    I have been working on a way to use an android smartphone as an echolink sysop node. Currently, echolink has no provisions for sysop on android, but I beleive I have a solution that will allow for a full repeater controller that most people carry around with them anyway. The project is as follows: I have downloaded the USERLAND app, and am running a desktop version on linux ubuntu as a shell with the android operating system still in tact. I have installed svxlink which starts via the ubuntu terminal (termius app actually). I have built a relativly simple circuit to connect the trrs jack from the phone to a Kenwood style mic jack for keying ptt on an ht. The next stage is to implement an rtl/sdr dongle thats on order with a telescoping antenna for a pocket sized repeater. My interest in radio is to do something un-common, as this may be. Any interest in the project? Feedback would really help. 73

    I commend your work ethic and drive to take on such a project. But other than a "I did it because I wanted to do it" I'm not sure that it would pick up much ground in the community unforuntaly. I'm not sure if you know about this or not, but Allstar is a linux based VOIP/Repeater controller linux package. A LONG time ago, someone took asterisk, a free, opensource VOIP phone PBX and wrote some software to interface that to a computer (called app_rpt). That was then merged into a bigger world wide database with some improvments to what we know as today as Allstar. (Then there is also Hamvoip, which is a Distro of Allstar for the Raspberry Pi 2/3/4, with a bunch of pre-configured scripts. It's by far the most popular one.)

    That's not to discourage you from taking on this task. I often thought how cool it would be to have a Sysop echolink node from my phone. But with everything be compile and ran on a raspberry pi anymore... It's hard to keep image pratical.

    IAXRPT works good.

    You can setup a Echolink /R /L node and just connect to it.

    I appreciate ALL feedback on this subject so thanks. I am familiar with the various conventional methods of achieving a node. I own a solar/wind powered uhf repeater system with echolink node that I control with a linux machine (laptop). I have another setup using an old tnc data controller. While these setups work great, it has already been done. To me, radio is all about experimentation as well as making do with what you got. Virtually everyone has a smartphone, and that allows for phone calls, posting on forums (haha), pictures, video, etc... as well as svxlink. All with something that you already have and probobly carry around everywhere you go. I realize that few hams would have an interest in this as even the commercially marketed smartphone/uhf radios and the linux smartphones have all failed with popularity, but I will post updates soon and provide more detailed information should anyone request me to do so. Thank you all for your time. 73 PS, the repeater control functions of svxlink are of equal importance to the echolink node. I feel there are more possibilities.
