Yes, Ed, it can be done!!!! The installation at DIA in Denver is pretty clean. Dave - WØLEV -- *Dave - WØLEV* *Just Let Darwin Work* _______________________________________________ RFI mailing list R
Ed, why has FCC not taken action with the whole solar power industry? Dave - WØLEV -- *Dave - WØLEV* *Just Let Darwin Work* _______________________________________________ RFI mailing list RFI@contes
There are presently a couple of small MF/SW SDR receivers on the market with waterfall. The Malachite (spelling) come to mind. There are a few others as well. Here are a few links (no connection to p
We had a saying at Sperry: "There is never enough time to do it right the first time, but always enough time (and budget) for rework". I believe this applies to Solar Edge and the whole solar power i
There are good technical reasons for measuring radiated emissions above 30 MHz and conducted emissions below 30 MHz. The majority of products when tested with required cabling attached and operating
If you don't require "DC to Light" coverage with an SDR, even the USB dongles can offer you full coverage of any amateur band below 70-cm. Cost is quite minimal and HDSDR operates them and offers bot
An effective common mode choke on the mains conductors should pass all three conductors through the core. For a 2.4-inch OD core, three turns are usually good. Too many more will increase the capacit
FairRite has an excellent presentation on determining ferrite toroid material. All that's required is some method of measuring both the physical dimensions of the toroid (a ruler or calipers) and the
This information should also be included in the ARRL Handbook - Ed ? Dave - WØLEV -- *Dave - WØLEV* *Just Let Darwin Work* _______________________________________________ RFI mailing list RFI@contest
Nothing fancy. I'll attach an image of the test fixture I use. It is not appropriate for frequencies much above 54 MHz, but works fine for HF on downward. In determining ferrite material, one does no
QUOTE: "I stunned that these manufactures do not have to comply with an FCC regulations. " Yep, so are most of us. When in creation will FCC take a stand on these RFI polluters. It's almost across th
And the "official" reply from FCC to the impacted (RFI) coverage areas for AM BC, "Increase your output power." Sure.....Yea......That costs the BCer money both for a new transmitter and continuing a
If the FCC had nipped this problem in the beginning, we would not be where we are today. That was the time when FCC still had budget and manpower to perform their functions. They still did very littl
We, the citizens of the country, did not choose the downsizing of the FCC. We had absolutely no say in the decision. And.......selling off a natural resource to fund a bunch of lawyers while gutting
QUOTE W2TTT, GORDON: " As for VZW and AT&T staffing, there are surprisingly few engineers available and equipped to troubleshoot noise and other forms of interference, but they do an excellent job wh
Steve, I believe the real push here is to do something about the whole Solar Power industry when we have whole cities and states, California, especially, mandating all new construction be outfitted w
You got it, Gary. And the lawyers have no idea what RF is and isn't. Dave - WØLEV -- *Dave - WØLEV* *Just Let Darwin Work* _______________________________________________ RFI mailing list RFI@contest
Several years ago as an EMC engineer, I had an assembly of home automation equipment I had to test for regulatory purposes - FCC. It contained many audio amplifiers which were Class-D and Class-E for
The largest EMC/RFI hole with the FCC these days is their lack of enforcing the regs. already on the books. Part 15 is pretty much ignored and nothing much stops SMPS from China. And not to mention t
While I was still working I can't relate how many problems I solved by simply installing a common mode choke as you just did. But since home appliances are exempt from any FCC regulation wrt EMC/RFI,
