Eddie, I wouldn't disagree with your comments on appropriate use of the list. Actually, at lists.contesting.com, which is where many people would look, there is no description of purpose. It is at ht

If you pass all 3 wires through the toroid, you will choke out all the common-mode RFI currents. That's probably what you want. Of course it means you can't use the green wire as an RF ground anymore

Interesting subject. My questions Does the mfgr say anything about other "after market" electrical installations? (stereo, etc) I.e., are they worried about people screwing with the wiring? Police ve

The only leverage they have is to void your warranty, IMO. Possibly your insurance company would have something to say if you modified your vehicle in an unsafe way and then had a claim. 73 Martin AA

I can't vouch for RS products particularly, but I think the "cordless phone" approach is a good one for RFI considerations. The latest digital phones operate in "networks". I have a 2.4 GHz digital b

Use the 5 GHz phones if you're using 2.4 for ham work, by all means. However, I've had no trouble with my microwave oven or phones when I set up my WiFi on channel 11. (If I hold my phone handset rig

I have seen much of this, too. I found that the older 10baseT (10 MHz) makes less interference. You can force your computer into 10 MHz mode usually, but many Ethernet devices (like hubs, routers, pr
