LOW COST CW FILTER OPTION FOR OLDER RADIOs

🎙️ QRP Ham Radio, CW Operations & DIY Gear Reviews 🔧 | Hi-Per-Mite CW Filter Demo

Welcome to the channel! In this video, I take a closer look at the 4 State QRP Group’s Hi-Per-Mite 200 Hz CW Filter — a low-cost, high-performance CW audio filter perfect for older ham radios that lack built-in filtering. Whether your rig doesn’t support CW filters or they’re no longer available (or just Unobtanium due to price), this filter is a great solution.

The Hi-Per-Mite helps remove static noise and adjacent station interference, improving your ability to copy weak CW signals in crowded bands.
