Audio Devices not set correctly

kf4dwv <gballance@...>
 

I'm running Cent OS 4.4 or maybe 4.7 from the last information I
looked at.

I was troubleshooting DTMF problems where the IRLP card is not
receiving the DTMF codes but the repeater and everything else seemed
to be working fine. I was trying to connect to a station from the
command line and started receiving the error message "Audio devices
not set correctly".

I found something in the unofficial IRLP manual regarding this and
suggested it was a permission issue with the audio device and audio
mixer. It mentioned running 3 commands from the command line but the
second one –
Chmod 660 /dev/mixer* /dev/dsp* /dev/audio* returned an error message
that the files could not be found.

I was going to try the last suggestion adding it to the bottom of
the /etc/rc.d/rc.local file but could not find that file either.

1. Does this possible solution only relate to RH7 OS or should
it work with Cent OS also?
2. Could this be the problem with DTMF not working in the first
place?
3. If the commands should work with Cent OS, what am I doing
wrong – suggestions? I've used the linux commands to fine a file
anywhere on the system and it didn't find any of them.

That is correct. But I have never seen subtone be a problem before. Do you have power on the board?

The first thing you need to do is install the software. All of the
tools you need to work on the card are in the software, including the
drivers for the card itself. You cannot tell very much without the
node software running.

I found a positive going signal on squelch open. I have the schematic of the 220 version modified. I just added a 2N2222 and a 4.7K collector resistor and reversed the polarity so that I have a 0.7V COS when the squelch opens. I can send it to you direct if you want. It's about 3.5 Meg JPG file. I modified three of those suckers for a COS signal. It is possible.

interface adapter wiring. The only thing I am having problems figuring

For what it's worth the Midland 13-510 owners/service
manual is at www.repeater-builder.com on the Midland
page. Yes, it's a bit fuzzy but it's all we have until
someone sends us a better scan.

The 13-5123 is the 220 version of the radio and the
scans are better on that PDF. I'd be willing to bet that
the audio module is identical so it may pay to print off
the AF unit schematic from the 220 PDF.

Do I need to add a CTSS board to this radio
in order to get COS?
The decode line from a CTCSS board does not give you COS.
If gives you an indication that a tone was decoded. COS is
an indication of the presence of a carrier (i.e. the channel is
busy).

I do have a pin in the mic connector that could be
used for the COS if I nknew where to hook it internaly.
According to my notes pin 1 of the mic jack is mic audio, pin 2 is
mic audio shield, and pin 4 is PTT. IN THE MICROPHONE pin 3
was unused, but in the radio is jumpered to pin 2 (at least in my
radio it was).
Who knows, Midland may have had some mics wired to pin 2, and
some to pin 3? You will have to determine which one is the extra in
your own environment.

Use your VOM and measure the DC swing on the collector of Q202 in
the "AF Unit" module and verify that my old notes are correct and that
is the audio mute control line. On one radio I took a 2N2222 and
paralleled the base and emitter across the same pins on Q202 and the
collector went to the COR output, on another radio I took collector of
Q202 and ran it through a 1K resistor and to the base of a 2N2222
(emitter to ground) and the collector was the COR output.

My notes do not say which one was better, or why I did the alternate
connection. Try both, or try your own ideas and let me know what works.

It is highly unlikely that you will be able to find a matching plug for the
7-pin accessory socket. One came with each radio, but it was unusual
to find them with a used radio.

Several methods were used to get around the missing plug, I saw one
situation where the person took a dead 7-pin tube, broke the glass,
soldered wires to the pins (which was difficult), and then potted the whole
mess.
Another person did the job a bit differently - he drilled a hole in the center
of the 7 pin accessory jack, and ran the cable from a six inch DB9 pigtail
cable through the hole, tied a knot in it for stress relief (I used a
tie-wrap)
and soldered 7 of the 9 wires to the pins of the accessory connector.
in his case he jumpered pin 9 of the DB9 to +12v and used it to feed
power into the radio (it was used as a control receiver).

BTW, the accessory plug wiring for a stock radio is the following:
1 - factory unused, we tied the center conductor of a piece of RG174 to
this pin and the shield to pin 6. The center conductor went to the modulator
input for PL encode (see below).
2 - +12v on transmit (used to power an external PL encoder or DTMF pad)
3 - CM - "center meter" - a DC test point for a zero-center microammeter.
We fed the audio input of the external PL decoder from this pin (shield
went to pin 6).
4 - ground - we used this for the DC ground for the external decoder or encoder
5 - "tone burst" - the audio input for DTMF or tone. It's just the
mic audio line
with a 10K resistor in series with it.
6 - the shield of pin 6 (audio ground)
7 - factory unused, we tied it to +12 to power the external PL decoder

As you can see, pin 1 and pin 7 of the 7-pin connector on the back of the
stock radio are unused as well as the spare pin on the mic jack.

My notes (from the days when this radio was brand new on the market) say
that we used to inject the PL encoder through a 1/4w 100k resistor into the
junction of R361, R361 and C365 on the VCO unit so as not to load down
the modulator circuitry. We used a length of RG174 from the accessory
jack to the VCO unit and the center conductor was connected to the 100K
resistor. Note that the output of the PL encoder has to be cap coupled - the
injection point mentioned above is deep in the VCO circuitry.

Any help would
be appreciated.

Can you run the "speaktime" and "star69" scripts manually and hear them
coming out on the radio? If you can run it successfully from the command

See www.rpm.org/max-rpm/ch-rpm-install.html for some help on installing RPM files. e.g.
rpm -i speaktime-2.0.0-1.i386.rpm
if you have already "downlaoded" it. You could use...
wget http://irlp.kc6hur.net/downloads/speaktime-2.0.0-1.i386.rpm
to grab the file. However, "rpi -i" can also use a URL instead of a file you have already grabbed.

So, should i just copy and paste in the irlp/custom/decode_encode file ????? i have just want to install the star 69 and the speak time script ,that's all.
You would have to install the Star69 script first. You can grab it from http://irlp.kc6hur.net/downloads/star69-2.0.0-1.i386.rpm. Once the Speak Time or Star69 scripts are installed, you can add an entry to your custom_decode file so you can command the scripts to run from DTMF commands sent over the radio.
if [ "$1" = "1" ] ; then "$CUSTOM"/speaktime ; exit 1 ; fi

should i just add this line after the one i have now ???
If it's in /home/irlp/custom that should work.
Mine is a bit different, probably because it's an embedded node. I added the "beep" and the "id_now". The code I use is *24. Looking at your example, it looks like you want to call it with just the single digit "1".
if [ "$USE_SPEAKTIME" = "YES" ] && [ "$1" = "S24" ] ;
then /home/irlp/scripts/beep ;
/home/irlp/features/speaktime/speaktime ;
/home/irlp/features/morse_id/id_now ; exit 1 ; fi
The "exit 0" in your example should be on the very last line of the script.

the nodes are working good at the moment ,no problem too report .
You could always make a backup copy of custom_decode before you modify it!

Short answer: no.

Longer answer: You have a number of issues. The most significant issues are:

1. The IRLP software doesn't bind to a specific interface, so even if you have multiple IP addresses, there's no way to confine each node to a specific IP.

2. The IRLP software normally lives in a specific place in the filesystem. It _may_ be possible to use different environment files to separate them.

3. The IRLP software uses /dev/dsp by default.

However, in some setups (i.e., where you have a block of IP addresses routed to a subnet), it _may_ be possible to use VMware or similar to segregate the two nodes (assuming you have 2 separate parallel ports and soundcards. No guarantees though.

For the record, I'm not a big fan of network newscasters, unless

there's other media better suited to "on demand" news, such as
