I am not sure where to post this so I thought I'd ask here and get a referral to a more appropriate list ... Why is it that late in the afternoon a BC radio station on 1450KHz wobbles and 970KHz does
I used the wrong term, am distracted here and brain isn't pulling up the correct term! It is that usual late afternoon/early evening sound common to AM signals - kinda distorted and drifting - it's n
Is there any reason to avoid dual-connector pairs for Amateur Radio apps? I recall reading somewhere that there may be a problem tapping both for various uses in Ham apps. It seems that they are part
So to eliminate the "flutter" (that's the term I was struggling for, thanks) - I need to try some sort of directional antenna and/or perhaps a nulling system (active or passive)? -- Thanks! & 73, doc
Turns out that the problem was mostly at the dash switch. I had to pull the dash to re-run the AM/FM radio antenna cable and in so doing discovered that the cable connector to the switch was barely h
Touch-control lamps have long been on the short-list of RFI-vulnerable and RFI-generating devices. I have copied this to the two RFI-related Ham lists. -- Thanks! & 73, doc, KD4E Personal: http://bib
Just curious ... Are the Dunestar and W3NQN filters also 150W max., same as the ICE models? -- Thanks! & 73, doc, KD4E Sent Using: ChurchPup-Linux http://www.churchpup.com/ Personal: http://bibleseve

Since they just ran a Bright House cable next door in our *very* rural neighbohood (10 acre lots) to a pole that is about 120 feet from the house should we anticipate a rise in RFI? If I we to allow
Bright House is cable. I have no idea as to what spectrum or power level they pump through their lines to get signal here. We are in the woods and their line runs close to a mile from the nearest sma
I asked them to mail ours to our PO Box and they refused. Rant on! Our mailbox is 1m from the house and subject to vandalism, but bureaucrats cannot think or act outside of a tiny mindless box so to
The MPI-150 150W modified sine wave inverter is on sale for $15. Anyone tested one for RFI? -- Thanks! & 73, doc, KD4E Free OS : http://www.ChurchPup.com Based on: http://www.PuppyLinux.com Personal:
Anyone know if the electric cars are RFI noisy or clean and if they are vulnerable to near-field rf? Living in the sunny south we are seriously considering an electric car - free recharge via the sun
I wonder if there are specific brands or models that are using noisy DC motors and others that are not? Or perhaps it is the computer or other circuitry unique to certain cars? I wonder if they are s
You can also buy your own OBD II scan tool pretty cheaply online or at discount places like Harbor Freight. Since we also have a Chevy van and plan to go mobile I'd be interested in what you discover
I raised my delta loop *from* a feedpoint of 6' above the ground *to* 15' and now it is getting into the TV (all channels). The TV antenna is at 30 feet and is about 30' from my 6M antenna. (I am run
300 comedians out of work and Bud has to start! ;-) I am only in my 3rd week on 6M and am loving it, WAIT????? Only thing I can barely wait for is the next opening! -- Thanks! & 73, doc, KD4E Have yo
Lots of great assistance already, thanks! Here are some additional clarifications ... 1. The interference is on all TV channels, VHF & UHF. 2. Removing the distribution amp eliminates both my desirab
It is only getting in via the TV coax. Our home is all-steel, walls and roof, so there is nearly zero chance I am getting into the amp any other way - indeed when I disconnect the antenna feedline an
The amp is followed by a splatter, I probably should label the amp as a splitter pre-amp - it does not provide multiple outputs. We are in the woods and without both the antenna AND the amp we only r
