🚨👽: An unusual data transfer over the US military's shortwave radio network, the HFGCS, has been broadcasting for over 100 hours!! NEET INTEL first posted about it on May 4th. Although many are aware of it, its source and purpose has yet to be identified. The mystery deepens.
The "Professional" Choice in Budget Handhelds: My TIDRADIO TD-H3 Review The world of ultra-low-cost handheld transceivers has long been dominated by the "Old Guard" (Baofeng UV-5R) and the "Hackers" (Quansheng UV-K series). But a new contender has shifted the philosophy of what a $35 radio should be. After an in-depth look at the TIDRADIO TD-H3, it’s clear this is the radio for users who want modern, reliable features without the steep learning curve. Why the TD-H3 stands out: * The Death of the Programming Cable: The standout "killer feature" is built-in Bluetooth. By using the Odmaster app, I was able to program the radio directly from my mobile phone—no specialized cables or fighting with COM ports required. * Native USB-C Data & Charging: Unlike rivals that require proprietary cradles, the H3 features a native USB-C port for both charging and data (CHIRP compatible!). * Superior Filtering: In side-by-side testing, the TD-H3 demonstrated significantly better receiver sensitivity and filtering than the UV-5R, picking up weak signals that others missed entirely. *Built for the Field: It feels dense and well-constructed, featuring a vibrant colour screen that actually stays readable in direct sunlight. The Verdict: If you are looking for a compact, "plug-and-play" radio that bridges the gap between budget clones and professional gear, the TD-H3 is currently the top of its class. It’s my new go-to for portable VHF/UHF operations where ease of use is paramount.
