Today node 49289 was finished and put on the air. The Pi3b+ and the software started up great. I do not know very much about linux, but I did not need to. The software stepped me through the setup just fine. I did have some help from the guys up in Phoenix area as to the router setup. I built my URI out of a mini sound fob. It had the cm119 chip not the cm108, but they convert the same way. I plugged it into my Maxtrac and all I had to do was set audio levels. I am very happy the way the project came together. Many thanks to the software writers. Great Job.... Walt 49289 WB4LDS
