Hi Larry watchers,
Monitored VA3LK last night (010130) from 22.00 till 11.30 this morning
(010131) and saw:
23.00 - 00.12 SO? (end of "QSO?")
01.00 weak dashes
02.20 one dash
02.57 dashes
03.31 dashes (part of "CQ VA")
04.05 3 (middle char of "VA3LK")
05.30 one dash
06.00 - 08.35 CQ VA3LK QS
08.35 11.30 nothing
In the range 137787 to 137790 Hz, there are 4 other signals at:
137790.0 Signal A
137789.8 Signal B
137787.8 Loran
137787.4 Signal C
Signals A and B are probably from distant broadcast stations, since some
sort of modulation can be seen on them. They were strongest at 02.00 and
03.00 and at a steady slightly lower level from 04.30 until 06.18 when they
disappeared simultaneously with a big drop in QRN(QRM?) Signal A is slightly
weaker but they follow the same pattern of strength.
The Loran line is strongest during the day time and weaker at night with
dips at 04.00 and a big dip at 05.30, but then recovering strongly.
Signal C is only seen at night. It was strongest at 01.00 and disappeared
suddenly at 06.18. The pattern of changes in strength is different from that
for Signals A and B.
I will post some pictures and graphs on my web site:
