I found from AliE SE2576 2.4 GHz Bi-directional 1W amplifier and build around it QRP QO-100 Pluto rig which you can use also for 2300-2450 MHz tropo QSOs. I tested my new rig for QO-100 FT8 uplink using AliE PCB-logperiodic antenna, yes it works also with QRP antenna.
Starlink patent US12003350. Two interesting findings: (1) A single OFDM modem architecture is used across terminals, satellites, and gateway—a bold break from traditional satellite design. (2) “CFR” in the Summary may be a typo for Crest Factor Reduction. https://t.co/QMzv6oYuxt
Introducing Sakana Fugu: A full multi-agent orchestration system accessible via a single model API.
Our ‘Fugu Ultra’ model matches the performance of Fable and Mythos, delivering frontier capability without the risk of export controls.

$250,000 military radar, now open-source & buildable
Bro built OpenSource Military Radar that tracks multiple targets up to 20km away.🙌🏻
One person built what defense contractors charge a quarter Million for and Everything open: schematics, PCBs, FPGA code, GUI
AERIS-10 : schematics, PCB layouts, FPGA code, python GUI, everything under open source 💀 commercial phased array radar starts at $250,000.
- 20 km multi-target tracking
- Electronic beam steering @ 10.5 GHz 🙂
- GaN amps & real FPGA Doppler processing
- Full electronic scanning, Doppler, pulse compression
- Full signal chain on Artix-7 FPGA
Military surplus is $10,000-50,000 but its decades old analog junk with no electronic beam steering
this’s does electronic beam steering at 10.5GHz, pulse compression, doppler processing, multi-target tracking on a real time map
two versions: 3km range with patch antenna array, 20km range with 32x16 slotted waveguide array and GaN AMPLIFIERS
customs frequency synthesizer, 16 front-end chips, FPGA doing all signal processing, GPS and IMU for ACCURATE target coordinates when the platform moves
All gerber files included so you can order the PCBs and build it yourself
