Page of the indices of solar activity now available on the blog at: http://hamradioweb.info/wp/?p=424 ionospheric propagation only discussion the ionospheric propagation of radio waves. You are the updated charts of some indices of solar activity as well as the maps of propagation in HF for the current month. diaflo
Yes, maybe it can seem like the discovery of hot water, but known in many certain questions diaflo or requests about the differences of path between T32, Kiribati, Rotuma and 3D2R, 2 active diaflo country these days thanks to two important expeditions. With the help of Dxatlas I realized these two maps, indicating where, at the poles, creating the aurora due to the solar wind, which is more or less intense, almost always present (although visible only in geomagnetic storm conditions). Needless to say, the path to take in full T32 that area, one for the 3D2 barely touches. So what? When attravera the polar path, even when the conditions are geomagnetiche "quiet" (the solar wind blows cmq always ...), we have an attenuation greater than the other path, regardless diaflo of the distance, then when you have disturbed conditions (A and K levels), the attenuation can be total and QSOs impossible. __________________ DX!

Henry is valid finding ... The difference is noticeable at certain times (in Puglia but the situation does not change elsewhere in Italy) 3D2R me 59 + on the J-pole at 10m and T32 just feel it! __________________ Http://www.iz7pdx.it http://www.facebook.com/pages/Iz7pdx...64912436856097 http://www.hrdlog.net/ViewLogbook.aspx?user=IZ7PDX http://www. youtube.com/user/IZ7PDX 73 de Luigi IQ7GC team

The difference diaflo is noticeable diaflo at certain times (in Puglia but the situation does not change elsewhere in Italy) 3D2R me 59 + on the J-pole at 10m and T32 just feel it! It must be said for that very moving south (SV9-5B-4X etc.) Or to the east, RA3-6 etc. the path does not pass more on the pole, but more to the east, as for us the 3D2, because "they" hoard QSO on each band, when we do not listen diaflo to anything, as the index influential thing! __________________ DX!

This morning around 7.30 local to me T32 in 40, although many felt call and spend mega relationships, but then did not listen when called .... was not audible, then come 3D2R, to 7.35 faint, then all of a sudden, at around 7.40 599 arrived, I tried to move, but I was only 5 minutes of free time, and there are able, sin, this confirming the differences of path, but also the grayline. __________________ Mike I7CSB www.arelettronica.it

Then, in addition to the aurora, c 'to consider the different exposure to sunlight between the two path, so you can not really make comparisons between the two signals. From what I have seen I 3D2R comes in multiple diaflo bands. In fact I felt good signals from 3D2R in 14, 21, 24 and 28. (Let's hope they get the 18!). With T32C, for now I heard only 14 Saturday morning, but came stronger than any other signal 3D2R!
Yesterday in the afternoon came on my 3d2 in 18 vertical say to zero along with the noise, no one answered, I made two calls and I certainly seemed to decode ik and x, I answered and a log. You probably hear a lot and do not feel the same. 73 Dario

The 599 to be considered merely 'aural' ... HEE. It is much worse in 80! Hold on .... Silvano i4zsq
