[arm-allstar] RPI3 halt button

Chris,

You are most likely experiencing electromagnetic compatibility issues in
your setup. My initial impression is:

1. The original switch wires you were using were resonant at a specific
frequency or frequencies from a nearby radiated emission(s) source. This
source's electric field energy was probably being coupled in to that wire;
hence, causing faults. The wire was acting like an antenna picking up
energy. By shortening the wire(s), the resonant frequency changed and less
energy is being coupled in to that path.

OR

2. Shortening the wires had no effect and by rerouting the wires you got
further away from the source of emi; hence, since the electric field
intensity is lower at the wire's boundary, less energy is being coupled on
to the wire(s). This energy is probably not enough to cause faults.

How long was/were the wire(s)?

OR

3. The long wire, along with the switch, was resonant and acting as a
radiating antenna for conducted emissions signal or signals present at the
gpio pins creating a new non intentional source of radiated emissions
causing emi to something else.

You should do more testing 😁

Regards,
Irvin

Sorry I just reread your message and I missed the fact that this was
Echolink audio. Assuming your primary levels are set correctly as stated in
my last message you should not have to change the echolink levels by that
much. Something is wrong if you do. The default values have worked for me
for years. Do NOT change simpleusb audio levels to change echolink levels.
You first have to setup your primary Allstar levels in the
simpleusb-tune-menu. Then if you want to fudge the echolink levels you can
do this in rpt.conf but you should not have to change these by much. If you
find you do then the problem is at the other end - someones echolink level
TO you and not your issue.

Dave has put out an update to correct a bug that appeared in the last
update regarding simpleusb full duplex. The problem would not have shown up
in  radio connected half duplex nodes but caused a random clicking noise in
true full duplex connections like "radioless" nodes where you were always
listening to the output. After the update the data light (green on the URI)
will show a constant fast rate which is normal.

Also the rx_timeout variable in rpt.conf now has an allowed =0 setting
which disables the timer. This should only be used when absolutely
necessary as it disables the ability to time out nodes that hang. Normally
this timer is set to about 3-4 minutes or 180000 to 240000 which would
limit the amount of time a node could hang before COS was disabled.

Update using the ADMIN menu item 1. Remember that hamvoip updates are
rolling updates. That is if you have not updated in awhile when you do
update you will get this update and all since the last time you updated.

We have deployed another value add to the hamvoip code, the ability to
program the older Motorola radios like the Maxtrac , GM300 etc. on your Pi
allstar server. This makes available the ability for the average person to
program these radios without having to find someone that has an old
computer and the software to do it. It also is a consistent platform so if
it works on one Pi it will work on all. No more hassling with timings, etc.
Complete details are in the link to the howto posted on the hamvoip.org web
page in the howto/software section. Here is the direct link -

https://hamvoip.org/hamradio/motorola_programming/

If you use the hardware suggested and set it up according to the directions
you should be able to program your Motorola radio that previously required
an old DOS computer..

I feel like I'm missing something here. The instructions stop at launching
DOSBox. Isn't DOSBox just an OS emulator? How does the radio actually get
programmed?

Tom,

 The article does not hold your hand so to speak on how to actually program
the radio. The Motorola programs are there and it is up to the user to run
them and program the radio. When dosbox is run the directory with the
software comes up in Norton Commander.

Doug - On my first node I changed wire routing of power supply wires (I'm
using DC/DC down converters to power the RPI3 and BF888 so I can run the
node portable off 12V) and I shortened the wires from the RPI3 GPIO to the
halt button.? Now the halt button works reliably and does not cause start
issues.? So all I can think is I was picking up noise and changing the wire
routing minimized it.? Thanks for the help.

Chris,
?That is a distinct possibility. How long is your wire. It should be short
like shown in the example and mounted at the case. If it were longer you
might need to bypass it with a .1 or .01 uf cap. Also check pin 11. It
should be high - approx. 3V when open. You can also run? 'gpio readall' at
the Linux prompt. This shows the state of all pin. It should be listed as
in and a 1 or hih when the switch is not closed.

Chris,

? I assume you are referring to the howto at the hamvoip.org web page. It
shows where to connect the switch on the Pi 2/3. The script for doing this
is included in the hamvoip release and is turned on by the flag in the
/usr/local/etc/allstar.env file. Here is how to do that.

- Enter the bash shell from the menu selection 9

Edit the file. Type -

nano /usr/local/etc/allstar.env

Scroll down to SHUTDOWN_MONITOR

Change "disabled" to "enabled"

Use Control x? to save the file - answer Y and then return.

reboot the system.

The bit should now work to halt the system. Remember you have to hold the
bit closed for greater than 5 seconds then release for it to work.
