VHF DSC
My VHF DSC Reciever is a Tait TM8100 with the data audio output used to connect to DSC Decoder, as the solent and english channel are close by and I use the reciever to recieve the various DSC messages in the local area at home allowing me to follow the local traffic and with my interest in listening / watching ships it gives reasonable coverage I use COAA DSC Decoder to monitor Channel 70 (VHF DSC)
