Your phone is constantly leaking your location—and it only takes a $30 USB dongle to see it. The Thought Emporium shows how older 2G/3G protocols expose unique IMSI numbers to anyone with a basic SDR. 📡 🔗 Full breakdown: rtl-sdr.com/the-thought-em… #CyberSecurity #Privacy #RTLSDR

For such a project, I don't think the total size could be a critical issue. Why the youngs like to use so tiny parts (SMD 0402)? It certainly could be a pocket size power supply when 0603 parts are used. I am 45 years old. Am I too old to handle 0402 parts?

Start to build a pocketPD. A pocket-size bench power supply by USB-C PD 3.0/3.1. github.com/CentyLab/Pocke…

check out my mini terminator spent some time over the last few days teaching my reachy mini to follow a face; there is still room for improvement, especially in the tracking algo

HF Report: The sun is looking stable today (SFI 154), but don't get too comfy! Solar wind from a northern coronal hole is due to arrive Jan 10th. Keep an ear out for VE3VSM/HR9 (Roatan Island). He started his activation yesterday and should be strong on HF today.

@IDV_FPV It should work with home assistant.

What’s actually under the hood of the Ultra Low Power Multi-Sensor board? 🛠️ ​I’ve been sharing updates on this project for a while, but here is the definitive breakdown of v1.1.

TCI(Transceiver Control Interface) is so great for working digital mode remotely. No more VB-cable now.

An open-source phased array antenna designed specifically for EME (Earth-Moon-Earth) communication. This is what the future of high-end homebrew looks like in 2026. Check out the hardware: open.space #HamRadio #EME #SpaceTech #RaspberryPi #Maker

RTTY Roundup It's the final day of the ARRL RTTY Roundup.Bands are packed as everyone hunts for those last few states and DXCC entities before the 2359Z cutoff. Log submission: contest-log-submission.arrl.org #HamRadio #RTTY #ARRL #Contesting

@andrew_macrides I think the mod will also works on UV-K5/K6

GPS Mod Quanaheng UV-K1

@DS1UDN better to use it with a tripod..

New antenna. One of my U/V Yagi antenna collections.

@WD9EWK Great radios, but none of them is cheap....

Earlier this week, I worked an ISS pass using HTs without long whips or directional antennas from inside my house. One for TX @ 5 watts (TH-D75), two for RX (ID-50, ID-52PLUS), all with Larsen 2m/70cm duckies. Heard over half of the pass, made 1 QSO near midpoint of pass.

Since the SOTA Challenge is focusing on 2m/70cm, today is the perfect day to build a Tape Measure Yagi. It’s the ultimate "budget" build for the new year—cheap, effective for satellite/SOTA work, and virtually indestructible. Project Link: instructables.com/Tape-Measure-Y…

The 2026 SOTA Challenge: This year’s focus is on 2m and 70cm distance contacts. Time to get those yagis out of the closet and head for the peaks! 🥾📡 Challenge Rules: reflector.sota.org.uk/t/2026-sota-ch… #SOTA #POTA #HamRadio #VHF #PortableRadio

2026, here I come!

⌨️ Calling all student hams! The @ARRL $25,000 Student Coding Competition officially starts TODAY (Jan 1).The rules are live. Time to turn those Python/C++ skills into tools for the amateur radio community! arrl.org/student-coding… #HamRadio #STEM #Coding #ARRL #AmateurRadio

The "Pico-SDR" now improved: The Raspberry Pi Pico SDR is the "it" project of January 2026. Developers just released a new update that allows for better noise filtering on the $5 board. Latest SDR builds on hackster.io/mircemk/pi-pic… Link to original project: 101-things.readthedocs.io/en/latest/brea…

The "Sputnik" Regenerative Receiver project just got a 2025 refresh. It's a classic 40m homebrew build that’s perfect for the winter break. Check out the updated plans: pcbway.com/project/sharep… #HamRadio #DIY #Homebrew #Maker #Electronics

To All radio amateurs around the world... Happy New Year!

📢 Big news for the HF community! The FCC finally released the Report & Order for the 60m band world-wide allocation (WRC-15). A great way to end 2025! Who’s planning to spend more time on 5 MHz in 2026? 📻 #HamRadio #ARRL #FCC #AmateurRadio
