I'm a cybersecurity professional, licensed amateur radio operator, and tech enthusiast. I also make music and burn my fingers with soldering irons.

Sigint and technical rabbit holes turn me on.

I usually follow back if I see proof of life. :)

Yesterday evening I removed some cabling from my SDR set up and put a DIY 1:1 balun in where the active loop outside feeds into its Bias T. I have effectively eliminated all the flying birdies. Everything left is either from the Raspberry Pi or the SDR itself. Win.

A fast beacon, Radio Marti, and an EAM all in one waterfall. For your viewing enjoyment.

EDIT: That "fast beacom" may be more than just a beacon. It has some features to it that are more than just the beeps, some tones appear in the spaces between the beeps. I don't see any good explanation on the web yet but I do think it is military.

I'm not 100% familiar with the frequency of "Sky King" Emergency Action Messages but it seems like they're going crazy today. The one I'm currently listening to, "invictus," sounds suspiciously like it's from an airborne source given the high frequency hum and people talking in the background. I heard at least one "shit."

I moved the Raspberry PI running my SDR/RTL-TCP shortwave to my Solar panel and now the birdies are really happy! They're flying around. Ooof.

If this is Radio Republica broadcasting to Cuba from Issoudun in France on 9.49 MHz AM, they have a transmitter problem I can only describe as "WTF that sounds evil."

Oh yeah look at that WAR MACHINE GO!!! OOOOO RAH!!!!!

I thought I might need to rotate my loop antenna but nah.

The Dow was supposed to open up higher today on "investor optimism." Cue sad trombone.

Very strong data modem transmission at 14.85 MHz. Gonna be military. Houston, TX.

Another Military ECCM HF FHSS signal. This one is really wide and seems to invade into the 31-meter broadcast band.
