How to Move a Node from one machine to another

2018-05-16T02:25:21Z

KB9LFZ:

if you are not going to use first-time.sh (and it's name derivatives)
or, you are moving your ASL node to an existing Debian or Ubuntu machine;
or, just want to do things some arbitrary way:

Do the following:

Copy the ENTIRE /etc/asterisk folder from the WORKING ASL node machine to:
- another Linux/Windows box for safe keeping,
- (and replace the existing) to your new node host ASL machine

perform side-by-side comparisons to make confirm correct file copy

restart asterisk

plug in the URI

restart asterisk again

check for errors in the Asterisk Console and /var/log/asterisk/messages.
Logs sometimes appear in /etc/asterisk/messages

if:
you get this message: WARNING[23791]: chan_simpleusb.c:2149 setformat: Unable to re-open DSP device 2 (usb28569): No such file or directory
then:
<code> echo snd_pcm_oss >>/etc/modules </code>
and either
<code> modprobe snd_pcm_oss</code>
and check for /dev/dsp or reboot.
<code>ls -la /dev/dsp</code>

Credit belongs to N4IRS for the direct above commands.

if:
/dev/dsp is something like this:
crw-rw---- 1 root audio 14, 3 May 15 18:49 /dev/dsp
then:
<code>chmod 775 /dev/dsp </code>

<code> systemctl status</code>
check to see if any process have failed
usually restarting Asterisk will cause the update node list service to fail.
In this case, you may see something such as:

State: degraded
Jobs: 0 queued
Failed: 1 units

Now do:

<code>
systemctl --failed
</code>
UNIT LOAD ACTIVE SUB DESCRIPTION
● updatenodelist.service loaded failed failed AllStar NodeList updater

Then do this:
<code> systemctl restart updatenodelist.service</code>

if that does not work, then:
<code> service updatenodelist restart</code>

Those who read all the instructions:
- you must make absolutely sure all of the files you copied have the SAME permissions as on the working ASL node.
- you may have to either:
- use sudo if you put ASL Asterisk on a daily use machine that has a normal user, other than root
or, you can just typer <code>sudo su</code> instead of prefixing all commands with <code>sudo</code>

I builds 'em and and I breaks 'em!

Activity Breeds Activity, local repeaters is where new hams go to. If they discover another facet of our hobby and never talk on a repeater ever again, this is a good thing.

Because someone had to be brave enough to mentor the new ham, and give them the knowledge they need to be dangerous, and then a desire to learn more on their own;
the new ham will be the mentor for the next new ham.

KB9LFZ: correct "work IN progrress

'''Work in progress!!!!'''

This project is to enable the use of existing commercial radio such as a Maxtrac, GM300, or GE MVS, among others, to become a programmable radio with an Ardunio.
This means that you will no longer need special programming cables or software to program a radio, whether it be for home, mobile, remote-base, or repeater use.

The reason why I am doing this is to enable free tuning of the radio
without the need to program the radio using normal computer programming
methods, ie, a cable, and a special program that is hard to come by, as
well as must run this program on older hardware

Given that Arduinos can be programmed from just about anything, this
enabled on the fly on at least, on site programming of the radio. I am
working towards enabling the use of these radios, and a couple others
to be controlled by repeater controllers, and allstarlink nodes using
kenwood data command set. Or whatever it is.

Boiled down, this will enable good, inexpensive priced commercial
radios to continue life; anyone who knows how to solder and program an
Arduino can now use a commercial for a repeater VHF/UHF remote base,
Allstarlink, IRLP, Echostink node radio, scanner, whatever.

With the significantly better RX fronts ends on these radios, cleaner
TX, these will significantly outperform any chinese radio attached to
any RoIP node.

The first iteration, the Arduino code will contain the frequency programming. During the maturing of the code, more features will be added such as adding a LCD display to see items such as frequency, shift (if any), PL/DPL (if any), as well as the ability to have a VFO and memory mode. Saving frequencies into memory mode is also in the works.

Sources will eventually be provided as they are found.

As of 20 Jan 2018, the status of this project is Maxtrac and GE MVS radios have been successfully able to tune any frequency within the radio's VCO range, and receiving a signal.

Instructions for connecting radios, repeaters and AllStarLink interfaces including the RTCM, GPS, URI/URI X and like devices.

=Motorola=

==CDM==
CDMs make great nodes. This eBay reseller has very nice cables. Use to connect to URI or RTCM.

[[Media:CDM Cable.pdf|CDM Cable from Kurt Meltzer]] ex-WB9KNX, now KC4NX - Cable 83 has only one output to use for either COS or CTCSS. Use another cable if you need both COS and CTCSS.

==Maxtrac==
The venerable Maxtrac is a radio that was very well built, apparently has very stable reference LO, and can take a beating. When aligned properly, and sufficient *vectored* cooling is made, this radio will last for a very long, time even under several hours with of transmitting per day.

The radio will need to be aligned, and programmed to the frequenc(y/ies) you want to use. You will also need to program the Accessory Option for PL/DPL & CSQ Output.
* Most URIs can accept active high or active low for valid RX signal detection, ie, open squelch. It is HIGHLY recommend in any situation COS is set to USB or active high. This will prevent issues. Too many to mention.
* It is a good idea to program pin 8 on the Maxtrac/GM300 for PL/DPL & CSQ output, active high. This will cause the radio to emit a 5Vdc signal when the squelch is open, and go low when squelch is closed.

===TX/RX audio, COS, and PTT connections===
With the radio facing you in normal operating positing, volume knob on top left, and mic connection right below it, turn the radio over from the right side. The accessory connector is located on the rear, right top of the radio at this point. Starting from left to right, the pins on the top are / and the pins on the bottom are /. If you want to hear audio from the radios speaker, just a header jumper on the far right pins 15 and 16.

This section is a work in progress.

References:
The GM300 section has the link for further reading; the Maxtrac and GM300, are relatively close in design.

==MTR-2000==

==Quantar==

The Quantar can be tricky to interface as it's extremely programmable and you will need a wireline card for I/O connections. By default the I/O will not work unless the "wildcard" table is programed. This wildcard table is Boolean logic of interrupt states in the radio, is extremely flexible and frustrating to debug. It's a base station in it's own class.

The Motorola Syntor X with an Xcat installed makes a great frequency agile remote base. For more information see this [http://wd6awp.net/xcat/ Syntor Xcat] page.

==VRM-850==

==GM300==
These older radios are fairly common and easily to come by due to the narrow banding. Probably the hardest part is finding a computer and the RSS to program them. The Gm300 family has many different configurations, from low band VHF, to 800 Mhz. But the easiest variant of the GM300 is ones with the 16 pin connector.
[http://www.repeater-builder.com/motorola/maxtrac/maxtrac-index.html All about GM300 Radios]

Connections are fairly simple but can be hard to determine which is the correct one to use. This [http://www.repeater-builder.com/motorola/maxtrac/maxtrac-option-plug.html link] is a good place to start.
