Re: Initiate a Remote Call via SSH??

Yes, you can do anything remotely that is possible on a local console. I have not had a console attached to my nodes in years, in fact on my mobile node it is not even possible for to connect a keyboard and monitor, and I never use the web tools. SSH is much faster and more convenient, especially from my cell phone. No passwords are required with SSH (although that takes some additional extra effort generate and use SSH keys once).

decode 9200
decode 73

and whatever other commands you might want to use.

i have no idea how too "install a script",, i never did it except like

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!

Yep. See http://garymcduffie.com/irlp/3055/aumix (upper screenshot)

Note, the settings shown in the picture were eventually changed due to
bass distortion showing up on the scope. That whole setup is gone now.
It was a part of a computer that got hit by lightning last year. Also
note that the Line level being turned all the way down (lower

Re: Tweak frequency response

Marshall Oldham
 

-Hi Dave, it acutally may be de-emphasized audio.
Yes it should be de-emphasized audio.

It is available at
the 9pin connector on the back of the Alinco radios. Using Marshall's
cable and I believe everyone is using this arrangement with Alinco's
as node radios. Sounds okay coming out of node, but by the time it
goes through another node and then the link receiver at the repeater,
just not bright enough for my tastes.
That is because the originating audio is pre-emphasized by the users radio.
Then de-emphasized on the node radio receiver and sent through the internet.
Then pre-emphasized on the other end of the IRLP connection transmitter,
then de-emphasized by the link receiver at the repeater,
then pre-emphasized again on the repeater transmitter.

Every time that the audio gets de-emphasized / pre-emphasized in this audio connection chain,
it gets slightly tweaked. Unless the de-emphasis and pre-emphasis curves were prefect. Which is probably not the case.

By what you have described about your audio path, the de-emphasis and pre-emphasis is happening 3 times to the audio finally coming
out your repeater.

Usually this problem is caused the Pre/De emphasis being wrong on transmitter side. Running IRLP audio into a transmitter with no PRE- emphasis. This should be noticeable on all nodes that connect there. The RECEIVE side being wrong, usually causes the audio to be very tinny.

And before you ask, you can draw de-emphasized audio from the volume pot
(usually one of the end pins, not always) and then gate it down (variable
resistor, 10 turn makes it easier to fine tune) to produce a nice low-medium
level for the sound card. If you give the card full volume, distortion will
be the result (overdriving the sound card). If you underdrive the sound
card, you'll get added noise (hiss). You'll need to figure out how much
drive, then adjust the sound card as needed (software adjusted volume AND
the input level resistor).

That is the problem... Don't use discriminator audio. Audio should be
de-emphasized before sending it in to the node.

Re: Tweak frequency response

Rick Bates <HappyMoosePhoto@...>
 

Is it possible that you're getting audio from the wrong point in your radio
(i.e. using de-emphasis)?

Ideally it is best to have flat audio, what comes in, goes out exactly the
same and let each user/repeater do the same. That way if a particular
station sounds crappy, it's their issue not the system between the ends (and
far easier to track the problem).

And for an OF like me, my ears have a rapid fall off above 3 KHz (nerve
damage, constant tinnitus), so boosting highs would help me. I mention this
because some prefer audio rich in lows too so having flat audio negates
personal issues with audio as well.

Any audio manipulation should be done on the user end (the user radio), not
the system to relay that audio.

Having had one, I don't think it will do what you need. It will
"massage" the bandpass, but can also lead to distortions that I didn't
like seeing on the scope. You're better off letting or making the
interface correct the response. Try different pick off points,
different input coupling, etc., to get the response flatter. You can
also rc/lc-shape the response, but I'm one of the poorest at doing that.
From what you say, you are probably a bit on the bassy side. I know for
an OF like me with bad ears, that makes for really poor copy. Those
highs are needed for good intelligibility.
