[ADXA] gotta brag a little....

Thu Nov 21 09:08:37 EST 2019

I had the opposite problem as San - I was going to broadcast out a big
Yee-Haw! to the moonbounce story but instead of going to the ADXA list it
just went to Dennis.

I make a habit of looking at the "TO" field but sometimes I forget.

I had a smaller moment a couple nights ago, working TK/S57C on 40. Yeah,
big whoop, but the thing was I was using my all homebrew rig so that was a
kick.

I'll probably stick to the K3 for CQ WW though, to improve my chances.

Looking forward to seeing everyone at the big gathering. Great talent
line-up.
