⏳ Few seats left: @PentHertz LoRaPWN: From Custom/Industrial to Drone Hacking starts in 1 month at @hardwear_io 🇺🇸. SDR-driven. 4 modules: → LoRa PHY SIGINT & decoding → LoRaWAN crypto & infra attacks → Meshtastic keys & topology → ELRS drone C2 & telemetry Included: RF Swift image @hydrasdr RFOne 433/900 MHz / 2.4 GHz antennas.

Perfect SilverSat SSDV pass over the Eastern U.S. @hydrasdr RFOne 2.5-turn helical omni had no trouble w/ the SSDV stream repeating Image-29 frames until complete. Fun watching the pic construct in real-time w/ 'feh' viewer!

Realtime OBZP1 reception and decode with my EggBeater -> Spacewalker LNA -> HydraSDR RFone combination. network.satnogs.org/observat… @R4UAB #satnogs #cubesat

Thanks to very active HAB guys in Maryland, it's a beautiful day to track Amateur Balloon payloads! Even 1.1° elevation is plenty for a weak-signal mode like the 4FSK Horus modulation. 2.5-turn helical omni antenna brings in the signal to the @hydrasdr RFOne just fine!

35 dBm (HydraSDR RFOne) vs -11 dBm IIP3 is a ~46 dB gap in linearity. That's not a spec sheet detail it's the difference between a drone link that works near a cell tower and one that doesn't. 40 MHz is useless if one strong interferer drives the front-end into compression.

Thanks, great image received and decoded network.satnogs.org/observat… using the HydraSDR RFOne and a diy EggBeater

HydrSDR RFOne support for 433 called hydrasdr_433 github.com/hydrasdr/hydrasdr…

🚀 RF Swift images v0.1.3 out! Updated Ghidra, ImHex, RF tools new libhydrasdr v1.1.0 for HydraSDR RFOne and our special SDR package & more! rfswift.io

libhydrasdr v1.1.0 major upgrade for HydraSDR RFOne ! Hardware-agnostic API with automatic DDC decimation: sample rates from 78.1 kHz to 10 MHz, HD mode, lock-free streaming & ~2x performance boost. Try it now in SDR nightly ! github.com/hydrasdr/SDRPlusP… github.com/hydrasdr/hydrasdr…

What a wonderful session. It gave me just the right push to create HydraSDR RFOne support for the VRT-IQ-TOOLS. Created hydrasdr_to_vrt, lets say alpha release.

Received with a HydraSDR RFOne SDR - GPSDO Locked clock. IQ replay SilverSat observation and decoding the image taken by the satellite. #satnogs #amsat #cubesat

We are already in contact. In fact I have an RFOne that they sent me for evaluation. I'm yet to find a project to use it. Do not take this as any criticism of the RFOne, but rather as a statement that I have too many other SDRs lying around.

May I suggest that you and @hydrasdr contact one another, There is also GNS development being done with the RFOne github.com/AgileEngineeringL…

SDRTrunk now supports HydraSDR RFOne natively ! Nightly builds available for Windows, Linux & macOS. Requires firmware v1.0.2 (with official HydraSDR RFOne USB VID/PID) github.com/hydrasdr/sdrtrunk… #SDR #RFOne #HydraSDR #sdrtrunk #RadioHacking

Greate development, Ais-catcher supporting HydraSDR RFOne github.com/jvde-github/AIS-c… #hydrsdr

SatNOGS Client 2.1 docker container updated with gr-satellites 5.8 and @hydrasdr RFOne SDR support. #satnogs #sdr

RTL-SDR V4 is good. Bundle antenna is ok for regular FM reception and playing. Better antennas are needed based on the intended use (e.g. ADS/B, directional 433, etc). You can also use ANT-500 from GreatScottGadgets as a general purpose telescopic antenna. If you want to upgrade to a more robust RX-only SDR, I would suggest any of SDRPlay RSP1B, AirSpy R2 or HydraSDR RFOne. I have all and each has their own pros. (one selling point of HydraSDR for me is the USB-C connector) In summary: learning SDR as beginner: RTL-SDR. Better option: any of those 3 (I rarely use my RTL-SDR these days) Here's a size comparison:

Thank you SatNOGS developer team, we now have the first SatNOGS-client 2.1 docker based HydraSDR RFOne observation network.satnogs.org/observat… #satnogs #hydrasdr

Missile Defense Agency ... grok breakdown- "The MDA's SHIELD Multiple Award IDIQ contract, announced on December 2, 2025, qualifies 1,014 companies for potential task orders under the $151 billion ceiling over 10 years, focused on layered missile and air defense (including UAV integration for surveillance, counter-drone, and hybrid threats). No full public list of awardees exists yet—federal databases like SAM.gov and FPDS.gov update gradually, and news sources confirm only a handful of majors. Based on deeper searches across defense news, contractor announcements, and MDA histories, I've expanded to all verifiable or highly likely public drone/UAV firms involved in relevant tech. These are major DoD/MDA partners positioned for SHIELD task orders. No specific per-company funding has been disbursed; it's eligibility for future awards (base period 3 years, options to 10 years)." $AVAV Key drones/products: Switchblade loitering munitions (kamikaze UAVs for precision strikes), Puma AE small reconnaissance UAV for ISR (intelligence, surveillance, reconnaissance). - Involvement/contract: Confirmed MDA contractor for counter-UAS and missile defense prototyping; eligible under SHIELD for air threat layers.
