1559 Just saw the carrier wave appear, about an S4.
1607 Now S9. Perhaps they are still tuning up.
1622 Now hearing 1 second pulses.
1650 Now hearing... CHU?
1703 Now hearing... Brother Stair. Someone is having some fun with us. I think.

I wonder if they ever do hf moonbounce with that thing?
Like how haaaaarp did on 40m cw? I got a demo of it somewhere.

It is on 5095 now as of 2325z.
Still on at 0021z with about a one minute on / off duty cycle. S9+40 here!

Folks,
I think I received Arecibo on the night of July 31 2017 on 5125 KHZ sending a carrier for 4 minutes on and 4 minutes off, cycling that way for the hour (more really) that I listened. 0612 utc to 0736 utc.

I am quite sure it was Arecibo because it was the strongest signal on the air at this QTH.  Moderate fading from time to time but never ever got close to the noise floor.  :-)

So does this sound right ?  I didn't record it because... well... it was just a carrier...
