RE: WD9EWK from Dayton (18-22 May 2006) - long


Great job. Keep it up and let us know how the mobile SSB/CW project goes.

Out of curiosity, any new satellite stuff or announcements form vendors at

>There was a church just on the Indiana side of the state line, and a

>(0230 UTC Monday), and I made 5 contacts from this spot (grids EN70xr

>About 40-45 minutes after that AO-51 pass, around 11.15pm (0315 UTC
