This product you already know that they are used for since you know what it is. You can rely on them! As a result of RF in the shack affecting my PC and causing WSJT-related problems, I had to turn off my PC. I hit a wall when I ran on 40 meters, causing X to crash. The ferrite chokes on the coax worked well with a few watts of RX power but provided limited success over a few watts of TX Thus, I bought a couple of them and wrapped the USB cable from my IC as follows My PC is connected to my 7300 via one of them. That was the solution to the problem! In a similar manner, I used the others on the power cables for my laptop and my rig. The product worked so well, I bought several more for insurance purposes. I have not tried it yet, but I am told that they are equally effective if you have unwanted RF (from or into) other electrical devices in the house.

Done and dusted. Interference is no longer an issue.
I got rid of a RF issue.
Here are two nice 2s I made. The baluns will be used on loops spanning 80m and 20m.
That fixed the problem and the hum was gone from my remote speaker on my VHF rig and my remote speaker on my remote scanner. This is something I'm going to order more of.
A best toroid core for producing baluns in Ham band. When I have 1500 Harddown in my system, I use 3.
This is very good. It is the power cable that I used with my Samsung tablet. SO I THINK THE INTERFERENCE IS COMING FROM AN ADDITIONAL DEVICE. IT WORKED THEN IT DIDN'T, SO I THINK IT IS AN ADDITIONAL DEVICE.
I purchased this to suppress RF. It worked perfectly. I felt the prices were a bit high.
