Colorado: This morning I started calling CQ around 0550 local (12:50Z) time and managed to work a few JA stations, HL5IVL was also around, all signals were 4x5, rapid QSB was again prevalent.
I opened up the DXMaps website to see what others were hearing and saw that JA1LZR had logged my signals over a period of nearly an hour as follows: 3dB @ 1320 Z 6dB @ 1332 5dB @ 1346 16dB @ 1359 17dB @ 0712 The very rapid signal rise at his end shows there was significant signal enhancement which was not reciprocated at my end, what few stations were audible were well down in the noise. Unfortunately I did not see any further spots despite continuing to call CQ for another 30 minutes into broad daylight, I would have liked to have seen how quickly signals decreased, the signal path was shown as just over 9km. Interestingly, KH6LC had also provided spots over the same period which showed a signal variation of 6,8,7,6dB on a path length of 5km , he is just South of West from here, JA is NW. Several spots from W6/W7 stations showed a decrease of 1 to 3 dB over the same period. 73 to all. Dave AA0RS _________________ Topband Reflector Archives - http://www.contesting.com/_topband
