Santa’s early Christmas present: ufb Aurora again

au-20.12.2015Oh boy, what a great VHF DX day today! Already late morning there were spots on the DX cluster reporting Aurora QSOs some 2.500 to 3.500 km east from here, i.e. between UA4 and UA9. It did not look like we would get something serious overhere. LA8AV popped out of the noise on 2 m via AU around 13z and vanished quickly after. SM4IVE made an appearance an hour later but disappeared afterwards, too. All just in and out. Then the band finally opened a bit more around 14:30z allowing to work the usual suspects in a medium class Aurora opening. GM6VXB/P was a nice surprise again. After having worked Martin from IO57 for a new square last weekend he was now on the Shetland Islands handing out IP90. Had worked that square before but always nice to catch somebody there, does not happen very often. After 16z things got really interesting when UA3MBJ called me with a great 56A signal. Kept the beam dir 40-50° and worked a bunch of UA1, UA3 & UR stations up to 1.600 km distance. That’s when I call it a great opening! 🙂 Would not believe my ears when RA3SI sent LO04PT as his locator, my first ever contact into the LO field on 2 m via Aurora! I had worked a (small) number of LO squares on ES and MS before but never via AU. LO04 was nothing new either but it did provide a new Aurora ODX for me at 1.769 km. 😎

The opening lasted until 20z overhere. Seems it also extended further south in Europe at times as IK3VZO/JN55 reported hearing me with up to 52A while I was working the Russians. After all had settled an Aurora-E opening, i.e. Sporadic-E triggered by Aurora condx, suddenly started providing nice strong (and clear sounding) signals especially on 10 m and to a lesser degree on 6 m. Seems I was not in the right spot for 6 m but caught a few QSOs there, too. Also made a few audio recordings again, see below.

I made some 80 QSOs in total (Elecraft K3, 600 W & 9 ele LFA on my remote in JO73ce). To apply some kind of filter to keep the list short(er) 😉 only QSOs > 800 km are shown:

Having talked about the difficulties of SSB on Aurora in my last blog entry I took the time this time to do some audio recordings to practically show the differences. Please take a listen to the following 2 sound files yourself …

GM8IEM SSB Aurora on 2 m:

OZ6HQ SSB Aurora on 6 m:

Now which one did you find easier to “read”? I’m sure it was the 6 m file. 😉 Both were about equal signal strength. And now compare those concerning readability to the following 2 sound files and you’ll know why I definitely do prefer “brass pounding” during Aurora openings … 😉
