EME Moon Bounce on 40 meters?
Rick Shepherd, KA8ERS and four other Amateur Radio Operators, K9JCM-Jim, KE5RJX-James, KC2ZUR-Rich and KA1FFY-Ron operating 40M SSB claim to have bounced their signals off the moon.
"Can you hear me now?"
If not wait 2.6 seconds and you will.
On April 11th 2011 at 12:05a.m. Rick, KA8ERS asked the guys to stand-by, He thought He heard another station trying to check-in. It turns out it that it was an echo of His signal. To travel long-path around the earth it takes 134 milliseconds. It takes 1.3 seconds to get a signal to the moon, another 1.3 seconds to receive the signal back (2.6 seconds total) once a successful bounce has been accomplished. Rick and the other four radio amateurs in the QSO confirm that there was a considerable delay of all their signals. They measured it to be just shy of three seconds.
The echo's were recorded by K9JCM-Jim. The moon was in the N.W. sky at about 50 to 60 degrees from Rick's location. They were operating on 40 meters 7.190MHz between 12:05 and 12:20AM EST. Other stations that have confirmed hearing the echo are KJ6LJB-John and KF5KJE-Robert.
Anyone who has experienced echo's on HF or has other information about long delay echos is encouraged to contact Rick at: rsheph (at) columbus.rr.com
If you have recordings of this QSO or similar echos, please share them with Rick, KA8ERS.
