It's back! About 6 months after closing down the network, Kelly Lindman of Sweden brought the network back to life. Now run as a no-charge private network, many of the radios on the system are back again. Currently Kelly has capped the membership to the network, but expects to open it back up in the future.
My node, the Pennsylvania DX radio, is back - this time with an Icom R-75 receiver replacing the former IC-718 transceiver which I plan to use for ham radio purposes.
