ARLP013 Propagation de K7RA

Sunspots continue to be scarce, although numbers have risen the past
couple of days. Several days this week had 0 spots (March 25-27),
but then they rose over the next few days to 11, 31 and 35.
Geomagnetic conditions have been nice and stable, and should
continue until April 6.

Even last weekend when there were no sunspots, 10 meters was active
during the WPX contest. Bill Hohnstein, K0HA of Seward, Nebraska
said that A35RK in Tonga worked EA8TX in the Canary Islands, a path
of nearly 11,000 miles. This was on March 26 around 2153z. Around
that time Bill also worked both of these stations. 

He worked many strong Central and South American stations on 10
meters, as well as ZD8Z on Ascension Island and AH6RF in Hawaii.
Bill also copied the ZL2MHF beacon, which runs 10 watts to a
vertical antenna, and his longest path was his QSO with ZL1ANJ,
7,709 miles, at 1957z on March 26.
