I just uploaded a video onto YouTube that documents wideband RFI on 20 meters that I tracked down to my neighbors invisible fence transmitter, and it's not the typical approximate 7 or 10 KHz interva
I haven't used our Invisible Fence system for several years, but it did generate RFI. I easily stopped it with a Corcom AC line filter. 73, Jim N7US I just uploaded a video onto YouTube that document
Hi Don - Interesting! Years ago, when I got my first Invisible-Fence brand system in my old house, I wondered if it would be a problem, but was told that the underground loop operated at around 17 KH
Don, Our invisible fence is the typical 10khz variety, but I found a 3 layer approach worked well... each did a bit of reduction, and together it was enough. Maybe that multi layer approach can help
Hi Joe and gang, Thanks for the comments. I'm not looking for a home brew solution as I already know what a solution is based on my past experiences with invisible fence systems including my own. As
Had a problem with the next door neighbor's inground dog fence. Wiped me out on 160M with a receive antenna within 10' of the buried wire. Provided a Corcom 10VK6 filter to the installer of the dog
Hi Tony, Yes, I remember your case. I'm the one that told you about the 10VK6 back in 2016 per a recommendation I had received from the Innotek engineering department. 73, Don (wd8dsb) ______________
There is no record on the FCC OET site for KE3-3002587 which is shown on the image of the label as the FCC ID number for the wireless transmitter - Part 15, Class B, Subpart B, intentional radiators.
And thanks again Don for the help. I felt more comfortable with an off the shelf solution and have it installed by the original installer.Easy fix with great results.N2TK, Tony --Original Message--
Hi Tony, Glad to hear the 10VK6 did the trick for you and I thought that was the case. I actually have a 10VK6 sitting here specifically for this application that I can provide the Invisible Fence in
I found the certification record easily. https://apps.fcc.gov/oetcf/tcb/reports/Tcb731GrantForm.cfm?mode=COPY&RequestTimeout=500&tcb_code=&application_id=rQqvlnXl0jI%2BsFf%2Fvos1Hw%3D%3D&fcc_id=KE3-3
Ed, please let me know why I did not find it under the listing on the OET for the FCC ID number. That is usually where I find such things. Please educate me on how you found it. Dave - WØLEV -- *Dave
I didn't have to do anything special, Dave. I just typed in KE3 in the grantee box and scrolled down the resultant list until I saw the full ID number. It was about 75% down the list if 116 items tha
My wife sez I'm always in a hurry. Well, she is correct. A search on the specific number did not yield anything. And I did not visually search. As you found, it's there. Next time I'll slow down a bi
Here is an interesting update regarding the 20 meters broadband RFI being generated by my neighbors Invisible Fence transmitter that's not the typical RFI encountered with such systems. We tried a br

Opps, I just spotted an error in my text. I should have said capacitive reactance and Xc, not inductive reactance and XL (sorry for the error in my text). My calculations were correct, but I went bra
