  • Mi7 Network Update – 2023-07
    Update on changes we have done to our Mi7 network. First up our chat services.  Instead of having BPQCHAT instances on each node then linking each of those BPQ chats we have moved to a single Chat instance in the east datacenter.  So when you connect to any of the 30+ Mi7 nodes and type CHAT you are connected to the single instance via the NETROM network.   This change brings in line how other BPQ based networks have re-tooled chat and linking which now allows us to be connected to the large world wide chat network.  So connect up … Read more

  • New Mi5 Site Pinconning Online
    Happy New Year from all of us here at W8CMN, but we just couldn’t let the year end without a bang so Jeff and Paul went on Saturday, December 31st to install the new Mi5 Pinconning DMR repeater at our new site.  The repeater is on 444.6250+ or the same pair as our BYN repeater.   The antenna is mounted at 340’ AGL and early range checks prove great coverage.   We had planned on working on a new site here today on Sunday but mother nature had other plans so we scrubbed due to inclement weather.  Here is the … Read more
