Echo-stink

I've found the 'permit=w1aw,w5yi,etc' line in the echolink.conf only allows for 29 allowed calls. Any more than 30 entries in the list prevents incoming requests on or not on the list access to the node. Short of checking for typo's, using a backslash\ to continue to the next line, or adding another 'permit= line' hasn't proved any results. ???

AllStar Asterisk on a Raspberry Pi
by Steve Zingman 04 Jan '15

04 Jan '15

For the past few weeks we have been playing around with building a cheap simplex node. The idea was a simple RF node for around the house. We started with the NiceRF SA828-U. This was a pretty simple single RF chip based complete UHF radio. At $22 plus shipping, worth a shot. The Sa818 was also considered, but the SA828 was a more complete. <https://www.tindie.com/products/NiceRF/all-in-one-walkie-talkie-module-kit-…> One problem with the single chip radios is that you have no access to discriminator receive audio and to the modulator input, but it's cheap. The nice RF modules do work, but was there a better way? The SA-828 was shipped from China and took forever to get to us in the States. We started looking around for a alternative. Enter the Baofeng BF-888. Available on Amazon, shipped from the US and $15 + tax shipped to Prime account. A number of people have used the 888 for IRLP, EchoLink and AllStar nodes. One thing we wanted to do differently was to take receive audio freon the receiver before the audio anp. A web search will turn up everything you need to know to use this type of radio in a node. Next was the USB interface. The DMK URI or the Repeater Builder USB RIM are both fine pieces of equipment and we highly recommend them. There are lots of CM108 sound FOB mods on the net. We used the WB2EDV carrier board. With all new parts a a sound FOB, total cost about $23 <http://www.repeater-builder.com/projects/fob/syba71-fob.html> Last but not least, the node computer. Doug has created a nice BeagleBone Black node computer. <http://hamviop.org> We really like the BBB board but we wanted to try something else. Since we had quite a few Raspberry Pi between us, why not try it. We know others have said it does not work (well) but was still worth a try. We did not want to create a downloadable image ready to go with scripts to hold your hand. AllStar exported from the SVN, dahdi from asterisk.org and roll your own. The scripts we built will help you install the required libs to compile Asterisk and some simple patches to fix some issues with Wheezy and Raspbian. SSL (res_crypto) and GSM. We also fixed the script that downloads the source for iLBC just to be complete. The test machine for the project was the first rev Pi 256 MB. Keeping the loaded modules to a minimum, leaves about 64MB of free memory. Audio reports are good Surprising since we are do not have access to Discriminator and Modulator. The one complaint we got was the squelch crash at the end of a user transmission. This is a work in process and I would not put it out at a remote site. For a local simplex node, it seems to work. One of the nodes is running full time on the bench at node 2153. I'll post a link to the tar of the scripts and patches. It's worth playing with if you have the time to wait for a compile and want to get your hands dirty with AllStar built from scratch. Oh, and for the heck of it, we call it the PiStar ;) 73, Steve N4IRS and Mike N4IRR. -- "Anything is possible if you don't know what you are talking about." 1st Law of Logic

Re: [App_rpt-users] Possibility of voice control

Skyler, I have done this in asterisk several years ago. Not exactly as you describe. I have played with voice recognition off and on since the late 80's It is a form of "fuzzy logic" The skinny is... It takes some cpu power to continuously monitor the audio and look for a matching pattern. While most folks don't talk with good breaks in their words or even pronounce the words the same way all the time that makes voice recognition not work very well, Example from the news where folks get paid to speak.... The word "IRAQ" as irack but folks say... irock earack earock it leads to a bunch of falsifying commands. The more commands and more varying of types of voice patterns and how they speak, the more false's/errors you will have. While it is possible to generate a error map to re-translate the known errors that will happen with people, it is a very big task not "normally" worth the time. I currently use a single dtmf command to open the interface up. Translate speech to text. Check text against command list. Act on it. IBM has opened a developer interface with "WATSON" but is limited to just a few categories for now like travel. I have interfaced it with other AI servers with some cool stuff but not highly useful, just toys. Still only a toy but I have had hopes to being able to look-up chemical database & msds sheets info for a direct read-back of most important info in the field if needed. I gave up on trying to interface most DB connections on the web, I think I need to have the info on a dvd or local drive. You need to have a translate table for all the known abbreviations that might be used in the DB's. It all takes time to do. To many irons in the fire Perhaps you might like to read on the speech to text systems you can set-up for asterisk for a learning experience. You may get somewhere with that method you can use. Use the text for command. ...mike/kb8jnm > -------- Original Message -------- > Subject: [App_rpt-users] Possibility of voice control > From: Skyler F <electricity440(a)gmail.com> > Date: Sat, January 03, 2015 9:53 am > To: "app_rpt-users(a)ohnosec.org" <app_rpt-users(a)ohnosec.org> > > > Hi, has anybody thought of voice control with AllStar?

Possibility of voice control
by Skyler F 03 Jan '15

Hi, has anybody thought of voice control with AllStar? It might sound kind of pointless, but I think it would draw more attention, and could show that ham radio is high tech and up to date with everything else and 21st century because a lot of phone systems use voice control and I would think there is something for asterisk that would be attachable. Here is an example. A speed dial contact of "Skyler" would be added to 40764 PTT ON "kd0whb connecting link. Allison. Connect to Skyler" (Allison Calls voice control, this makes sure that it doesen't get called at random times) PTT OFF Allison announces "node 40764 connected" I know the voice control technology is increasing every year, and I bet it would even work with a bit of noise. And if not, just revert to the ol' DTMF Resaons •Voice control is becoming a part of everyday life in the 21st century •If someone is mobile, they wouldn't have to punch in the codes unsafely •The DTMF mic broke/ don't have one •Someone forgot the DTMF codes •Just another fun/cool thing that AllStar could support. I am no programmer by any means, and I could never do anything like this. I am just curious about the possibility of someone adding it to AllStar in the future and how hard it would be/ what would be needed. 73 Skyler KDØWHB -- Skyler Fennell amsatnet.info KDØWHB electricity440(a)gmail.com

Mac PTT client
by Skyler F 03 Jan '15

03 Jan '15

Is there any software I can use for mac, where I can talk on my node with a PTT button? If not, is there anything that I can use with wine etc? This is not for other people connecting to my node, just personal use, so iax etc. works as long as there is documentation or instructions on how I can set everything up. 73 Skyler KDØWHB -- Skyler Fennell amsatnet.info KDØWHB electricity440(a)gmail.com
