[UPDATED] The VE3OBI DMR is back online on 442.1375 (CC1) and my DMR page has been updated. Based on conversations so far, it seems OBI will be on the BrandMeister network and is located in the Raglan, ON area.
Currently, there are no repeaters in the Durham area, that are on the DMR-MARC network, as the Toronto repeater has been turned off, due to jamming.
A quick update. It looks like OBI is now connected to the BrandMeister Network.
