Topband: JA pile-up 01.01.2008

Hello,

Sorry to be late sending this report but, thought to be interesting for propagation enthusiasts. On the first evening of this year (2008) it was a very good opening toward JA from my side. With my modest set-up (INV.L 15m-vertical about 35m-horizontal TS450 with 100W) I never heard such JA pile-up on my CQ. 31 JA station were in the log but could be more without QRN...Again I see that a quiet receiving antenna is necessary for "high quality" operation. Here you can listen to how it was:

Sorry to the sound quality but my laptop's sound card is not so good. Also, there were a big QRN at that time, thanks to the INV. L antenna:) The fact is that much of those signals were S9 to me. Was the first time when I hear JA with S9 I couldn't believe to myself that this is possible...especially with an INV.L. The "show" in the upper recording start at 20:29UTC and end at 22:48UTC (JA's dawn). The whole "show" end at about 22:05UTC when the JA's dawn end. Again, the "propagation enhancement" at dawn is confirmed. The problem is that this is not the case all the time. Being QRV for two full weeks around the winter holidays I notice that the good propagation is present for much more time than we think but there are no hamradio QRV! Because of that, again, I suggest that a beacon is the most adequate tool for one who want to study the propagation's phenomenon.

All the best and hope to hear you on the band.
