[Moon] First 23cm echoes

[Peter Sundberg]

Congrats Jimmy, and welcome to an EME band full of excitement!

I am sure you will enjoy the fact that random operation is King on 23cm
EME, and there is an endless string of new stations coming on the band.

GL with fixing your minor problems, looking forward to work you on CW EME
for our EME-band #3.
