Raspberry Pi has sufficient computing for the applications we are designing for and there are millions of them deployed. They are inexpensive and have active development and community.

Our development and support costs go up with more platforms.

We are going to offer the DRAWS as a complete and integrated unit to drop into a station, at which point the SBC is just a part of the solution. We prefer to focus our efforts on this

Nice product, why not make the little unit compatible with other SBCs other than Rasberry Pi?  Maybe an added usb port to interface would make the unit interface with many SBCs and making sales go up even more?

DRAWS: Schematics and further details

Hi,

I recently found this project and immediately ordered a DRAWS hat, as it firs exactly to my use case. I just have to plug it into my TS-480SAT and there I'll go. The only thing missing is the connection to my Pactor modem, but at least I have still something to do...

While I'm waiting on the parcel, I can already read a little bit of documentation, I thought. But I do not find any schematic or at least a documentation of the chips used in order to see what is possibkkle with this kit. I would like to use it as a HAM enthusiast, so I do not want just "plug'n'play", I want to tweak a little bit, in HW and SW.

Maybe somebody can help me to find infos I need. Is it worth to look what's available for the UDRC as this kit is an extension thereof?

Re: Pi 3b to 3b+?

Hi Annaliese,

Following your indications did not make it, as kernel headers version was reported missing for the last kernel 4.14.69.
I had however a success after doing apt-get remove raspberry-kernel-headers then apt autoremove and then apt-get install raspberry-kernel-header
After that apt-get install udrc-dkms successfully built the module for present kernel.
After reboot, udrc module was listed with lsmod and aplay -l could find udrc card.
Many thanks for providing such a convenient way for upgrading udrc module following a kernel change.

You are on the wrong distro on both Compass and Rasbian. These are very rough instructions, but should work okay.

1) In /etc/apt/sources.list.d/raspi.list, change the word “jessie” to “stretch” wherever you see it.
2) In /etc/apt/sources.list, change the word “jessie” to “stretch” wherever you see it.
3) In /etc/apt/sources.list.d/compass.list change the word “alder” to “cedar”
4) Remove the file /etc/apt/preferences.d/compass
5) Execute the command “apt-get update”
6) Execute the command “apt-get dist-upgrade”

This should update your older distro to the newest Stretch based image that will have the proper firmware to boot a Raspberry Pi 3B+. Note that I have *not* tested this and that this procedure is from memory.

Check that rmsgw_aci is being run twice an hour.

First check that user rmsgw exists

id -u rmsgw

yes, it's 1001 on my machine 

Now check that user rmsgw has a crontab entry for rmsgw_aci

As root:
crontab -u rmsgw -l

It should look something like this:

# m h  dom mon dow   command
17,46 * * * * /usr/local/bin/rmsgw_aci > /dev/null 2>&1

yes it looks exactly like this. 

If there is no entry then as root add the line above:

crontab -u rmsgw -e

The first 2 numbers can be anything in the range 0-59 and should be
around 30 minutes apart. The above line reads: execute rmsgw_aci at 17
minutes & 46 minutes past the hour.

You can test your new rmschanstat script by typing:

rmschanstat ax25 udr1 NX2I-10

You should see something like this:
channel udr1 with callsign NX2I-10 on interface ax1 up

The script is picky about case of your callsign so be sure it's upper
case.

The rmsgw_aci C program calls the rmschanstat bash script.
Now try testing rmsgw_aci.

To fix that you may have to run this:

sudo -u rmsgw /usr/bin/python /etc/rmsgw/updatechannel.py -d

You also may have to get rid of the the extra channels.xml~ files.
rmsgw_aci maybe having problems parsing the correct file name.

Re: IP Addresses on 44.x.x.x. Was: [udrc] winlink client immediately disconnects from server

 

Hi Basil,

Net-44 IP addresses are for doing routed IP (whether RF or over the Internet) as they are fully routeable addresses meant for networking.  If one is staying on the localhost, then using the block 127.0.0.0/8 (sans 127.0.0.1) would work as that is the loopback network, which is sometimes used for other functions within a router.  Certainly any RFC1918 address blocks could be used on host and on LAN.  They are in the ranges

10.0.0.0 - 10.255.255.255 /8
172.16..0.0 - 172.31.255.255 /12
192.168.0.0 - 192.168.255.25 /16

Routers will discard these addresses on the public Internet.  However, 44.0.0.0 - 44.255.255.255 will be routed to UCSD (or a subnet that is advertised on the Internet, e.g. 44.24.135.0/8, which goes to a VPN server for redistribution). So if the Raspberry Pi has an Internet connection, these addresses could be creating unnecessary traffic on the network.  (Try some traceroutes and see what happens.

A good article on various net ranges is at https://en.wikipedia.org/wiki/Reserved_IP_addresses.

So best practices would be to use an RFC1918 or loopback if not connected to the Internet,  one of the "Documentation" reserved addresses for documentation and examples (See wikipedia article), registered NET-44 for RF/Internet for amateur radio traffic to save network confusion.  However, as I said, his current configuration is not particularly harmful depending on the rest of his network. 

When 44.24.197.0/24 is allocated, one could end up with address duplication, for example if routing to a Winlink on an address in that subnet.

kissattach requires a dummy ip address that is not used and that's what

If John H. could recommend a better dummy address that be good.
