Anyone out there with 2.4GHz #antenna experience who can help me with this helix antenna?
I tried building the #iceconefeed by DO8PAT, but I can't seem to get a good VSWR at 2.4GHz.
I tried moving and bending some parts that I though affected the tuning, but the dip at 2.174GHz stays pretty much in the same spot.
Also any pointers to literature about these types of antennas are highly appreciated.

"boys can be princesses too" is making the rounds on twitter bc homophobes.
It is, of course, ADORABLE.
#36c3 will be my first visit to Congress. Tips and tricks for a n00b like me are welcome although I'll be going with some seasoned veterans 😊

I never really grew attached to my #ham #callsign OZ3JH. It just doesn't roll off the tongue as easily as I would like. So today I went off and registered OZ9DLP instead - it popped up in my head the other day and wouldn't leave me alone. When I went to check who was behind it and it turned out to be free, I thought "OK I guess that's the one".

We are thrilled to announce we've been awarded a grant by NLnet!
So.... Physical Pong anyone? Dunno why but I just found this really neat.

A request, please boost.
Anyone who does podcasts in the IT/infosec/hacking world... I would like to be a guest sometime if you'd have me...
I need to up BlackFire's visibility, and as such, talking is a great way to do that.
So, if you are ever looking for a guest/stand in co-host/ whatever... I am available.

@drwho Common misconception!
"Absolute fuck" is more parallel to "absolute zero," the point where no more fuck is possible. It's the most condensed, pure fuck possible.
Almost two weeks ago, we officially started the buildup of #BornHack 2019 (Episode IV - A NEW /HOME). Now I'm back home, lying in my own bed, reflecting on all the amazing people, both newcomers and old-timers whom are a part of the BornHack family. Thanks a ton to all the friends I managed to meet over the last couple of weeks, both old and new. You rock! ❤️
