a silly question perhaps,
but if the mic needs to be attached to a 'hangup plate' is said plate earthed to radio chassis?

I would like to know exactly what connections you are using on the radio and on the IRLP board and what is connected to what. It shouldn't be complicated.

Keep in mind it doesn't matter what is connected to pin 8 if there isn't a shorting plug in the microphone connector.

Re: New install

Hi William,
Is this a 8 channel 16 channel Motorola ? If it is a 16 channel you need to program
pin 8 on the Motorola to  Select PL/DPL & CSQ Detect and active low
You also need to make sure your active low on the IRLP board
and I always use a 10k resistor on the pink side of the sound fob.

Good Luck !!

Would the audio be a separate issue? Could this be a software issue should I try reinstalling?

Re: Resetting the root password on a PiRLP node (or any Pi-based Debian node)

I'll second the versatility of Notepad++ Dave.
I've used it to paste the content of an email header, save it as *.txt, and the syntax will be true when re-opened with MS notepad.
It's also handy for removing all the >> etc from the email body, and for finding/correcting bad spelling like color {^_-}

I finally got it to work. The problem is that if you use "Notepad" under Windows it will add a carriage return without you knowing, and put the required changes on a separate line, which is subsequently ignored by the Pi. That was the case with my setup when I tried. You can try Wordpad instead, or better yet use Notepad++.
Do yourself a favor and download Notepad++. It is a better editor. To edit the config.txt file you will need to use it anyhow.
https://notepad-plus-plus.org/downloads/
At the end of the line in cmdline.txt, add
rw  init=/bin/bash
(note this is different than before, using bash instead of sh)
This will make your cmdline.txt file read as follows, or similar (BUT ALL IN ONE LINE - very important)
dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=PARTUUID=c4372d80-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait rw init=/bin/bash
Under File, choose Save.
There was one other change I had to do as the monitor would not accept the resolution that defaulted. In the config.txt file, there is a line that says:
#hdmi_safe=1
Just remove the "#" from that line so it looks like
hdmi_safe=1
When complete, under File, choose Save.
Then properly "Eject" the SD card from the system, or sometimes the changes are not saved. Put the SD Card back in the Pi.
Also, you have to make sure the HDMI cable is plugged into the port closest to the power input.
Now when you power it up, after seeing a bunch of log info on the screen, press enter and you will get a prompt that looks like:
root@(none):/#
At that prompt, use the command
passwd  root
You may see a prompt come up saying "random: crng init done" in the middle of changing the password, as the random number generator uses keystrokes to set the randomness. Just ignore and keep typing. You have to enter the password the same twice. Also, PLEASE check the number lock and CAPS LOCK on the keyboard, as I imagine these are responsible for a number of password problems.
When it says you are successful in changing the password, type the command:
sync
Then press CTRL-ALT-DEL to reset the pi. Once it shuts off (before it fully reboots), remove the power plug, and pull out the SD card again and put it back in the computer you used to edit the files, and return the two files to their original (cmdline.txt and config.txt)
Now, when you boot the pi, you can log in as root with the new password you set.

I ohm tested the GPIO cable looks good It follows the picture on the irlp website. I have pin 11 on gm300 attached to pin 8 on irlp cable i also ohm tested the cable as well from radio to board. I have played with the mixer moved the sliders all the way up tested no audio as well as in the middle no audio. It does work correctly on audio out I can turn it up and down and it changes the transmit audio.

New Years Eve Around the World QSO Party

k9dc
 

The fourteenth annual New Years Eve Around the World QSO Party on Reflector 9600 gets under way officially at 10:30 UTC (05:30 US eastern) Tuesday, December 31. It continues (officially) until 10:30 UTC Wednesday January 1. I say “Officially” because you are welcome to connect much earlier than that (now if you want) and stay as long as you like.

Please note: Reflector 9600 is a different location than we have used in past years. 9600 is a relatively new reflector co-located with server4 in Sydney, and has not had a lot of use. It is the same machine used primarily to serve up IRLP VPN clients in Australia, Asia and Africa (for more information on the IRLP VPN service, see https://irlp.groups.io/g/IRLP/files/IRLP%20VPN%20Service).

This is a casual informal party with no net control or designated operators anytime during the event. Simply stop in, greet your friends, make new ones and simply enjoy yourself as the New Year wends its way around the planet, beginning in New Zealand 11:00 UTC (Dec-31) and ending in Hawaii at 10:00 UTC (Jan-1).

This is an IRLP only event. Please resist the temptation to bridge folks in from other networks just because it sounds like fun. Instead, invite your local friends over to your repeater or encourage them to use a local resource to join in.

Auld lang syne!

Possible that you have a broken wire on the GPIO.

Your audio problem is likely mixer related. alsamixer is the program you use to set the levels. I assume you are using a USB based sound card, so the sliders shown should be pretty obvious.

The audiotest command does work correctly keys radio and is adjustable with alsamixer. I am using a motorola radio gm300 . I have tried another radio and confirmed i have audio out squelched and de-emphasized.

Thank you
Billy

What DTMF codes are you seeing when you press the buttons? A table like this would help:

Pressed : Seen
1:1
2:0
3:1
4:4
5:4
6:5
7:5
8:8

Possible that you have a broken wire on the GPIO.

Your audio problem is likely mixer related. alsamixer is the program you use to set the levels. I assume you are using a USB based sound card, so the sliders shown should be pretty obvious.

Resetting the root password on a PiRLP node (or any Pi-based Debian node)

I finally got it to work. The problem is that if you use "Notepad" under Windows it will add a carriage return without you knowing, and put the required changes on a separate line, which is subsequently ignored by the Pi. That was the case with my setup when I tried. You can try Wordpad instead, or better yet use Notepad++.

Do yourself a favor and download Notepad++. It is a better editor. To edit the config.txt file you will need to use it anyhow.
https://notepad-plus-plus.org/downloads/

At the end of the line in cmdline.txt, add

rw  init=/bin/bash
(note this is different than before, using bash instead of sh)

This will make your cmdline.txt file read as follows, or similar (BUT ALL IN ONE LINE - very important)
dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=PARTUUID=c4372d80-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait rw init=/bin/bash

Under File, choose Save.

There was one other change I had to do as the monitor would not accept the resolution that defaulted. In the config.txt file, there is a line that says:

#hdmi_safe=1

Just remove the "#" from that line so it looks like

hdmi_safe=1

When complete, under File, choose Save.

Then properly "Eject" the SD card from the system, or sometimes the changes are not saved. Put the SD Card back in the Pi.

Also, you have to make sure the HDMI cable is plugged into the port closest to the power input.

Now when you power it up, after seeing a bunch of log info on the screen, press enter and you will get a prompt that looks like:

root@(none):/#

At that prompt, use the command

passwd  root

You may see a prompt come up saying "random: crng init done" in the middle of changing the password, as the random number generator uses keystrokes to set the randomness. Just ignore and keep typing. You have to enter the password the same twice. Also, PLEASE check the number lock and CAPS LOCK on the keyboard, as I imagine these are responsible for a number of password problems.

When it says you are successful in changing the password, type the command:

sync

Then press CTRL-ALT-DEL to reset the pi. Once it shuts off (before it fully reboots), remove the power plug, and pull out the SD card again and put it back in the computer you used to edit the files, and return the two files to their original (cmdline.txt and config.txt)

Now, when you boot the pi, you can log in as root with the new password you set.

I acquired that as well with the irlp board could that also cause no audio?
