Hi Mac, The APC AV C Type 2 Outlet Wall Mount Power Filter has two built in receptacles (female jacks) on one end and on the opposite end is a jack for a typical line cord and it actually comes with
Hi Mac, I had to find the data sheet for the ACP unit to figure out that it came with a 2 foot power-cord and sure enough Mike (W9RE) received a power cord with the unit. The descriptions by various
Late last year I stumbled upon a sick AM radio broadcast station in Indianapolis (WNTS, 1590 KHz) while driving to a hams QTH to track down some powerline noise. The station was generating splatter a
Hi Rob, The station (WNTS) actually did a great job responding to our interference complaint as they jumped on the problem almost immediately, they brought in an RF Engineer from far away, and they r
Hi Gary, Funny that you bring this up (annual inspection). It just so happens that WNTS had just gone through their annual inspection (measurements) 2 weeks prior to the splatter showing up and I saw
Hi Gary, All of the annual measurements appeared to be at the fully licensed daytime power level of 5 KW but the station was running much more power than this to the surprise of the engineer when we
Hi Alan, Great write up, and very timely. This past weekend a fellow ham asked what he could do to eliminate RFI that was being generated by his furnace, and I forwarded your write up to him to help
Utter disappointment Saturday morning when I was getting ready for the Stew Perry 160 meter contest when I noticed new RFI on 160 meters as well as 80 meters to my East, and spent the morning trackin
Hi Stephanie, I'm using a very cheap RTL-SDR dongle that has a TCXO from Nooelec and it provides coverage from 25 to 1750 MHz (cost me about $25), and I typically use HDSDR software with it. For HF I
Hi Chuck, I'm using a Canon PowerShot SX30 IS that was gifted to me from a friend that wanted a newer model. For the night time movie and still shot I used my Iphone 13 pro. The Canon is amazing, and
Hi Ed, Feel free to use my video as you desire. This case was the loudest I have encountered when listening up on 438 MHz. I normally just need 136 MHz with lots of attenuation but since this pole wa
Update: I called this bad pole into Duke Energy yesterday morning (pole number, distance and direction from a known address and intersection, details of the bad cable, etc.), and this morning I recei
Hi Eddie, Yep, same thing here. I work with numerous utility companies in the Central Indiana area and they are all different regarding what department/group within their company deals with RFI repor
Final Update: Duke Energy line crew showed up around 10:30am today which was just a little over 24 hours from when I reported the problem. I was only able to stop by and say hello to the crew because
Hello Alan, Tim, Jim, and gang, Just thought I would provide a little update, and also a very interesting observation regarding the problem at Mikes (W9RE) in which his stubs or band pass filters for
Hi Alan, Thanks, and I looked through this document. The document is very good like others we have come across regarding best practices to avoid PIM, but like other documents it does not provide the
Here is a link to one of the best documents I have come across regarding PIM and the Cellular Industry and it really is applicable to PIM in general. https://www.anritsu.com/en-US/test-measurement/te
I work hard keeping my noise floor on 160 meters low and hopefully equal between my 3 different pennant RX antennas that point 40, 160, and 300 degrees from my QTH. This winter I've struggled with an
Hi Dave, You can see details on this loop at the 3:08 mark of this youtube video: https://youtu.be/vDB8rAwVt5Y The video also shows how I use it. 73, Don (wd8dsb) ____________________________________
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
