As we continue to grow we are committed to using Allstar. But we are already at a loss as to how to put multiple repeaters on the air from the same site. Sure, we can use multiple URI’s I think and a single PC. But we prefer RTCM’s and they cost $$$. The real question is the use of external controllers like an Arcom RC-210. They have 3 ports plus a 4th basic port. We have 2m, 440 and 900, plus a WX receiver. URI’s are cheaper but if we do the PC approach can we declare separate config files/directories, or would we need to install something like OpenVZ and mount each USB device in separate containers? PC’s at remote sites concern me especially without redundant power supplies. A RC-210 would allow the use of only one RTCM and the ports would be linked to through the RC-210. One node number for three repeaters, although that isn’t my preference. How much audio delay could be expected using an external controller? Thank you in advance. Wayne
