Ch A2 F2 strikes again ! San Antonio, Texas 78228
CST used
Feb 14, 1982: during an intense 50-MHz F2 opening to the Caribbean
and northern South America
Ø=190 0957 - what looked like half-frame color bars
A(Bo)=42 with the white-square under them (due to the
multi-path ghosting unable to "count" the
position)
1015 - other station with programming now CCI to
the CBars; original station begins programming
but unable to read any printed material due to
ghosting
1022 - fading sets in rapidly and soon total loss
as in most previous events, the MUF did not reach the TV audio
frequency. As before, the classical situation of multi-path
and relatively slow fading were dominant. This time I did get
a chance to take one 35-mm frame of the CBars.
THEN: an unsual resurgence 50-MHz F2 opening to essentially
the same regions as the morning event
1517 - rather fast fading multi-path programming without
any audio; unidentifiable
1528 - CCI rather heavy (hi-offset pattern)
1540 - at least 2 strong signals with mixed programming
1544 - intense multi-path ghosting
1552 - rapid f/out
the fading on this was considerably deeper and more rapid than
the morning event; the multi-path character and the lack of any
audio MUF pretty well confirm it as being F2 (along with the
simultaneous 50-MHz events)
Feb 17, 1982: a relatively modest 50-MHz F2 opening to the Caribbean
Ø=167 and nothern South America
A(Bo)=28
0915 - (and prior) multi-path ghosting very evident;
no audio; programming but unidentifiable
0920 - rapid QSB onset
0925 - almost the impression of some Es mixed in now
0940 - rapid f/outs
Feb 18, 1982: a protracted but not particularly intense 50-MHz opening
Ø=170 to northern South America
A(Bo)=18
1610 - multi-path ghosting, QSB; no audio
1620 - possible mixed programming; unidentifiable
1625 - rapid decrease in intensity
1630 - complete f/out
The events of the 17th and 18th are not as completely clear-cut as those
of the 14th. However, the concurrent 50-MHz openings along with the
lack of audios and intense multi-path ghosting make them very likely to
have been F2 in nature.
