Great video Rob as always. I had the same issue with cheap LED's. I had installed them in my house in the kitchen. When they were on, it completely obliterated 6m and caused S9+20 noise across the band. Swapped them out for Philips LED's and that fixed the problem!
The early LED bulbs were terrible. They had so many components and switching transients and not to mention enough capacitors to repair an antique radio! Really....our club actually tried this in a tube radio a few years ago.
Shocking thing is, it's NOT just the rubbish people buy cheap on the internet.. Branded products (at least in the EU) from makers of legacy lighting products are sold that completely wipe out 10m - 70cm with a wall of white noise You may not notice until it's toggled. The hidden scourge :/
Same here. The old bulbs I started with were expensive if I recall...that's why I used them in the garage instead of throwing them out when we replaced the bulbs in our kitchen
when I start listening, I try to turn off everything that is not necessary, but now sources of disturbance are everywhere, in your case probably given the proximity and the good transformer power supply, the disturbances were emitted by the cheap lamp at the level of non-electrical radio interference, it would be interesting to try to power the radio with a battery and see what happens.Ciao
I have horrible buzzing here, makes radio near impossible to use. It's not coming from anything in the house so it must be a neighbor or power lines, it never stops.
@@SevenFortyOne I gather it's the controlled charging process for Li-ion that makes them noisy. The worst of them (from you know where) also create power line RFI.
I've been involved with electronics manufacturing and design professionally, and in particular power supplies and battery charging circuits used in fire alarm panels found in buildings. Chargers can be pretty RF quiet when designed properly. The quality of parts used, circuit design, and board layout all factor in as does the amount of testing and certification that is done to certify the design meets standards. Like you said, those battery chargers are made as quickly and cheaply as possible by companies that don't really care about meeting RFI requirements. I have a charger I got at Walmart that is so bad you can hear it whine with your ears when its is charging a battery.
It’s amazing how noisy LED bulbs are. Some of the cheaper USB adapters are noisy too. 73 de K2CJB
I put a set of LED headlights in my Jeep XJ and it caused interference in my car radio and ham radio on both AM and FM.
Good Video Rob!
bummer...I'll keep that in mind if I ever think about upgrading my bulbs
Yep it's them cheap led light bulbs everytime. They have no FCC part acceptance because they are imported.

Hi Rob,
Glad you were able to determine where the RFI originated and a solution. Stay safe. 73 WJ3U
A friend put LED bulbs in his new garage. He couldn't even hear a local FM broadcast station where he had line of site to the Tx tower.
Yikes! That's bad

That's a bummer...sorry you are facing this
Most Chinese LED Lights Stinks!
Had exactly the same problem on 2 meters and tracked it down to an LED desk lamp!
Interesting. Nice job, and as always thanks for the videos!
thanks for the tip, Sylvania lights it is then.
The noise floor in my neighborhood rises significantly around Xmas. Lots of Xmas LED decorations around! 73
Those led strings are bad for sure!
@@SevenFortyOneguess I won't be decorating my antennas with LED strings. 73
I can’t resist…
How many light bulbs does it take to screw up a Ham?
😀😀😀
It depends on how many the CB'er had for sale.
Have a rather large box of incandescent light bulb. No LEDs for me. If it ain't broke let's break it. LOL
Nice work.
How many hams does it take to screw in a light bulb? 😂
You think LEDs are bad? Try ride-on mower battery chargers! They can wipe out a suburb.
Ill keep that in mind!

But it’s green energy 😂
Lightbulbs, wifi and solar charge controllers can all screw with ya.
Yeah, just put antenna outside
