Re: 2m SSB /MM from Bass Strait - 22 Dec 2010

G'day Peter,
Thanks for making the effort. Sorry to hear that you were not able operate at the other sked times, it would have been very interesting to see how far south you could have been worked on 2mtr ssb.
I came up on the later sked times but nothing heard.

Thanks again,
