This year we were back to having six RP-1D /RP-2D systems online on area rooftops.? We are having a lot of antenna issues- the Comet GP-95s wobble and the base set screw falls out and they spin and the hardline either fails or falls off.? ?A fix seems to be to add a hose clamp over the set screw.? Four sites are now using Linksys WRT-54GL routers and OLSR software as back ends, and are not on any gateways or the Internet.? We are using DHCP and small subnets, so any ID-1 that comes in gets an IP address in a unique subnet and then it is easy to route between ID-1 attached networks.? ?This provides any to any and one to many for repeater attached ID-1s.? One of the strengths of the DD mode gear besides high power is the ability to support multiple concurrent data sessions.?

We get routine 12+ mile (omni-omni) paths from our low lying data trailer site and remote trucks to our repeaters with minimal packet loss and 100ms rtd using either base antennas or mobile whips on ground plane mounts.? ?Two of (our) DD modules are on the USRoot gateway and we need to experiment with that.? We again ran two ID-1s as uplink radios side by side to two repeaters from our server trailer to support three ID-1s at the remote sites.? Note our remote stations had a lot of trouble with antennas/coax- the quite rare Comet 1.2 SWR bridges would have been useful and avoid NMO mounts.? ?50% of our voice traffic from 140 hams is digital, and that will increase in 2014.? ?
