-------- Original Message -------- Subject: Dtmf pass through From: ki6ies.tasma(a)gmail.com To: app_rpt-users-request(a)ohnosec.org CC: Hello all! I need some help. I am trying to control a cat200 repeater controller via dtmf. It is its own node. I have my other node (uhf repeater)connected to it, from which i would like to send the commands from. I have tried the *4 and the node number. And then i hear "By your command". But dtmf is not making it to the controller. It is making it to the other node, because I can issue it commands. It is just not passing through the other node, which i would like for it to do. Any thoughts? Ian Sent from my Verizon Wireless 4G LTE DROID

Connection troubles and NAT FYI
by Pawlowski, Adam 28 Oct '12

28 Oct '12

While Asterisk works behind NAT just swell, it seems several of the problems I have run into can be traced back to a terrible NAT implementation on our router. We have some rangebooster DLink that NATs even DMZ traffic, and generally breaks inbound anything. portal updates, phone portal, etc, works rarely if at all. Something to keep in mind is to try and remove the router if you have one, and see if it is problematic. I would not leave the system like this, it will be probed via SIP and SSH, but you can quickly eliminate that element from your frustration.

Fwd: Using SVN copy of Asterisk on RaspberryPi (and "usb.h")
by Shane Morris 28 Oct '12

Sorry all, didn't click "Reply to all" - oops! ---------- Forwarded message ---------- From: Shane Morris <edgecomberts(a)gmail.com> Date: Sat, Oct 27, 2012 at 11:59 PM Subject: Re: [App_rpt-users] Using SVN copy of Asterisk on RaspberryPi (and "usb.h") To: "Ramesh Dhami (VA3UV)" <Ramesh(a)va3uv.com> Hey Ramesh, I agree, no one seems to really care about the RPi at the moment - theres glory in open sourcing those video drivers I alluded to before, and getting Plan9 to work on it, and believe you me, I'd love to see that, but the thing is, right now, the blokes on the ground who don't have the software to do what they need are suffering. The other thing is, RPi forums are not coming to the party. Unsure as to why. I have noted that I'm using an older version of Asterisk and thats a deliberate thing - newer versions of Asterisk don't have support for app_rpt, as far as I'm aware. Possibly they see we're using such an old version, and wash their hands of us straight away due to compatibility issues...? I had a similar situation with FreeSWiTCH once, downloaded the trunk the night before they did a big update from 0.4 to 0.5 and of course, they'd changed the way the config files worked, totally. Went onto IRC to talk about it, they were really good about it, but they kind of said, "Gee, you must have downloaded the trunk at the wrong time..." Of course, I refuse to let my URI become an AU$180 paperweight. Practicality: there is no aptitude package for the kernel source. Its as simple as that. From 3.1.9 to 3.2.27+, not a cracker. They cite this is a fast moving target, and while I sympathise with them, this thing *is* moving, it leaves poor blokes like you and I out in the cold. And I bet we're not the only ones asking about the kernel source...! I've tried using "apt-cache search kernel-devel" and nothing. I'm considering adding mainline Debian repos to aptitude, and downloading the kernel source for Wheezy from there. I may have to then disable the mainline repos, I'd actually run into issues with the compilation of Asterisk (before realising app_rpt wasn't able to be selected) and the particular architecture - GSM codec won't compile for an ARMv6 target, must be generic ARM. That should, in theory, work. Since the package is source, and not a platform specific application, theres no case of it downloading an x86 package, say, and trying to execute it. As for the hooks? Unsure, there would be a particular directory structure that it would create. But then theres a proviso: since its a "canned" package, will it actually work? I've actually installed tonezone2-dev from aptitude, and then was told, don't, it won't work. I must install the source version of tonezone included with Zaptel included with the SVN version of Allstar. I don't doubt why. They built it. Plus is the tonezone2 too new? Etc etc. I didn't really ask why, I think understand enough.To get myself into trouble, evidently. I cant sleep at the moment, and I'm not tired. Might grab a coffee, drag out the Macbook out to the dining room where my DJ rack with the equipment in it sits in the corner, and try this adding repo thing. I encourage you to try the same - if only so we can compare notes. I take it you're in Canada with a "VA" callsign? I was VK2FPGA before I let it lapse due to personal issues. I'm doing this for a community group at the moment who, at a particular part of the year, get a two week temporary licence, and use Simoco SRM9000s on UHF. If I can get this working, I might be able to give my mate this as part of his wedding present, although I'm sure his bride will question the applicability to her ^.^ Don't worry, they're getting a lovely photo frame that I'm going to encourage them to put a photo of their special day into. In any case, Ramesh, I hope this is a little food for thought for ya, I'm trying to think about ways around the problem. I mean, there has to be some way around it, its Linux for crying out loud! It *is* the hackers OS, after all... Hope this helps...! Shane.

Cant connect or Stay Connected UPdate
by Jim W7RY 27 Oct '12

27 Oct '12

Well I think I figured out why my node 28238 can connect. It registers just fine, but it’s not on the status page. BUT. I added this line into my rpt.conf file: 2560 = radio@208.70.77.197:4569/2560,NONE And now it will reliability connect to the WIN system. I also installed an ISP supplied router in place of my D-Link router. That also seems to help. So why doesn't it show up on the status page? And when I look at connected nodes on 2560, my node is listed but no information is displayed? Thanks 73 Jim W7RY

Talk-through tone....
by Ramesh Dhami (VA3UV) 27 Oct '12

27 Oct '12

Hi Guys; I have just updated to app_rpt v0.307 from 0.306. My main motivator was to get rid of the darn squelch crash on my 220 repeater! So, I have added the following 2 COP commands to rpt.conf 882=cop,58 ; talk through tone 883=cop,59 ; normal ctcss So the cop,58 command works great for LOCAL RF users - no more squelch crashes - YEH :) However, we are not hearing remote activity (from connected links) or any 'commanded' telemetry (link status, etc.) - it's all there, but no PL is being transmitted. What am I missing??? Here is my usbradio.conf file contents: hdwtype=0 ; Leave this set to 0 for USB sound fobs modified using ; the instructions from usbfob.pdf. Use a setting of ; 1 is for Dingotel/Sph interfaces. eeprom=0 rxboost=0 ; 0 = 20db attenuator inserted, 1= 20db attenuator removed ; Set to 1 for additonal gain if using a low-level receiver output rxctcssrelax=1 ; reduce talkoff from radios w/o CTCSS Tx HPF ; Do not change this, leave this as a 1 txctcssdefault=103.5 ; default tx ctcss freq, any frequency permitted rxctcssfreqs=103.5 ; rx ctcss freqs in floating point. must be in table txctcssfreqs=103.5 ; tx ctcss freqs, any frequency permitted ;rxctcssoverride=0 ; Set to 1 or yes to start out in carrier squelch mode carrierfrom=dsp ; no,usb,usbinvert,dsp,vox ; no - no carrier detection at all ; usb - from the COR line on the modified USB sound fob ; usbinvert - from the inverted COR line on the modified USB sound fob ; dsp - from RX noise using dsp techniques ; vox - voice activated from RX audio ctcssfrom=dsp ; no,usb,dsp ; no - CTCSS decoding, system will be carrier squelch ; usb - CTCSS decoding using input from USB FOB ; (currently not supported) ; dsp - CTCSS decoding using RX audio in DSP. ; rxdemod option must be set to flat for this to work. rxdemod=flat ; input type from radio: no,speaker,flat ; no - RX audio input not used ; flat - Use RX audio from discriminator (before de-emphasis) ; speaker - use de-emphasized audio txprelim=no ; Audio processing on left output channel: no,yes ; no - Audio is not pre-emphasized and limited. ; Suitable for use on a microphone input ; yes - Audio is pre-emphasized and limited. ; Suitable for direct connection to an FM modulator txlimonly=yes ; Audio limiting with no pre-emphasis on output channel: no,yes ; no - Audio is not limited. ; yes - Audio is limited. ; Suitable for transmitters with no limiting but with pre-emphasis. txtoctype=notone ; Transmit tone control type: no,phase,notone ; no - CTCSS tone encoding with no hang time ; phase - encode CTCSS and reverse phase ; AKA ("reverse burst") before unkeying TX ; notone - encode CTCSS and stop sending tone before unkeying TX ; AKA ("chicken burst") txmixa=voice ; Left channel output: no,voice,tone,composite,auxvoice ; no - Do not output anything ; voice - output voice only ; tone - CTCSS tone only ; composite - voice and tone ; auxvoice - auxiliary voice output at headphone level for monitoring txmixb=tone ; Right channel output: no,voice,tone,composite, auxvoice ; See txmixa above. invertptt=0 ; Invert PTT 0 = ground to transmit, 1 = open to transmit ; This is the collector lead of the 2n4401 on the modified ; usb sound fob. ; please refer to the howto for the procedure to do this. duplex=1 ; Full Duplex ;rxondelay=20 ; Uncomment and/or adjust for simplex nodes to eliminate "Ping Ponging" ; or "Relay Racing". ; A positive value here will instruct the usbradio driver to ignore the ; COR line for a specified number of 20mSec intervals following the ; release of PTT.

CT weirdness
by Matt Beasant 27 Oct '12

27 Oct '12

Hi I am having a lot of strange things happen with my CTs on my node. I have 3 nodes defined on this computer. Each has an entry in rpt.conf but regardless of what I put in the telemetry stanza I cannot change the CTs! I have renamed the telemetry sections in the node definition section of the rpt.conf file with suitable names and used the same name in the title of the telemetry section i.e. "telemetry=telemetryNODE1". Each node has its own name for the telemetry section. I have no idea where the CTs are being defined at this point as any changes that I make, do not make any difference to the tones heard on the node. There are some really cool CTs I am hearing right now on these nodes but I have no idea where they are being defined from! Has anyone had this before or could help me determine where I am going wrong please? Thanks, Matt G4RKY

Using SVN copy of Asterisk on RaspberryPi (and "usb.h")
by Shane Morris 27 Oct '12

27 Oct '12

Hello all, I am using Raspbian on the RaspberryPi, which is a "wheezy" image, upgraded to the latest kernels, using an aptitude copy of dahdi. I SVN checked out 1.4.23-pre of Asterisk as per the link on the Drupal site, and have been mulling over the various issues as they popped up during compilation. Where I've hit a brick wall is the "usb.h" file needed by chan_simpleusb.c. I've had a poke around the guts of my Raspbian install and tried a few files from the headers src package, but nothing seems to work. I've also installed libusb2-dev from aptitude, again, to no avail in terms of placing a "usb.h" file into the /usr/local/include/ folder. So, my question is this: while I can find plenty of references to "usb.h" in the source files on the various repos on the net, I'm unable to find a copy of the actual "usb.h" file - if someone could shed some light on where I could potentially wget this file from straight into my include folder, that would be great. As for my application, I'm using a RaspberryPi for the fact its very low powered, and since I'll be using a 10Ahr Lithium solar/ performance car battery (started off as solar cells, were adapted to performance cars like the Subaru WRX) and a solar panel/ controller, I can gain autonomy over a weekend operating period. In short, I don't want to drag a generator to the remote base to top off the batteries if I can help it. The URI will be hooked to the Pi on one end, and a Simoco SRM9005 on the other end, through a set of custom cables I'm (slowly) soldering up. I did some more work on them today in terms of the DB25 to URIx cable (which will go to a 5 pin DIN socket, then 5 pin DIN plug to DB15 on the Simoco). On the client end I'll be using IAXRpt on my Macbook Air, which has OSX 10.7 and the latest, sound enabled, WiNE package, along with Winebottler wrapper program to make it nice and GUI like for me - not that I'm afraid of a command line, I just like some things to be simple, and sometimes our PEKAC troubleshooting has to be done with non-experienced personnel, who would faint at the sight of a CLI. I've also got a Linksys SPA942 I want to try in terms of VOX activation, but thats a secondary concern now I've got IAXRpt working successfully on my Mac. Of course, success (under test conditions) will be I press "Ctrl" on the Mac, and I hear my voice come out the SRM9025 head, and vice versa, PTT the SRM9025 head and hear it come out the laptop. This will be interesting, as the MBA doesn't have a microphone port, only a built-in mic, and the Bluetooth stereo input device I bought at Aldi didn't work... I also want a DJs "stick" headphone, as my role in these weekend expeditions is PEKAC and general support, as well as some operation - apparently I have a good, strong radio voice. Ok, enough rambling, as you can see, I'm using the various properties of the systems to gain advantage over say a vanilla Limey Linux install on an Atom. Plus I like ARM. I like a challenge, and if I were to get this working, I'm sure my friend Andrew will be able to use my Raspbian image on his Pis to make further remote bases for next years expedition at Marramarra National Park. He has more Pis and Simocos than me... Thanks in advance for any help you guys can give - I'll be interested to hear your responses.
