10m has been on fire today! I managed to make a few contacts here and there throughout the day until it faded down later in the afternoon. It seems to be picking up a bit again now.

@graffen Great Sunday afternoon #Cryptohagen. I counted 15-16 paticipants today - or maybe rather 15 1/2 or 15 1/4 depend on how you count a baby :-D

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.

Fellow , if you use , _please_ check your mic gain, chances are you need to turn it down a notch. There are so many _extremely_ loud stations out there, it's uncomfortable to listen to.

"boys can be princesses too" is making the rounds on twitter bc homophobes.

It is, of course, ADORABLE.

Hoping to meet some fellow enthusiasts at too. I'll bring my radio and will probably be lurking on simplex 433.450 cc1 tg99. Callsign OZ9DLP. DMR ID 2384316.

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 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".

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.
