I am working on my Echolink IRLP node. This is a Ham Radio\/Voice over the internet protocol (VOIP) amalgam. Echolink and IRLP are two different manifestations of this combination of ham radio and the internet. They both can be run off of a linux server. My old one was a Pentium II. I decided to move to a Rasberry Pi for several reasons. One is energy savings. The Pi a Iphone sized computer uses much less electricity. The second is for “fun” and education. I have had to extend my knowledge of Linux a bit and also knowledge of the software to make it go.<\/p>\n

Despite the monumental and well appreciated efforts of those programming IRLP, Echolink, The Bridge, Debian, and Debian on Rasberry, the installation of all of this is not trivial. It can be, what I think of as frustrating fun. The hurdle is a pain until you’re past it. This is sort of a manifestation of hitting your foot with a hammer so that it will feel better when you stop. I still have at least one hurdle left. Then node is not accepting my DTMF commands via radio or a web interface on Echolink. Consequently I cannot call out on this software, but incoming connections are working.<\/p>\n

The basic steps in this are:
\nSecuring proper equipment
\nFormatting your SD Card for you Pi
\nInstalling your Linux version on the card
\nConfiguring your Linux for IRLP
\nGetting a modified IRLP board for the Pi or modifying it yourself
\nGetting or modifying cables to work with the board, the pi, your radio and a USP soundcard.
\nInstalling the IRLP software
\nConfiguring and testing the software. Learning that if you download then you probably need to use aumix to set your sound.
\nReconfiguring the sound.
\nGetting CW ID to work. This means bridging pins 3 and 4 on you DB9 to the radio cable. Hey maybe this is pins 2 and three, look it up somewhere else!
\nFinal IRLP test and then backup_for_reinstall . Save with a name indicating that this does not have echolink installed yet.
\nDownload and install Echolink.
\nSo far the bug I have found is that a file in bin should be in sbin. This was fixed with a symbolic link.
\nHere are pictures:
