Lcd Display on a PI

After a busy period, I finally have a bit  “Me Time” again.

David KI6ZHD (drache), has written a fantastic article about setting up and configuring a RaspBerry PI. This article also contains a piece about setting up an LCD display at the GPIO port of the Raspberry PI.

This can be read here.

I have ordered a 20×4 LCD display and an I2C LCD interface on the internet.The price was $ 14.96 including shipping costs. Nice.

Take the time to read this good article.

Update start script

I have update the start script for pi1lap/pi8lap. I have add start/stop/restart/status in it.
The disadvantage of this script is if you for example make an adjustment in axport you have to stop and restart the whole system. Maybe divide into smaller parts.

Ok lets check the status.

Now let start the system.

Now look at the status

Here you see that “mkiss” is down. That is because I do not use “mkiss” at the moment.

Ok, now we will stop the system

Here you see that stopping has failed, this is because “mkiss” can not be stopped.

Here is the start script

 

Update RMSGateway 2.5.0.0

Finally i found some time to update the RMSGateway to RMS 2.5.0.0 with Winlink V5 CMS Web Services support. I only found the issue that if have to edit the sysop.xml and add the password. I dont have read that anywhere.

Thanks to /Basil n7nix we are good to go again.

More then 50 People of the 72 needs to update there software.

Instructions on how to update RMSGateway

Instructions on how to update to the latest scripts supporting Winlink
V5 CMS Web Services.

You need to complete this update soon as Winlink is switching its Web
Services over to only support their latest version. Note that no C
files changed for this upgrade just python scripts & the
/etc/rmsgw/hosts file.

First check your python version:

python –version

The new scripts have a requirement of python version 2.7.9 or above.
If you are running a Debian distribution then wheezy will not work,
jessie, stretch & sid are OK.

Second check that you have an /etc/rmsgw/sysop.xml file.

If you don’t have a sysop.xml file then read the admin/README.md file
https://github.com/nwdigitalradio/rmsgw/blob/master/admin/README.md

Note that the getsysop.py & mksysop.py scripts currently do not work
for the new Winlink Web Services because the SysopGet web service is
not enabled for our key. This may change in the future. If you do not
have a sysop.xml file you can use mksysop.py BEFORE you do the update.

If your system passed the python version test then you can easily
upgrade like this:

git clone https://github.com/nwdigitalradio/rmsgw
cd rmsgw/admin
# become root & run this command
…/admin-update.sh

Verify that the update is working

# As root run the test script in the admin directory

…/testwlapi.sh

# Search the log file for any errors
# The log file grabs some of the rms.debug log file and you are only
# concerned with errors found after you ran the test script

grep -i error /root/tmp/debuglog.txt

Now go to winlink.org (https://winlink.org/RMSChannels) and look at
the Winlink Packet RMS Map/RMS List/Gateway Versions sections.
Search for your call sign.

For more information read the README.md file in the rmsgw/admin
directory here:
https://github.com/nwdigitalradio/rmsgw/blob/master/admin/README.md

Systemd RestartSec/StartLimitInterval/StartLimitIntervalSec

Systemd

The default delay between executions is 100ms (RestartSec) which causes the rate limit to be reached very fast.

Just using Restart and RestartSec is not enough: systemd services have start rate limiting enabled by default. If service is started more than StartLimitBurst times in StartLimitInterval/StartLimitIntervalSec seconds is it not permitted to start any more.

Add RestartSec=5 in the service section
Add StartLimitInterval=0 in the unit section

Run

 

 

RMSGateway New version

There is a new version of RMSGateway. This is at the moment in Beta test. See the mail of Basil N7NIX.
If you like to test the new code. Just mail N7NIX. basil (@) pacabunga.com

 

The new code (version 2.5.0) has been running on a few machines for the
last couple of days. I would like to get a few more sites to try out the
new code before it is released.

If you would like to help please contact me directly & I will give you
instructions on how to install the new code. Only the python scripts &
xml files changed to support the latest Winlink Web Services.

Thanks,
/Basil n7nix

Looking for Constibutor / Author

For the website I am looking for people who want to write and post something on the site. They can be configuration examples, an explanation of how you did something. Updates from packet software. And so on. Are there people who feel like it please let me know via the contact form or via e-mail. pd9q (@) packet-radio.net. Thanks.

O Yes, it`s a hobby, so there is no cash 🙂

LinBPQ with Winmor port.

With the help of the config file of Jerry, N9LYA and some help from John, G8BPQ I have setup a Winmor port on my Linbpq.I use a Microham USB II as soundcard device connected to my Windows PC and a direct Cat kabel from my Linux PC to control the TRX.

Here is the section for the Winmor port. (BPQ32.CFG)

WINMOR TNC.ini

Tnx for the help Jerry and John.
