Hello Tom und Yuri:
I have experienced ducting on 75 meters. I was tunning the band,
about 1500 hrs local, (0800z). I came across a ssb station in qso with
his friends on the eastern seaboard. Since he was the only stateside
station I could hear, I read the mail for a few minutes, until he signed.
He was a W4.../KP4 Mobile, in down town San Juan, Puerto Rico. I suspect
he was near the harbor. My location was 30 miles east of the islands of
Mindanao and Ceyte, enroute from Singapore to Midway Island. I was using
a TR-3 into a inverted L antenna. (the emergency antenna). Now I would
say that was a good haul for a mobile on 3970 kcs. It was 0200 local PR
time. Not sure which way the transmission propagate. I was about N10
Lat. E130 Long. Another thing that I remember , I could only hear one
shore station that was close to the US and that was Balboa, Canel Zone.
I sent my CW tfc through him to lessen the handeling charges for traffic
to the uSA. I was in daily contact with him all the way from Bombay to
Singapore. Didn't hear any of the Coast stations in the uSA. I would
say that there is some ducting, east/west along the equator.
Next big ducting event, was when I was approaching Cairo, Egypt a
DC-7. We were at 18,000 feet and descending and just made a frequency
change as directed by Cairo air traffic control. Frequency near 120 Mhz.
Upon the frequency change, Cairo center was being ORM'ed by a TWA flight
calling Cleveland center. Yeah, your right, I called the TWA flight and
we exchanged our locations. He didn't QSL.
That's my big experience on ducting.
72's and Good Luck in the Contest.
