Aaron, I found the better option in my case was a 1:1 flux coupled transformer using a ferrite core placed at the *receiver* end of the coax feedline. Background: I had noise up the wazoo before put
Frank, Thank you for your comment, but, there is an additional factor not considered: The capacitance of the coax cable's shield to ground (I mean the EARTH over which the coax cables lays.) This fo

Get your Astron transformer PS's while you can I suppose. Mine is 40 +years old, (RS-35M) still running strong. Gary...wa6fgi Dave Hachadorian, k6ll Yuma, AZ --Original Message-- From: Joe Sent: Satu
Took a quick look at the referenced file link, I see all kinds of "efficiency standards" but not one word regarding RFI issues. Gary...wa6fgi Dave Hachadorian, k6ll Yuma, AZ My first thought was, is
Jamie, I, too, would like to know what it is that 'goes bad' in these cap banks. I have several in my area that are, or have been, noisy. In the past, the power company pulled the line fuse to tempo
Joe, Typically, in our area they look very similar to this: https://www.flickr.com/photos/31462250@N03/3799973224 The thing with two high voltage leads going to it are a series switch so the cap acti
Thanks for this. I've starting to have failures of 90W incandescent floods in recessed cans in my house and am considering LED replacements throughout (26 of them) Longer life and cost savings are
Minor correction: The new ham band at 630 meters is slated to be 472 to 479 kHz. I am presently a Part 5 experimental licensee (WH2XQC) for this band. At the time the new 630m band opens, an allocat
Mike, You might want to take a look at this group. They are very active in locating and resolving all levels and sources of RFI. What you are talking about regarding solar panels is a hot (?) topic o
Just checked my up/down speeds via speedtest dot net, dl was 100 mbps, ul was over 7. I have Comcast cable, they can do this `cause the signal is delivered via rf. Fwiw, I also have their fone servic
How is your station grounded? Trusting the old "attach it to the water pipe, that'll be fine"? Sounds like ground looping to me. Most ground looping problems, to me this is what your describing, can
Better 'grounding' ... I like. It means even greater "displacement currents" are induced in equipment when said equipment is in the high-intensity E-field of the antenna (maybe twenty or thirty feet
This is great news that both the cause was located, and that the FCC is taking action to get Solar City to resolve the problem. I wish you well, but fear for others who might some day find themselves
Of course it is. It forces common mode current toward zero, leaving balanced differential currents in the two conductors. What more should it do, make coffee too? Balun is short for Balanced to unb
Can I just "push this over" the absurd edge (b/c I don't think we're in Kansas working at the Bendix-King plant anymore)? I don't want a 'voltage' or 'current' balum, I want an RF POWER balum. (missp
Pete, Sounds like the perfect job for my first choice in low-band noise DF work, the "Coastal Navigator" RDF receiver as shown here. https://powerlinenoiseallentexas.wordpress.com/df-equipment/ I ha
Concur with Christopher. Based on signature and having tracked down these kinds of things too. Side note: I have seen 'lobing' on power line noise BUT the 'lobes' (the interference 'pulses') are grou
A few questions to help fill in some details:: Do you live in the city or the country? How close are your neighbors? Are your utilities underground? Does it have AC line nose characteristics? Is the
Good point Ken/LBI. Ken W7EKB, what time did this start last night? And, did it cut off this morning? Jim WB5WPA Sounds like a defective starter in a street lamp. KenWA2LBI Sent from my S5 -- O
