To answer the questions Andrew Webb posed:
regards to reflector use?
As far as I know the VE6IPG DSTAR repeater is open to all
As far as I know any one can unlink VE6IPG and move over to another reflector when needed?
A good operator always checks to see if frequency is in use. etiquette
As long as you know how to setup your radio you can unlink and then link to XRF018B, the Ottawa area reflector on occasion should be possible.
When you are done unlink
Other users can connect to either REF or XRF reflectors or for that mater another DSAR repeater when they wish to.
