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. Can you can you get a root shell and use SSH to access? -Doug- On Tue, Apr 25, 2017 at 7:50 PM, Fredric Moses <fred(a)moses.bz> wrote: You seem confused… you still need a linux system running app_rpt with the RTCM’s… think of the RTCM as an ethernet based radio interface vs usb..

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?

Output CTCSS Follow Input?
by Brett Friermood 04 Aug '17

04 Aug '17

I seem to recall discussion of a setting that transmits CTCSS only when local repeater input or linked audio is being transmitted, and does not for ID, courtesy tone, etc. I've looked through the archives but have not found anything. I may just be confusing it with features of some other controllers. The reason I ask is a recent discussion on the other list ended with the answer of being unable to do it since there is not any code in all of asterisk/app_rpt to handle it. Thanks, Brett KQ9N

RSA Public key authentication and Fail2ban?

Upgrading login authentication of the DIAL node for SSH with RSA Public key and disabled passwords. Does Fail2ban work with Public key and is it a necessary option? Thanks, Duane KA1LM

Re: [App_rpt-users] App_rpt-users Digest, Vol 100, Issue 43
by George Csahanin 28 Jun '17

I have had many recent issues with DNS. Verizon at the node I just turned off (28599) was usually good but last week had DNS resolver issues, used google's, and here in Texas AT&T's DNS resolvers are messed up. Slow always but additionally cannot get my iPad to Apples site for cloud service, etc. My iPhone gets there on the cellular network. And I can get my iPad there using celphone as hotspot. But with a GB to move that's not a solution. Bottom line is I like to use google's servers, usually fast. And in rpt.conf I always keep the ip address, not hostnames, of the nodes I usually connect to(27849, 27891) GeorgeC W2DB 2360 -- George Csahanin 10100 Carson Ranch Rd.

receive CTCSS and squelch tail removal
by Steve Wright ZL1BHD 28 Jun '17

28 Jun '17

Greetings, What is the proper way to make sure app_rpt removes the squelch tail from incoming audio? Of course, the calling stations' transmitter must be releasing tone before releasing carrier, but I want to make sure I assemble the controller properly. Thanks, Steve

Reliability / Network Stability
by Benjamin Naber 27 Jun '17

27 Jun '17

Over the course of the last six months or so, I have noticed there have been some issues with allstarlink. Either the allstarlink website doesn't work, connections are radanomly dropped on known high-reliability networks and connected equipment. All without apparent cause. Again today, for no apparent reason, all links on several systems in this area were dropped, and were not able to connect to anyone. Some of our nodes have "direct access" to other nodes specified in the rpt.conf, and those connections worked fine. When a node cannot connect to node 2000, or some other random one, there is an issue. All nodes in this area have different ISPs, so it rules out the possibility of ISP issue. Other folks I have talked to across the country have stated they have noticed similar issues. Has anyone noticed this, and not said anything, or what is going on? ~Benjamin, KB9LFZ

tone sent in usbradio setting
by Pierre Martel 22 Jun '17

22 Jun '17

Hi I am trying to find what is the frequency of the tone sent when we use the command radio tune txvoice?? I am asking cause if it would be 1247 hz we could use the bessel null methode to adjust our tx to 3hz with just a simple rtl-sdr and sdr# the theory behind this is a bit complcated but at a certain frequency and level the carrier is completly or almost completly off. this can easily be seen on a spectrum analyzer. but our sdr# are like spectrum analyzer. so if we would want a 3khz deviation we need to send a 1247 hz signal and adjust the levels till the main carrier disapear on the spectrum analyzer. the maths are this 3000/2.405=1247 you can see the theory at use here: https://www.youtube.com/watch?v=8IBOYoIV5m8 So if there is a way to decide the tone we want we could use that methode to adjust or repeater deviation ( for the voice part at least) now if we wanted to adjust the deviation for the ctcss, this is another story. but could it be calculated by the voice level setting if sent on the same output? thanks for listening to my crazy idea ;-) By the way you can set a radio with a sound card attached to it a known level and use that as the signal to adjust the rxvoice level also. since we can set that with simple audio generating software available free online

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!

Re: [App_rpt-users] DIAL node hack

Good to know about RC1. I had months ago disabled access to root via ssh. Even I have to ssh in as SU with a password. I was wondering if this exploit hack was seen by others, just a heads-up. Duane KA1LM

The node is on a "Guest" server on a University firewalled network. They punch incoming holes to us for only 222 ssh. We have disabled root access and have to SU with user and password to modify files. Duane KA1LM
