I agree with Kevin. He was very carefully not mentioning the RA-35 which is produced by a company under his supervision, but I can! The RA35 and it's successors are absolutely great products! They have a heartbeat monitor that magically ('cause I don't know how) monitor asterisk, and kill the PTT enable if the RA-35 does not 'sense' asterisk. Before I made the switch to DIAL, I was using Limey Linux, the real embedded solution that does not kill SD cards or care how many times there are abrupt power "disconnects", it just works. Mind you, Limey came out and stopped being maintained *before* the CM119 started to get used. But I wanted to see if it would work. In this particular case either Limey or the thin client I was using did not like the CM119 on the RA-35, and after a while, asterisk stopped working... or something. Just so happened asterisk or something other in the thin client USB hardware would die when I am in the middle of an ASL conversation. The RA-35 did it's job, the heartbeat LED extinguished and the node radio transmitted no more until I pulled the power, and plugged the node back in. A laptop with a whirly spinny thingy using DIAL and an RA-35, I'm care free. Until *I* break it. ~Benjamin, KB9LFZ
