🎧 Hey y’all, Big Boy here (KB5MIQ), and I just had to share this little gem with you all.

🎙️ Introduction: Why This Video is a Must-Watch

Whether you’re a seasoned ham operator or a newcomer still wiring up your first shack, audio clarity is everything. In this video, Big Boy (aka KB5MIQ) takes us through a real-world test of the LDG Analog Audio Filter (AAF5) — a $149.95 add-on that plugs right into your audio chain and helps clean up your signal like a dream.

I wanted to highlight this video because so many operators, especially those with budget rigs or older models, often struggle with noise, poor filtering, or just plain ol’ audio messiness. This little box is plug-and-play, brand-agnostic, and can make a huge difference.

💡 Expert Advice from Me

As a fellow ham, let me tell you — audio fatigue is real, especially on older rigs. Investing in a dedicated external filter like the AAF5 may completely change your operating experience. The fact that the filter can be used with any radio and avoids soldering in expensive filters is a huge win! Y

If you’re working contests, chasing weak signals, or just want cleaner QSOs without operator fatigue, this may be a solid upgrade for you. This filter can be recommended for any older HF rig without advanced filtering baked in.
