The afternoon around 2030 utc in the west coast I worked a gentleman, I thought was VE6DTX and he gave me a grid at DO81 but there is nothing on QRZ.com.    My callbook with N3FJP gave me FN04.      Though both are new for me, I'd like any confirmation that I worked and copied his call correctly Thank you John N7AMECN87/88 (today)
