Der zweite QTH am Wolzensee wäre viel näher und auch ziemlich praktisch gewesen. Wenn auch nicht so fotogen.
Statt Random Wire für alle Bänder eine Vertical für 20m.
Hat sich ein bisschen gelohnt. Keine riesen Ausbeute aber doch immerhin einmal über den großen Teich.
Für die Aktivierung hat es nicht gereicht. Bin aber auch nicht böse, dass ich hier nochmal hermuss 😀

The peak of the Eta-Aquarids may have past, there are still plenty of rocks around to have some fun on 6m meteor scatter.

As you can see from the Virgo screenshot, there is virtually always a meteor storm going on. It's just that only the large storms that make the news. But we don't need those to have fun on the radio with them.

Almost every morning I start my day with a MSK144 session on 6m, after which I will switch to Q65A-30s if that doesn't net me any contacts.

Continuing from here

So now I have an 1:1 transformer balun based on these instructions (using 20 gauge thermostat wire and an FT-140-43 ferrite toroid) at the feed point of the antenna, and while I'm getting less noise when receiving than before, the SWR plot still looks pretty bad. :blobfoxsad:

Some ideas going forward:

  1. Since the bad SWR might simply be "uneven" (multipath) reflections from the stucco walls of my balcony, I'm thinking it might help to have a Yagi-Uda style reflector on the balcony side of the dipole, as shown in the attached diagram.
  2. Just fucking build the J-pole and save the dipole for later. :blobfoxgooglycry:

What do folks think?

Today marks one of my personal highlights of the teaching year, gathering signals straight from NOAA and turning them into imagery, with the students learning about the material networks that underpin our contemporary environment. Below NOAA 19 11.21.51, confirming it is indeed a beautiful day!
