If you have long runs of coax cable hooked to a monitor you can actually visualize the common mode ingress watching the hums bars roll across the screen. The 60 hz bar intensity may be directly rela
you can hums bars roll related to Unfortunately this doesn't apply at all to HF receiving. It only means something at 60 Hz, where it affects video. On 60 Hz the cable shield is not several depths t
Tom, For the purpose of dealing with signal ingress, would not the Faraday Shield cure work on 1.8Khz as it does at 60 hz? Herb Schoenbohm, KV4FZ _______________________________________________ Topb
It not the Faraday I think you mean 1.8 MHz Herb, in which the answer is no. While the physics is the same, the frequency is vastly different. The scale of what we are looking at is off by a factor
,,,Those hum bars are for a large part caused by For safety reasons, power line neutrals should only be connected to power line loads. Any other connection is a ground fault and is dangerous. The pow
