding a second radio

Basil,

To take this one step further, can you add a HF rig as a second radio running ARDOP with the first radio running ax.25?

Thank you,
