The Asterisk Amateur Radio Network will be join with the Drake State Technical College Amateur Radio Club promoting the use of amateur radio along with giving thanks and appreciation to our men and women who have served and who are serving now in the Arm Forces. This will be a great day for all to come out and support the troops on a job that continues to be at the fore front of our mission for the country and the world.

We hope to have HF/VHF/UHF radio system setup for operations. Making contact to other ARMAD or any amateur radio stations. We will also use VoIP systems such as Asterisk, IRLP and Echolink for those who would like to call in. There is also a special IRLP reflector for all IRLP station to call into. This IRLP reflector is experimental node 0011. This is a special IRLP reflector and you will need to make sure your IRLP node are setup to make the call into. More information will be put out on these special parameters in a few days. So stay tune.

For Asterisk call in, one can call in on AST node 2048, this way you will be able to talk to IRLP and echolink nodes alike. For Echolink nodes one can call in on the Kansas Reflector, node 44445 and W4WWM-L, node 54572. Any of these connections will be fine. We would also like to try something new. We will have a control Ham Radio operator standing by for third party calls. This way we can also show the power of Asterisk PBX. So look for more special information on how this will happen here on this site.

Anyway we will look for all to come out and support this great day for ARMAD and to make radio contacts using our hobby, amateur radio to communicate. 73 and Stay tune for more info!

The meeting place is the same as before, which is 6380 Pulaski Pike, NW, Huntsville, AL.

The directions: At the intersection of Pulaski Pike and University Drive, turn on Pulaski Pike to go north about 8-10 miles. With in the 8-10 miles you will pass the intersection Pulaski Pike and Wind Chester, continue on Pulaski Pike for one more mile look to your right, you will see two Churches, look for the Church that slightly set on o hill and a red brick building, which would be the second church on the right.

Turn at the red brick mail box and come around to the GYM. This will be the meeting place. I’ll set up a talk in on Harlie’s (KB4CRG) 444.575 +offset, PL 100hz

We will have the Bamawisp (A Wireless Internet Service Provider) site team there to give us the total run down on what it’s going to cost us to run the site as a group, they will also give us access information for Cap Shaw Mountain and we will be talking about the test Repeater/remote system that will be going on the hill top. I’ll also entertain those who are interested in building there on Full Duplex or Simplex AllStar nodes.

At this web site you can see the growth of the All Star System ( http://allstarlink.org/). So please come out to support the historic meeting. We need the monetary support as a group for the site location and to place the test system on the air. It will be one of the first Asterisk Amateur Radio Network system in the area and looking to build the network through the state and beyond. We have some technical support from Atlanta, GA and San Diego/Los Angles, CA. Also web site support with lots of information from Derby KS. We just need to come together as a group and make it all work.

Oh, if you can’t make it to the meeting, please send an e-mail to let me know you would like to be a supported and I will put you on the list for the ground breaking system crew, which will be place on the web site (http://asteriskradio.net/). Scroll down until you see the Asterisk Amateur Radio Network (AARN ) and you will see information from the last meeting as well as up to date. If the link broke for some reason let the website administrator know. The proposed system information from the first meeting is available at http://searn.alertradio.net/blog/aarn-mhal/

Like to make a trip up to the site the following weekend to collect information for the plotted coverage of the site using a program call Radio Mobile. Would need some one with a GPS to take site information. Thanks and hope to see you all there Monday.

URI – USB Radio Interface

• Connect two-way radio to PC
• Fast and easy!
• $$ Very low cost $$
• USB Interface – no need to open PC case
• Open source: asterisk, app_rpt
• Connect to radio’s interface connector
• Optional configuration EEPROM
• High-quality full-duplex audio
• Optional high level op-amp
• 3 User I/Os

More information is available at:

Yes! The USB FROG/OB is still around too.

From the qrvc.com web site the following features are mentioned:

chan_usb radio contains all of the interface code to interface app_rpt to a CM108 based USB sound fob.
In addition it contains DSP code to do CTCSS encoding and decoding, squelch, pre-emphasis and soft
limiting, de-emphasis, and audio level adjustments.

Basically, you only need to make 3 or 4 connections to your radio:

• Discriminator audio, de-emphasized audio, or speaker audio.
• Transmit audio (direct to modulator, or microphone)
• PTT

A new doorway is quickly opening to continue the progression of Asterisk as the way to interconnectivity.

FXS — Foreign Exchange Station

FXO — Foreign Exchange Office

An FXS device initiates and sends ringing voltage. FXS sends the voltage to an FXO device, which receives it.

The phone receiving the call is the last FXO device in the chain, and when it receives voltage from an FXS device, the phone will ring.

Connect the outside line to an FXO port on your Asterisk server to receive voltage from the outside lines.

Connect the phones to FXS ports on your Asterisk server. When the FXO module in your Asterisk Server receives the voltage, it will then generate voltage using the FXS module and send it to your analog phone.

Hint: Remember the “to”… FXS = FX(to)Station and FXO = FX(to)Office.
       With “to” representing the direction taken by the signal.

This is the place to go for support.
