After doing the course with subzero last year some time it opened my eyes to about how I little I knew about the correct use of a VHF set at the time. Thats not to say I know everthing now.
My radio is always on 16 and my GPS is connected to it in case I need to use the DSC feature.
My initial response was to the list that subzero came out with listing all the stations that monitor DSC. So I sent an email off the AVCG and VMR. Haven't heard from VMR yet.
