Re: [App_rpt-users] Micro-Node RTCM

The RTCM uses a 16 bit DSP with a tightly integrated interrupt driven firmware package written in c http://www.microchip.com/wwwproducts/en/dsPIC33FJ128GP804 If you're interested here is a link to the open-source software for the RTCM.. http://svn.ohnosec.org/viewvc/projects/allstar/voter/board-firmware/?root=s… From: App_rpt-users [mailto:app_rpt-users-bounces@lists.allstarlink.org] On Behalf Of Doug Kingston Sent: Tuesday, April 25, 2017 9:41 PM To: Users of Asterisk app_rpt Subject: Re: [App_rpt-users] Micro-Node RTCM I know that I would have a GPS with 1pps feed to get the timing. Once you have that, what is different in an RTCM other than nice packaging? What is the core processor technology inside the RTCM. I am assuming is some form of ARM processor.

The alternative would be to roll my own with a Raspberry Pi 3 and probably the HamVOIP.org distribution. Who out there is using the RTCM? I can find very little information beyond the manual and I am concerned that the software may not be maintained and that there is not enough access to the underlying Linux system. > > Who can tell me more about the RTCM? > > Has anyone rolled their own with a Pi3?

TK-820 Config Question
by Scott Westerman 21 Jun '17

21 Jun '17

My setup is a Raspberry Pi 3, URIx (no eprom) and a Kenwood TK-820. I'm getting good audio out when I use iaxrpt, the IDs and times transmit fine, but inbound rf signals to the repeater can't be heard and don't trigger beeps, etc. When manually open the COS, I can hear the squelch noise and the inbound audio. Here are my settings. Any advice on what I might be doing wrong? Card is: 0 Name is: usb Rx Level: 500 Rx no-delay: 0 Rx audio-delay: 0 Tx A Level: 500 Tx B Level: 500 preemphasis: no deemphasis: no plfilter: yes rxboost: yes PTT: Active LOW PTT status: Un-Keyed CTCSS (input): CM108/CM119 Active LOW COS (input): CM108/CM119 Active HIGH COS (test): Un-Keyed COS (composite): Un-Keyed Thanks very much for any wisdom you can share!

What is the "debian" user in the DIAL distro?
by Steve Passmore 08 Jun '17

08 Jun '17

Does anyone know what the user "debian" is used for in the DIAL distro? I had a node compromised where it appears they guessed the password for the user debian. I note on other un-compromised nodes there is a preexisting user "debian" with a password set. The attacker installed a bitcoin miner, storing their files under /var/tmp/.new chrootkit reported it as possibly being the Mumblehard backdoor. I'd suggest anyone with a DIAL node, at the very least, remove the user "debian"'s password. passwd -d debian Steve, k6kya

RTCM Simulcast and 9.6 MHz Phase locking
by Joe Moskalski 07 Jun '17

07 Jun '17

I wanted to throw this email out to the group for all those who want to simulcast with the RTCM. For those who don't know, in order to make the RTCM suitable for simulcast you must have a more accurate 9.6 MHz clock for the RTCM in order to ensure the audio sounds acceptable in the overlap areas. I did this a few months ago using 9.6 MHz OCXO's. This worked reasonably well. Not as well as I would have liked but the system was very usable, but of course I wanted it to be better. Since the PCGM (Programmable Clock Generation Module) is no longer available, I decided to roll my own as some say. I created a PLL circuit that can accept a 10 MHz, 1 MHz or 100 KHz reference input and produce a phase locked 9.6 MHz out for the RTCM. I have been testing this over the past few days and it has made an great improvement in the audio quality in the overlap. The quality of the audio in the overlap areas sounds very, very good, it's very similar to what I expect to hear in commercial simulcast systems. My circuit is heavily based off of an old Motorola MSF5000 HSO PLL circuit that I was able to adapt and modify to my needs. There are other uses for this circuit that make it attractive for simulcasting but I wont get into them here. I am will to share my schematic and bill of materials (digikey) with anyone. Please send me an email and I will be willing to share all of my information on the project. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

Re: [App_rpt-users] What is the "debian" user in the DIAL distro?
by Thor Wiegman 05 Jun '17

You're not the first person I'm aware of to have this type of problem. AllStarLink nodes are an easy target to become bitcoin miners and members of botnets. Most people installing these nodes don't know the basics of Linux system administration and the defaults aren't even remotely secure. Not only should that "debian" user be deleted, the appropriate changes to SSH need to be made to prevent the superuser "root" from logging in remotely. That is one of the first things that everyone needs to be change after installation of a DIAL system, not sure why it's even allowed by default. I've noticed that a lot of node ops tend to login as root and execute commands as the root user. Crazy! It's an extremely dangerous and insecure thing to do, but people new to Linux don't know any better. It would be nice if the default installation were setup in such a way that prevented or discouraged login by the superuser. It's odd that sudo doesn't appear to be installed by default. Would be very nice if the installation script prompted for the creation of a user account with proper permissions in much the same way as standard distros do. Not perfect, but it's a start. Most of these systems are being run by people who are new to Linux. They don't know about Linux/Unix system administration and nobody is "elmering" them in it. The result is people taking dangerous shortcuts and developing bad habits. The community would benefit from some guidance in system administration as well as from some improved defaults in the distro.

No Receive Audio Since Dial Swithover
by K7ILO 30 May '17

30 May '17

Hey Gang. First, I have no idea of where to start looking so this is why I'm asking this. Second, I know this has probably been solved through the group here so forgive me since I hadn’t checked this email in some time. I was recently upgraded to the DIAL distro of allstar and I am using the same usbradio.conf file I used under ACID. Now, I do not have any receive (inbound) audio but I do have transmit (outbound) audio. Is there some new mixer settings that has been added to DIAL or new parameters I need to configure? Thanks all for any assistance. Harold K7ILO

Re: [App_rpt-users] New router problem?

Sorry strike what I said in the last email. If the raspberry pi is setup for dhcp then the pi would only get one IP address. So look at the pi ifconfig see if it does has two addresses.

New router problem?
by Te Bussell 28 May '17

28 May '17

I bought a new Netgear router because the older one had problems. The new Netgear R6220 assigns an IP address to my wired R Pi node, but I also assigned a static IP. Both of these internal IP addresses are "pingable". I want delete the DHCP assigned address. I think this is causing a problem. Any suggestions? Cheers - 73 Bill KB9WKR Sent from my iPad

Temporary stop, then restart asterisk
by Bob Pyke 28 May '17

I have a need to temporarily disable the repeater, then enable it. Timing is critical, so a delay is undesirable. What is the best way to accomplish this? I will be logged into the node. Thanks, Bob Sent from my iPhone

DIAL firsttime questions
by Bob 27 May '17

27 May '17

I'm not familiar with "Domain Name" and FQDN when running firsttime. Is the DN the IP address of my router, and the FQDN the RPi IP address? Thanks, Bob
