<p>Hi Chuck,</p>
<p>Your email is very encouraging. I failed my Tech exam yesterday,
so I am studying more with some online practice exams on eham,com.
I will retest in May. Meanwhile I have setup some of the local
channels on my radio but have not heard any traffic. I think I set
the PL codes correctly.</p>
<p>Regarding digital, I need to learn the apropos frequencies and
the apropos packet specifications (WinLink?). I am reading from
the ARRL Operating Manual, which talks about something like <br/>
</p>
<ul>
<li>APRS</li>
<li>EchoLink</li>
<li>IRLP</li>
<li>Winlink</li>
<li>NRZ</li>
<li>Manchester</li>
<li>Miller<br/>
</li>
</ul>
<p>My intuition is that these are ways to encode binary data on an
audio transmission/reception signal, both digital and analog
signals.<br/>
<br/>
The encoding of data from software structures into bytes occurs
just above these encodings. I have some specified encodings of
common objects I use, using ASN.1 encoding, but more could be
added such as weather SITREPs, stock info and transmission
triangulation data, for instance. After encoding the high level
objects into bytes, then the RFmessage/signal encoding would occur
(from the list above). Currently my ParrotTalk protocol handshake
objects are encoded as well as messages supporting distributed
objects. I use TCP, not UDP, so the idea of a broadcast message is
still a bit foreign to me. <br/>
<br/>
Here is my Java code, I think it still works, but my core
development occurs in Squeak and I am advancing the
implementation, including per-connection config, which will need
up-dating the Java implementation.

</p>
<p>Is there another established mailing list for digital comms over
RF or might we start one so we do not interfere in this list, as
we are off-topic?</p>
<p>I appreciate you.</p>
<p>Best,<br/>
Robert<br/>

<div dir="ltr">Robert,
<div>I for one am interested in what you are working on.</div>
<div>That is where radio is headed like it or not. As long</div>
<div>as we set and use 40 year old analog voice tech we</div>
<div>are going nowhere. On top of that all of the tech</div>
<div>vultures are circling ready to grab up our spectrum,</div>
<div>it is use it or lose it. We lost 3.5Ghz to the cellular</div>
<div>folks, they are trying to grab our piece of 5.8Ghz.</div>
<div>If you are running a digital repeater you well maybe</div>
<div>using one of those bands as part of your link to your</div>
<div>digital repeater. </div>
<div><br/>
</div>
<div>Glad that you got the cable thing straight in order to</div>
<div>use Chirp to do the radio programming and wish</div>
<div>you luck with the digital work, we need to see more</div>
<div>of it in this hobby (as buzzards circle). The zombie </div>
<div>analog repeater count is extremely high everywhere</div>
<div>I travel, I think you could give a safety of life alert</div>
<div>on most of them and no one would hear you. At least</div>
<div>on most of the digital systems I know that I can get</div>
<div>on a talk group and get someone. </div>
<div><br/>
</div>
<div>Keep up the good work.<br/>
</div>

<p>Hey! It worked! I had to seat the cable one last click,
as I saw ttyUSB0 disappear and then appear on unplugging
then plugging in the USB and I also had ftdi_sio module
installed. I seated the cable firmly and read the radio
config. <br/>

<p>Thanks so much and I would say I apologize for all my

</div>
<div>Simply do "ls -l /dev/ttyUSB*" before and after
plugging in the cable. You should then know for sure
which port to use. Otherwise most common cause of no
response from radio is poor connection on the radio
end. Try seating the cable with a little extra push.
In some cases, cables have even needed to be trimmed a
bit to properly seated.</div>

<p>Hi Eric,</p>
<p>Thanks for pointing me this way, although it seems I
am not auto configuring a module for ttyUSB0. I am
attaching the output of <br/>
</p>
<blockquote>
<address>lsmod | sed -n 'p;$=' > lsmod-count.txt<br/>
</address>

<p>Where the last line is a line count. There is no
changes in this output between having the phoe
unplugged versus plugged, so perhaps that is an
indicator that auto-config of a module to talk to the
radio is misfiring. I dunno. Is this where modprobe
comes in? What module name should I install for Chirp
managing traffic over ttyUSB0?</p>

<blockquote type="cite"> Well,
<div>It does depend on the GUI. There is actually a
control panel of sorts if you use Unity or gnome as
your desktop. Under there will be a number of
“applets” for hardware configuration. This was the
gnome project idea of mimicking a windows interface
as well as it’s control panel. However, it is
sometimes not as useful as being able to
troubleshoot and add/remove devices from the CLI.
One should look up lsmod as well as modprobe and
Insmod. If things are working correctly, new devices
will always appear in the /dev directory and may
even have some sort of “magic number” associated
with them. That’s an advanced idea and shouldn’t
really be of concern for this discussion.</div>
<div><br/>
</div>
<div>Now, if you use the “Lsmod” command (not
capitalized, as my stupid autocorrect is trying to
change it) before you plug in the usb cable, you
should see a list of modules and what they do. After
plugging in the cable that connects to your radio,
and doing the same command, you should see 1 or more
new modules loaded. Those modules will be associated
with new devices that show up under /dev. Now, they
may be listed as TTYS0 or TTYS1, etc. those would be
your comm port entries. ttys0 should be associated
with comm 1, etc.</div>
<div><br/>
</div>
<div>Now, if your system is properly configured, then
most of this already happens in background. However,
there may be some cases where you may have to add
your user account to the appropriate group in order
to use the device. There are GUI programs for this
as well as some CLI commands. Now, some of the
commands above may require that you use sudo and log
into root. 2 items of caution here:</div>
<div>1. If you are unsure, don’t use sudo</div>
<div>2. Sudo is dangerous if you mess up. Only for
advanced users! So, be very careful if you do have
to use it.</div>
<div><br/>
</div>
<div>As always, read the associated man pages.</div>
