First Moon Bounce using Opera

On Tuesday, March 7, *Luis EA5DOM* and *Jose EA3HMJ* made a test using the
amateur radio weak-signal data mode Opera for 1296 MHz Moon Bounce (EME)

Luis EA5DOM posted the following:

We are both using an small 180cm offset dish. Jose is 400w, so he was
transmitting and I was trying to decode. The trace was visible but too weak
for an Op05 decode. So tried Op1 switching band to 70MHz. After some trying
we got one decode at -24dB

2017-03-07 23:31:17  EA3HMJ  JN11AN  EA5DOM  IM98WN  381  70.093  -23
Op1__~24dB

Switched to Op2 and tried some times without success. I was getting
problems to keep an accurate tracking, so the signal was not optimal and
close to the decoding limit

We will keep testing, But at least one decode was worth the effort.
