OARC members operated from Canada's Cold War Museum, also known as the Diefenbunker, using the call sign VE3CWM. As Dave Green (VE3TLY), Contest Captain explained: "the 2015 activation of VE3CWM is our best yet from the Diefenbunker." A quick summary of the claimed results are:
By far the most active bands in 2015 were 20m phone (200 QSOs), 20m CW (189) and 40m phone (178).
To put things into perspective, here is a comparison with the OARC's previous best results:QSOs 967 
Thanks are due to the management and staff at the Diefenbunker who agreed to open the facility well beyond regular hours to accommodate us. Photos are by VE3YTZ.Greg
