Cure For Stray RF On My Signal

Cure For Stray RF On My Signal.

I found a simple cure for stray RF on my signal. At $10 the fix is cheap!

Occasionally with different frequencies, weather and beam headings I’ll get RF in my shack and onto my signal. If my microphone line gets near my Palstar AT5K tuner, or if I’m beaming 8 elements over the house on 10 Meters, or RF is being introduced into my W2IHY cabling and/or gear, there’s nothing more frustrating than hearing RF on my signal – no matter where it’s coming from.

I’ve installed dozens of choke beads on cables & leads and although they do work, they’re “fussy”. I’m always changing positions, wraps, adding/subtracting and moving things around to try and diminish stray RF it seems.

And now here’s the $10 permanent fix for stray RF on my signal: https://amzn.to/3HkRg2M

This little Besign isolator/decoupler COMPLETELY removed any and all stray RF from getting onto my signal!

I simply plug my Heil headset into the Besign and plug the Besign into my radio mic input. It couldn’t be easier. This isolator decouples whatever stray RF is on the mic line. No stray RF in, no stray RF out.

It also works on decoupling hum from a pole pig transformer in a linear amplifier I occasionally use around here. If my headset mic is within 2′ or so of the amplifier, my mic picks up the magnetic flux “hum” from the amp transformer. This Besign isolator removes 100% of that hum too.

And to add to this post, I just heard from a Ham friend in Florida who was getting RF into his Heil amplified speaker on certain frequencies. He installed the Besign isolator and reported back the RF is completely gone!

“Thanks for the tip Lumpy. I Was getting some RF into my Heil amplified speaker. Inserting toroids helped, but the gadget you recommended completely removed it. Two thumbs up!”

And that’s that. Easy, simple, cheap, and it works! https://amzn.to/3HkRg2M
